The Difference Between Fiber Patch Cord and Fiber Pigtail
Fiber pigtails patch cords are cables directly connected to desktop computers or devices to facilitate device connection and management. Patch cords have a thicker protective layer and are often used between terminal boxes and optical transceivers.
Only one end of the pigtail has a connector. The other end is an optical fiber connector connected to other optical fiber cores in the form of fusion splicing and generally appears in the optical fiber terminal box.

Ⅰ. Specifications and types of fiber patch cords and pigtails
Optical fiber patch cord is generally distinguished by single-mode and multi-mode in data transmission equipment. The color of the single-mode patch cord is usually yellow. There are two wavelengths, 1310nm, and 1550nm. The transmission distance is 10km and 40km, respectively; The color of the multi-mode patch cord is usually orange, aqua, magenta, etc. The wavelength is 850nm, and the transmission distance is 500m. According to the joint type, it can also be divided into the following types:
FC type patch cord: round fiber optic connector, additional metal sleeve reinforcement, and the fixing method is a turnbuckle.
SC patch cord: Rectangular connector, the fixed way is plug-in latch type, no need to rotate.
ST-type patch cord: circular connector, using the snap-on connection and the fixing method is a turnbuckle.
LC-type patch cord: square connector, the fixing method is made by the principle of easy-to-operate modular jack (RJ) latch.
The pigtails mainly include single-core pigtails, dual-core pigtails, 4-core pigtails, 12-core bundle pigtails, 12-color bundle pigtails, SC, FC bundle pigtails, LC bundles Pigtails, and ST bundle pigtails. In addition to these, it can be divided into the following types:
Bundle pigtail: This pigtail is also called a pigtail bundle, which is more popular than other types of pigtails and has a wide range of applications.
Ribbon pigtail: The ribbon pigtail is the same as the bundle pigtail. Both are multi-core pigtails. The ribbon pigtail contains 12-core fibers. One end is used for fusion splicing, and the other is equipped with a connector.
Armored pigtail: The outermost layer of this pigtail has an extra metal protective sheath than the conventional pigtail so that it will be more durable than ordinary pigtails.
Optical fiber pigtail: low insertion loss, high return loss, good interchangeability, and repetitive plugging and insertion, very convenient to use.
Waterproof pigtail: It is suitable for harsh environments with a dense protective cover and waterproof sealing connector.

Ⅱ. Application of fiber optic patch cord and pigtail
Optical fiber optic patch cords are mainly used to connect optical fiber distribution frame or optical fiber information socket and switch, the connection between controller and switch, the connection between the switch and desktop computer, and the connection between optical fiber information socket and desktop computer. It can be applied to management, equipment room, and work area subsystems.
Pigtails are mainly used in optical fiber communication systems, optical fiber access networks, optical data transmission, optical fiber CATV, local area networks (LAN), test equipment, optical fiber sensors, serial servers, FTTH/FTTX, telecommunication networks, and pre-terminated installations.

The Difference Between 100G QSFP28 Fiber Optical Transceiver and 100G CFP4 Fiber Optical Transceiver(2023年01月29日)

tscom — 2023-01-29T17:10:20+0900

https://www.china-tscom.com/the-difference-between-100g-qsfp28-fiber-optical-transceiver-and-100g-cfp4-fiber-optical-transceiver.html

1. What is fiber optical transceiver
The100g optical transceiver is an optoelectronic device that performs electro-optical and photoelectric conversion. The fiber optical transceiver is a carrier, acting as the transmitting end to convert electrical signals into optical signals, and as the receiving end to convert the optical signals into electrical signals.
Fiber optical transceivers can be divided into SFP, SFP+, XFP, QSFP+, QSFP28, QSFPDD according to the packaging form, and the types of optical interfaces include SC and LC.
Fiber optical transceivers can be divided into 155M, 622M, 1.25G (1024M), 10G (10*1024M), 40G, 25G, 100g optical modules, 200G, 400G, etc. according to the transmission rate.
The higher the transmission rate of the fiber optical transceiver is, the shorter the transmission distance. According to the transmission distance, it can be divided into short distance (2KM and below), medium distance (10 to 20KM), long distance (above 30 to 40KM), including 550M, 300M, 2KM, 10KM, 20KM, 40KM, 60KM, 80KM, 100KM, 120KM.
The longer the wavelength of the fiber optical transceiver, the longer the transmission distance. According to the wavelength of transceiver, it can be divided into 850nm(MM), 1310(nm), 1550(nm), CWDM, DWDM
Fiber optical transceivers are divided into single-mode fiber optical transceivers and multi-mode fiber optical transceivers. Single-mode fiber optical transceivers are suitable for long-distance transmission; multi-mode transceivers are suitable for short-distance transmission. Therefore, the price of a single-mode fiber optical transceiver is a bit more expensive than that of a multi-mode fiber optical transceiver.

2. The difference between 100G QSFP28 fiber optical transceiver and 100G CFP4 fiber optical transceiver
The 100G QSFP28 fiber optical transceiver is suitable for a variety of transmission distances and application scenarios, which is mainly used in 100G Ethernet and EDRInfiniBand, and is an important part of the 100G network. It has the advantages of low power consumption, small size, high port density, etc., and is liked by the majority of customers.
The 100G CFP fiber optical transceiver has gone through CFP, CFP2, and now CFP4 fiber optical transceiver. The technology is mature and can support hot swap. However, its volume is larger than that of QSFP28 fiber optical transceiver, with few categories, and it is not suitable for many application scenarios.
CFP4 is specified by CFP MSA, and its size is slightly larger than that of QSFP28. The interface between MAC and PHY varies according to the application, and control and monitoring are achieved through the MDIO interface. Generally it is used for access networks and metropolitan area networks.
100G QSFP28 is specified by IEEE. It is smaller in size than CFP4. It is currently one of the 100G modules with the highest level of integration (CXP is more integrated). The interface between MAC and PHY is CAUI-4, and control and monitoring are achieved through the I2C interface. Generally it is used in data centers.

Structures and Applications of Fiber Bragg Grating Sensors(2023年01月29日)

tscom — 2023-01-29T17:09:01+0900

https://www.china-tscom.com/structures-and-applications-of-fiber-bragg-grating-sensors.html

Ⅰ. Learn about fiber Bragg grating sensors
Fiber Bragg grating sensor can be used as a kind of fiber sensor. Like the optical fiber sensor, it has many irreplaceable advantages compared with the traditional electric sensor, such as: no electromagnetic interference, lightweight, small size, no corrosion, etc. Fiber Bragg grating sensors are commonly used in structural deformation and temperature monitoring. Short-period fiber grating sensors are commonly used, and their reflection wavelengths are called Bragg wavelengths. Such sensors are called FBG sensors.
Fiber Bragg grating sensor is a kind of fiber sensor with the highest frequency and the widest range, which includes FBG strain sensor, FBG temperature sensor, fiber Bragg grating pressure sensor, etc. This sensor can change the wavelength of the reflected light wave according to the environmental temperature and changes. Fiber bragg grating sensors use holographic interferometry or phase masking to expose a small section of light-sensitive optical fiber to light waves with a periodic distribution of light intensity. In this way, the optical refractive index of the optical fiber will be permanently changed according to the intensity of the irradiated light wave. The periodic changes in the refractive index of light caused by this method are called fiber Bragg gratings.
Ⅱ. The structure of fiber Bragg grating sensors
The structure of the fiber Bragg grating sensor is to use an ultraviolet laser to write a section of grating on the fiber core. When the continuous broadband light Li emitted by the light source enters through the transmission fiber, a narrowband light Lr is selectively reflected back at the grating, and the remaining broadband light Lt continues to pass through, and is reflected at the next grating with different center wavelengths. The grating array forms a fiber Bragg grating (FBG) sensor network. The center wavelength of the reflected light of each FBG is λ, λ=2nΛ, where n is the effective refractive index of the core; Λ is the modulation period of the core refractive index.

Ⅲ. Application of fiber Bragg grating sensors
1. The accelerometer can be used for many engineering measurements, such as vibration, incident angle, event recording, platform stability, vehicle suspension control, earthquake monitoring, and pacemaker control. The accelerometer made with fiber Bragg grating sensor shows good performance. And the key is to choose a reliable fiber bragg grating manufacturer.
2. The hydrophone made of fiber grating is used to measure the underwater sound field, which can achieve good linear response, high sensitivity, high stability, wide dynamic range (90dB) and wide operating frequency range (from a few kHz to a few MHz) ).
3. The structural deformation monitoring sensor of the mechanical tool system made of fiber grating. Such a fiber Bragg grating sensor can detect the deformation of the practical structure in the order of microns with an error of 0.4%.

Solutions for 40G QSFP+DAC/AOC Direct Connection Cable(2023年01月29日)

tscom — 2023-01-29T17:07:43+0900

https://www.china-tscom.com/solutions-for-40g-qsfpdacaoc-direct-connection-cable.html

Direct cable is an ideal short-distance connection solution to replace optical transceivers. It can be divided into two categories: high-speed cable (DAC AOC) and active optical cable (AOC). With cheap price, easy use and other advantages, it has been widely concerned by people. Now, with the wide use of 40G network, QSFP+ direct connection cable is also gradually popular. Now T&S will introduce the common QSFP+ direct cable solutions in the market in detail through this article.

40G QSFP+ AOC adopts optical cable as the transmission medium, which has the characteristics of lightweight and long transmission distance. In addition, there is also no need to worry about electromagnetic interference (EMI) when using an active cable.

1. 40G QSFP+ to QSFP+ AOC
Like 40G QSFP+ to QSFP+ DAC, this active optical cable (AOC) is preterminated with two QSFP+ fiber transceivers at both ends. The transmission distance of our 40G AOC can reach more than 100m, but the price is higher than that of high-speed cable.

2. 40G QSFP+ to 4XSFP + AOC
The active optical cable is preterminated with a QSFP+ fiber optical transceiver at one end and preterminated with 4 10G SFP+ optical transceivers at the other end. It can also be used for 10G and 40G network connections, but they can travel much longer than high-speed cables.
QSFP+DAC high-speed cables and AOCs are essential components of 40G networks. These optical devices can help you save a lot of network deployment costs.

Reason Analysis of Using AOC Active Optical Cable in Data Center Wiring(2023年01月29日)

tscom — 2023-01-29T17:06:56+0900

https://www.china-tscom.com/reason-analysis-of-using-aoc-active-optical-cable-in-data-center-wiring.html

40G/100G AOC active optical cable has been globally introduced throughout the aoc data center field. Compared to 40G DAC copper cable, 40G AOC active optical cable has unparalleled advantages in data transmission environment above 7 meters, including the smaller size, lighter weight, easier bending, easier management, longer signal transmission distance, etc. In the data center, the same goals can be achieved with a 40G SR4 optical transceiver. The differences between 40G AOC active optical cable and SR4 optical transceiver are analyzed as follows:

1. Insertion loss analysis of 40G AOC active optical cable and SR4 optical transceiver

With the same transmission distance, for SR4 optical transceiver, different optical fiber jumpers that are connected to the same module will produce different insertion loss and return loss, which is basically a common problem. However, as long as the variation is within the range, there will be no significant change in the eye map and other related indexes.

The AOC active optical cable which is well made is basically stable and has better rocking performance. The repeated test of the SR4 optical transceiver produced a large fluctuation.

2. Four-quadrant test of 40G AOC active optical cable and SR4 optical transceiver

It is measured at four combinations of input voltage and signal amplitude to ensure that the performance can be maintained at both the lowest and highest voltages and temperatures. AOC active optical cable is required to pass quadrant tests with a wide temperature range to ensure that the MPO interface and cable of AOC will not melt at high temperatures. The performance change of MPO interface itself at high and low temperatures can meet the change of 0.3 dB, and the materials used are PEI materials that can resist the temperature of above 120 degrees.

As an all-in-one product, the all-in-one test ensures the performance of the product, which may be more stable than SR4 optical transceiver that adopts MPO jumper with uncertain performance. Compared with SR4 optical transceiver that confirms the quality through optical eye diagram, AOC active optical cable mainly uses the eye diagram to judge the quality of indicators.

3. DDM monitoring of 40G AOC active optical cable and SR4 optical transceiver

QSFP+ SR4 optical transceiver has the DDM monitoring function. When receiving coupling, the ADC value of the receiver can be monitored in real time to determine the optimal coupling. Therefore, SR4 is more superior than AOC in terms of receiving sensitivity.

4. Transmission distance of 40G AOC active optical cable and SR4 optical transceiver

There is not much difference in the OM3 fibers, but the 40G QSFP+ SR4 optical transceiver provides better performance control. QSFP+SR4 is recommended if you want to achieve a longer distance (> 300 m) transmission.

Active fiber optical cable (AOC) is recommended based on the data connection in the data center, because it provides better wiring consistency and repeatability, and the closed ends are easier to avoid the effects of environmental and vibration oscillations. If there is a failure, it can be replaced directly without the need to carry out a series of end-to-plug tests of 40G QSFP+SR4 optical transceiver and MPO jumper on site, which is more beneficial to save costs.

What Are the Components of Internet of Things?(2022年10月26日)

tscom — 2022-10-26T12:45:21+0900

https://www.china-tscom.com/what-are-the-components-of-internet-of-things.html

What are the basic internet of things components? To answer this question, this article introduces the relative analysis and knowledge in detail, hoping to help you to solve the question in a simpler and easier way.

Ⅰ. What are the basic components of IoT?

IoT can be roughly classified into the following four levels: sensing layer, network layer, platform layer and application layer. The details are as follows.

1. Sensing and Identification Layer

The sensing layer is the foundation of the overall framework of IoT, and is an important link between the physical the information world. In this layer, we can sense the object and its surroundings through sensors. In this way, the object is given the ability to speak and release information, such as sound sensors, pressure sensors, photoelectric sensors and so on. The sensing layer is responsible for collecting information for IoT.

2. Network Construction Layer

As a linking component, this layer is responsible for transmitting the sensory information to the upper layer( the IOT cloud platform) and the command to the lower layer(the application layer). The network layer transmits the massive amount of information mainly through IOT, Internet and mobile communication network.

3. Platform Management Layer

As the core of the overall framework of the IoT, this layer is in charge of data storage, retrieving, application, security and privacy protection. It is responsible for integrating and utilizing the information collected at the sensing layer through big data, cloud computing and other technologies, to provide scientific and effective guidance for mankind while applying the technology in specific fields.

4. Comprehensive Application Layer

The IoT is ultimately to be applied to the various walks of life. After the IoT cloud platform process the information transmitted by the objects, the valuable information will be applied to people's life and work, such as smart logistics, smart health, food safety and smart park.

Ⅱ. Characteristics of the component of IoT

The basic characteristics of the IoT can be summarized as overall perception, reliable transmission and intelligent processing. Looking from the perspective of communication objects and processes, the information interaction between things and people, things and things is the core of the IoT.

Overall perception: perceive and obtain a variety of object information by using radio frequency identification, QR code, smart sensors and other sensing devices.

Reliable transmission: transmit object information timely and accurately through the integration of the Internet and wireless networks to facilitate information exchange.

What Are the Common Fiber Optic Attenuators?(2022年10月26日)

tscom — 2022-10-26T12:44:48+0900

https://www.china-tscom.com/what-are-the-common-fiber-optic-attenuators.html

Fiber optic attenuator is an optical device that can reduce the energy of optical signal. Through the attenuation of input optical power, it can avoid the distortion of optical receiver due to too strong input optical power.

As an optical passive device, fiber attenuator is usually made of attenuation fiber with metal ions. It can adjust the optical power to the required level. It is mainly used in optical communication system to debug the optical power performance, calibrate the calibration of optical fiber instrument and reduce the attenuation of optical fiber signal.

1. Why use fiber optic attenuators?

The intensity of optical signal received by various optical receiving equipment is limited, and the equipment can not work normally if the optical power is too weak or too strong within a certain range. When the optical power is too strong, the optical power will be adjusted by light attenuation to reduce it to an appropriate range, otherwise even if the equipment can be used, it will affect the service life.

The attenuation power of fixed fiber optic attenuator is fixed (such as 1dB, 5dB, 10dB). The attenuation power of a 3dB fiber optic attenuator is 3dB. This fiber optic attenuator is generally used in telecommunication networks, optical fiber test equipment, local area network (LAN) and cable television (CATV) systems. Fixed fiber attenuators can be divided into on-line and plug-in types.

The shape of plug-in optical fiber attenuator is similar to that of optical connector. The difference is that both ends of plug-in fiber optic attenuator are male connector interface and female connector interface respectively. This fiber optic attenuator either uses air gap to achieve attenuation, or uses metal ions to attenuate optical fiber to achieve attenuation effect.

The attenuation power of adjustable fixed optical attenuator is not invariable, but changes with the change of conditions. Its variation span is 0.5dB, 20dB, 50dB, etc. And some even reach the accuracy of 0.1dB and 0.01dB. Tunable fiber attenuators are generally used for accurate testing and measurement of optical fibers. At the same time, they are also widely used in erbium-doped fiber amplifiers. Their function is to balance the optical signal power in different channels.

2. Fiber optic attenuators are divided into the following four categories according to different interfaces

SC fiber optic attenuator: it is applied to SC optical fiber interface, which is similar to RJ-45 interface, but the SC interface is more flat and the contact inside is a copper column.

LC fiber optic attenuator: it is applied to LC optical fiber interface and can be used to connect SFP module. Modular jack (RJ) latch mechanism is adopted, which is easy to operate and commonly used in routers.

FC fiber optic attenuator: it is applied to FC optical fiber interface. The outer sleeve is wrapped with metal sleeve, and the fastening method is turnbuckle. It is generally used on the ODF side and is mostly used for distribution frames.

ST fiber optic attenuator: it is applied to st optical fiber interface. The shell is circular and fastened with turnbuckle. It is commonly used in optical fiber distribution frame.

https://www.china-tscom.com/what-are-the-application-scenarios-of-optical-transceivers.html

The rapid development of science and technology makes people's lives change with each passing day. With the continuous advancement of applications such as 5G, big data, blockchain, cloud computing, Internet of Things, and artificial intelligence, data flow has increased unprecedentedly, and data center interconnection has become a research hotspot in optical communications.

The current high-speed optical transceiver application scenarios are mainly Internet data center networks, metropolitan area network optical transmission networks, and telecommunication networks represented by 5G bearer networks.

Ⅰ. The application of fiber optical transceivers in data centers

The current data center is no longer just one or a few computer rooms, but a group of data center clusters. In order to realize the normal operation of various Internet services and application markets, coordinated operation between data centers is required. The real-time mass exchange of information between data centers has created the demand for data center interconnection networks, and optical fiber communication has become a necessary means to achieve interconnection.

Different from traditional transmission equipment that connected to telecommunication networks, the interconnection of data centers requires equipment of higher speed, lower power consumption, and smaller size in order to achieve larger and denser transmission of information. The optical transceiver is a core factor that determines whether these performances can be achieved. The information network mainly uses optical fiber as the transmission medium, but the calculation and analysis must be based on electrical signals at present, and the optical transceiver is the core to realize the photoelectric conversion.

Ⅱ. Data center communication optical transceivers can be divided into three categories according to different connection types

(1) From data centers to users, it is generated by end-user behaviors such as accessing the cloud to browse webpages, send and receive emails, and video streams;

(2) Data center interconnection is mainly used for data replication, software and system upgrades;

(3) It is mainly used for information storage, generation and mining inside the data center.

According to forecasts, data center internal communications account for more than 70% of data center communications. The great development of data center construction has given birth to the development of high-speed optical transceivers.

1. Data flow continues to grow, and the trend of large-scale and flat data centers promotes the development of optical transceivers in two aspects:

(1) The increasing demand for transmission rate; (2) The increasing demand for quantity.

The large-scale trend of data centers has led to an increase in transmission distance. The transmission distance of multimode optical fiber is limited by the increase in signal rate, and it is expected to be gradually replaced by single-mode optical fiber. The cost of an optical fiber link consists of two parts: an optical transceiver and an optical fiber, and there are different applicable solutions for different distances.

2. In terms of medium and long-distance interconnection required for data center communication, there are two revolutionary solutions born from MSA:

(1) PSM4 (Parallel Single Mode 4 lanes);

(2) CWDM4 (Coarse Wavelength Division Multiplexer 4 lanes).

Among them, PSM4 fiber usage is 4 times that of CWDM4. When the link distance is longer, the cost of the CWDM4 solution is relatively low.

3. The application of optical transceivers in China's data centers.

The interconnection of internal switches in US data centers is dominated by single-mode optical fiber. In the 100G era, CWDM4/PSM4 optical transceivers are widely used, and in the 400G era, DR4 is currently the dominant; the interconnection between servers and switches mostly uses cable DAC. With the passage of time and the increase of module rate, the proportion of multi-mode fiber and direct-connect cable DAC in the internal interconnection scheme of US data centers will become lower and lower.

The interconnection of internal switches in China's data centers is dominated by multi-mode fiber, and the proportion of single-mode fiber is gradually increasing. At present, there is little demand for 400G in China. In the 100G era, SR4/CWDM4 modules are used, and most of the interconnections between servers and switches use AOC active optical cables.

What Are the Advantages of Direct Attach Cable Over Active Optical Cable?(2022年10月26日)

tscom — 2022-10-26T12:43:45+0900

https://www.china-tscom.com/what-are-the-advantages-of-direct-attach-cable-over-active-optic-cable.html

In recent years, with the rapid development of data centers and increasing data transmission among manufacturers and users, the rates of optical transceivers have evolved from 25G and 40G to the current 100G, 200G, etc. Correspondingly, AOC has been developed to a new level.

Active optical cable (AOC) can be said to be a new type of transmission medium for high-density and high-bandwidth applications in the era of big data. Compared with traditional cables, active optical cables have high transmission rates, long transmission distances, low energy consumption and convenient way to use. Active optical cables benefit communication equipment with the huge advantages of optical transmission, and it is an ideal transmission cable for data centers, consumer electronics and other fields.

However, why can direct attach cables still develop in the market when AOC has such huge advantages?

1. First, let's take a look at direct attach cable

Direct attach cable (DAC) is usually a fixed-length cable assembly with fixed connectors at both ends.

The connector used at the end of direct attach cable is the same as the interface of the optical transceivers, but compared to the optical transceiver, the connector module on the direct attach cable does not have expensive optical lasers and other electronic components, thus greatly saving the cost and power consumption in short-distance applications. As a low-cost and high-efficient high-speed data communication solution that replaces optical transceivers, it can be widely used in storage area networks, data centers, and high-performance computer connections by connecting switches to routers or servers.

2. Advantages of direct attach cable (DAC) over active optical cable

(1) In terms of transmission distance, direct attach cables have shorter transmission distances than active optical cables, so they are suitable for short-distance cabling in data centers.

(2) In terms of material, the direct attach cable is made of copper core inside. The copper cable is a natural radiator with good heat dissipation effect, which is energy saving and environmentally friendly.

(3) In terms of power consumption, direct attach cables have low power consumption.

3. The current rates and types of direct attach cable DAC

(1) 100G QSFP28 DAC direct attach cable

The 100G QSFP28 cable assembly is a high-performance and cost-effective I/O solution. Direct attach cable assemblies can meet and exceed the requirements for 100 Gigabit Ethernet, InfiniBand EDR as well as temperature requirements for performance and reliability. The cable complies with SFF-8436 specifications and provide connections between devices using QSFP ports.

(2) 100GE QSFP28 to 25G SFP28 DAC direct attach cable

QSFP28 4x25SFP28 cable is high-performance and cost-effective, which can realize the interconnection between SFP28 and QSFP28. The hybrid cable complies with SFF-8402 and SFF-8665 specifications. It can be applied to realize low-power and short-reach interconnection.

Each transmits data at a rate of 25Gb/s, providing an aggregate rate of 100gb/s.

(3) 25GE SFP28 DAC direct attach passive copper cable

SFP28 passive cable assembly is a high-performance and cost-effective I/O solution for connecting 25G Ethernet.

(4) 56G QSFP+ DAC copper cable

QSFP+ copper cable is compatible with SFF-8436. It can be applied to realize low-power and short-reach interconnection. Each transmits data up to 14Gb/s, providing an aggregation rate of 40gb/s.

What Are the 40G QSFQ+ Fiber Optical Transceivers and Their Differences?(2022年10月26日)

tscom — 2022-10-26T12:43:14+0900

https://www.china-tscom.com/what-are-the-40g-qsfp-fiber-optical-transceivers-and-their-differences.html

40G networks are widely used in data centers.40g qsfp transceivers are the mainstream devices for interconnection between data center equipment. So what are the main types of 40g optical transceiver? What are the differences between them?

The three types of 40G QSFP are 40G QSFP+ SR4, 40G QSFP+ LR4 and 40G QSFP+ PSM LR4. They are all compliant with 40G Ethernet, and data center switches support Infiniband 4xSDR, DDR and QSR. It has four data transmission channels, each with a transmission rate of about 10Gbps, and the simultaneous transmission of four channels can achieve a transmission rate of 40Gbps. It also supports hot-swappable QSFP package with an ultra-low power consumption.

1. 40G QSFP+ SR4 transceiver

In 40G network transmission, it is usually used with MPO/MTP connectors. It uses multi-mode optical fiber for transmission. When matched with OM3 multi-mode optical fiber jumper, it can support a transmission distance of 100 meters, and when it is matched with multi-mode optical fiber OM4 jumper, it can support a transmission distance of 150 meters;

2. 40G QSFP+ LR4 fiber optical transceiver

40G QSFP+ LR4 fiber optical transceivers are generally connected with LC connectors, which support hot-swappable electrical interfaces with a lower energy consumption, and support the transmission distance of single-mode optical fiber up to 10km;

3. Comparison of 40G QSFP+ SR4 and 40G QSFP+PSM LR4 fiber optical transceivers

The 40G QSFP+ PSM LR4 fiber optical transceiver utilizes parallel-designed MPO/MTP interfaces with four full-duplex channels, and can achieve a transmission distance of 2km through 8 independent optical cables with single-mode fibers, and supports power consumption <3.5W.

40G QSFP+ SR4 fiber optical transceiver and 40G QSFP+ PSM LR4 transceiver have the same connector type, but 40G QSFP+ SR4 fiber optical transceiver is commonly used for multi-mode fiber transmission, and the transmission distance is short. 40G QSFP+ PSM LR4 fiber optical transceiver is mostly used for single-mode fiber transmission, and the transmission distance is long.

4. 40G LR4 PSM fiber optical transceiver

The working principle of the 40g qsfp+ aoc cable transceiver is the same as that of the 40G QSFP+ SR4 fiber optical transceiver, which converts the photoelectric signal through the laser array; the 40G LR4 PSM transceiver is suitable for long-distance transmission, and the 40G QSFP+ SR4 fiber optical transceiver is suitable for short-distance transmission.

Compared with the 40G QSFP+ SR4 fiber optical transceiver, although both are suitable for long-distance transmission, the 40G LR4 PSM fiber optical transceiver requires 8 single-mode optical fibers for transmission, and the 40G QSFP+ SR4 fiber optical transceiver only uses 2 single-mode optical fibers for transmission.

There are many fiber optic transceiver manufacturers, but we are one of the best choices for you.

Is 200G Active Optical Cable Good? What Are the Advantages?(2022年08月17日)

tscom — 2022-08-11T15:30:23+0900

https://www.china-tscom.com/is-200g-active-optic-cable-good-what-are-the-advantages.html

Is 200G MPO Cable Good? What Are the Advantages?

In recent years, optical networks have developed rapidly. In order to ensure the stability and flexibility of transmission, users and manufacturers require a newer type of transmission product to achieve higher-performance signal transmission. To meet this need, active optical cable (AOC) appeared.

Active optical cable refers to a communication cable that needs to use external energy to convert electrical signals into optical signals or convert optical signals into electrical signals in the communication process. The optical transceivers at both ends of the optic cable provide photoelectric conversion and optical transmission functions. AOC uses one optical cable to connect two high-density connectors.

At present, the active optical cable products on the market include 10G SFP + AOC, 25G SFP28 AOC, 28G SFP28 AOC, 40G QSFP + AOC, 56G QSFP + AOC, 100G QSFP28 AOC, 120G CXP AOC, 200G-SR4 QSFP DD AOC.

Now, what we are introducing is 200G-SR4 QSFP DD AOC.

1. What is 200G AOC?
The concept of active optical cable has been described in detail above. In a nutshell, qsfp 200g AOC is an active optical cable with a transmission rate of 200G.

2. Overview of 200G AOC
It is a pluggable and parallel optical fiber QSFP with eight channel and dual density, which is used for 2x100g Ethernet applications. This optical transceiver is high performance for short-distance multi-channel data communication and interconnection applications.
It integrates 8 data channels in each direction with a bandwidth of 8x25.78125Gbps. Each channel can use OM3 fiber to transmit 70m or OM4 fiber to transmit 100m. These transceivers are designed to use a multimode fiber optical system with a nominal wavelength of 850nm.

The electrical interface uses 76 contact edge type connectors. The optical interface uses a 24-fiber MTP (MPO) connector. The module integrates technology-proven circuits and VCSEL technology to provide reliable services which is long-life, high-performance and consistent.

3. Advantages of 200G AOC
Facing the trend of the data center which is featured by high speed, low cost, and high density, 200G AOC provides a better solution.

Compared with active optical cables of other speeds, 200G active optical cables have greater advantages in link and data. In terms of transmission distance, AOC can achieve a longer transmission distance than copper cable. Moreover, it also has better aerodynamic heat dissipation in the cabling system.

Summary: 200G AOC has a higher transmission data rate and a higher density layout and it can achieve the same transmission rate with a relatively low cabling cost under the same conditions.

Why Use Active Fiber Optical Cable?(2022年08月16日)

tscom — 2022-08-11T15:29:56+0900

https://www.china-tscom.com/why-use-active-fiber-optic-cable.html

passive optical cables
active optical components

Active optical components, also known as AOC, AOC is the abbreviation of Active Optical Fiber. At one end of the active optical cable, the data is input into an electrical signal, and the electrical signal is converted into an optical signal of a specific wavelength through a photoelectric conversion device. The optical signal is modulated and coupled and then input into the transmission optical cable. After the optical signal reaches the other end, the photoelectric detection device detects, amplifies, and processes the signals, and then the corresponding electrical signal is output. The reverse transmission principle is the same. Passive optical cables have obvious price advantages over active optical cables, so why use active optical cables?

1. Features of active optical cable

With the advent of the era of big data, fiber optics communications are developing at a high speed, and passive optical cables or copper-based cable systems have been unable to keep up with the pace, appearing stretched, and slowly failing to meet the needs of users and data transmission. As the demand for new products as the main transmission medium for high-performance computing and data centers continues to grow, active optical cable (AOC) products have emerged.

Active optical cables are used mainly because their components can replace copper technology in data centers and high-performance computing (HPC) applications. As far as we know, passive optical cables are heavy and bulky, and do not meet the high-density requirements of data centers. Moreover, due to the nature of electrical signals, electromagnetic interference (EMI) limits the performance and reliability of copper. However, active optical cables break through the limitations of passive optical cables and play an important role in high-speed data transmission.

Passive optical cables provide direct transmission between corresponding optical cables. active optical cables have the same effect, but some limitations of passive optical cables can be overcome by embedding optical or electronic components in the connector.

2. Advantages of active optical cable:

(1) Greater bandwidth: no equipment upgrade is required.

(2) Lightweight: much lighter than high-speed cables.

(3) Low electromagnetic interference: Since optical fiber is a kind of dielectric, it is not easy to be affected by electromagnetic interference.

(4) High transmission rate, long transmission distance, low energy consumption, convenient use, etc.

Why is the Threshold of Optical Transceiver/AOC/DAC Technology Low?(2022年08月15日)

tscom — 2022-08-11T15:29:33+0900

https://www.china-tscom.com/why-is-the-threshold-of-optical-transceiveraocdac-technology-low.html

Why is the Threshold of Optical Transceiver/AOC DAC Technology Low?

1. The statement that low technical threshold of optical transceiver/AOC and active optical cable/DAC is not rigorous

Some high-end products can be only produced by a few manufacturers in the world, such as 400G optical transceivers. In addition, for the same product, such as 100G single-mode optical transceivers, when most optical transceiver manufacturers can only achieve 10 kilometers, a few manufacturers can already achieve 40 kilometers. But for the vast majority of mature products, the threshold in this field is indeed too low, which leads to a large number of small workshops, and dozens of people can start an optical transceiver company.

2. Reasons for the low threshold of optic communication transceiver/AOC/DAC technology

The reason for the low threshold is that the optical transceiver/AOC active optic cable/DAC can basically be regarded as a pure hardware product. Although the driver is also running on the MCU controller, they are relatively simple and standard things (Of course, there are still differences between manufacturers, and many compatibility problems come from this difference).

The core components used in this hardware product are available to everyone, and everyone can easily get the hardware solutions of major manufacturers for reference and imitation, and even some optical transceiver suppliers will directly provide coupled boards to downstream manufacturers. .

This means that for optical transceiver manufacturers, in terms of many mature products, the technical solutions used by everyone are highly similar, and there are not too many thresholds.

Why Do 400G Optical Transceiver Prefer QSFP-DD?(2022年08月14日)

tscom — 2022-08-11T15:29:06+0900

https://www.china-tscom.com/why-do-400g-optical-transceiver-prefer-qsfpdd.html

Why Do 400G Optical Transceiver Prefer QSFP-DD?

Optical transceiver has developed to 400G optical transceiver, and manufacturers are stepping up research and development to seize the hot spot. Many mainstream manufacturers choose 400g qsfp dd as the package of 400 optical transceivers, but why do 400G optical transceivers prefer QSFP-DD? Does it mean that QSFP-DD will be the main package of 400g transceivers in the future?

A good packaging must first support the types of transmission media and optical transceivers that are widely used in the networking industry. The transmission media include passive direct connection copper cable (DAC), multimode fiber (MMF) and single-mode fiber (SMF). Optical transceivers, active copper cables, and active optical cables include the 100Gb /s, 200Gb/s, and 400Gb/s series defined by Ethernet, Fibre Channel, and InfiniBand standards. Furthermore, the port density of the new package should be the same as that of the already deployed network. Finally, the backward compatibility of the new package with the already widely used QSFP package is critical for industry adoption. The QSFP-DD optical transceiver is a package that meets all the above conditions.

I. The development history of QSFP-DD optical transceiver

On March 21, 2016, the plan to develop QSFP-DD high-speed interface was started.

On September 19, 2016, version 1.0 of the QSFP-DD hardware specification containing the drawings was released.

On March 13, 2017, version 2.0 of the QSFP-DD hardware specification and QSFP-DD white paper were released.

On September 19, 2017, version 3.0 of the QSFP-DD hardware specification was released, along with the CS Connector specification.

On March 13, 2018, the QSFP-DD Thermal Design White Paper was released, addressing the issue of how to evaluate the thermal performance of the QSFP-DD module in a high-performance data center environment.

On August 30, 2018, it was announced that the QSFP-DD package had successfully passed the equipment interoperability test, and the QSFP-DD package optical transceiver was now ready for official use.

On 18 September 2018, version 4.0 of the QSFP-DD hardware specification and version 3.0 of the General Management Interface Specification for 8/16 Channel Placable Optical Modular were released.

So far, QSFP-DD MSA is relatively completed, and QSFP-DD optical transceivers of leading optical transceiver manufacturers were also listed in that period.

II. The application in the research and development of 400G optical transceiver

The QSFP-DD dual-density four-channel small pluggable package is a high-speed pluggable module package defined by the QSFP-DD MSA team as the preferred package for 400G optical transceivers, enabling data centers to effectively grow and expand cloud capacity as needed.

III. Characteristics of 400G QSFP-DD optical transceiver

The compatibility of the 400G qsfp+ patch cord transceiver with the QSFP solution is one of its main advantages. The original QSFP28 module can still be used; you just need to insert another module.

In conclusion, the characteristics of the QSFP-DD optical transceiver package have unparalleled advantages in 400G applications (such as data center interconnection). It is expected that the world's leading ultra-large data center will soon deploy 400G, and QSFP-DD may become the mainstream package.

What is the Difference Between AOC and Optical Transceiver?(2022年08月13日)

tscom — 2022-08-11T15:28:42+0900

https://www.china-tscom.com/what-is-the-difference-between-aoc-and-optical-transceiver.html

What is the Difference Between AOC and Optical Module Transceiver?

AOC active optical cable is an optical fiber with a module attached to each end, which is equivalent to a cable and a module.

AOC active optical cable is also widely used by many customers, because its cost is cheaper than that of two separate modules plus one optical fiber.

1. From a technical point of view, what is the difference between AOC and optical transceiver + optical module fiber?

Like optical transceiver, AOC active optical cable is still optically driven with the same core components inside. Their difference is mainly referring to the process difficulty.

For optical transceiver, when the internal components are coupled, the situation of the opposite end may be very different, so it needs to adopt different situations, which requires high level lasers with high manual operation complexity.

As for AOC active optical cable, the opposite end is fixed, so there is no need to consider various situations. It sets low requirements for the laser with relatively simple peripheral components and simple manual operation. This can reduce some costs and is why the price of AOC active optical cable is lower than that of two modules + one optical fiber.

However, since none of the most costly core components is saved, the difference in cost is not very significant (note: cost is not equal to selling price).

Of course, even for the same aoc company, their optical transceivers and AOC active optical cables may have different chip solutions and coupling methods. This is why the optical transceivers and AOC active optical cables of the same manufacturer may perform differently on the same third-party equipment, but in general, they are all driven by light, so the difference will not be too great.

2. The cost of AOC active optical cable and optical transceiver is different

Although the cost of AOC active optical cable is lower, compared with transceivers, the AOC active optical cable also has disadvantages.

For example, in the AOC cables, if a module or optical fiber has a problem, all parts need to be replaced, but the optical transceiver does not require the same; especially in some environments where the wiring is completed, the AOC active optical cable needs to be pulled out, which is a very troublesome task.

In addition, if the equipment at both ends are from different manufacturers, for the optical transceiver solution, transceivers from different manufacturers can be purchased separately to avoid compatibility issues. If the AOC active optical cable solution is used, you can only ask the AOC active optical cable supplier to write the code in advance, and it may even need to be marked on the AOC cables, like which end corresponds to which manufacturer.

What Is the Difference between 100G Active Optical Cable and 100G Direct Attach Cable?(2022年08月12日)

tscom — 2022-08-11T15:28:18+0900

https://www.china-tscom.com/what-is-the-difference-between-100g-active-optic-cable-and-100g-direct-attach-cable.html

What Is the Difference between 100G Active Optical Cable and 100G Direct Attach Cable?

We know that both 100G active optical cables (AOC) and 100g fibre cable are used to transmit data. However, there are some differences between 100G active optical cables and 100G direct attach cables. Next, we will introduce the difference between these two types of cables in detail.

1. What is 100G active optical cable?

100G active optical cable refers to the communication cable that needs to use external energy to convert electrical signals into optical signals or convert optical signals into electrical signals during the communication process. The optical transceivers at both ends of the optical cable provide photoelectric conversion and optical transmission functions, and the transmission rate reaches 100Gb/s.

2. What is 100G direct attach cable?

100G direct attach cable adopts silver-plated conductor and foamed insulated core wire, which has excellent low attenuation performance and low delay performance, so that the signal transmission is accurate and precise, and the transmission speed can be improved. It is a short-distance connection solution that replaces the optical transceiver. Moreover, the price of this cable is much cheaper than that of the same type of optical transceivers, and it is widely welcomed in short-distance connection applications.

3. Structure of 100G AOC active optical cable

Simply put, the active optical cable is composed of two optical transceivers and an optical cable jumper. The optical fiber transceiver at both ends consists of OM3 or OM4 multimode fibers of different lengths.

4. Structure of 100G direct attach cable

Direct attach cable is abbreviated as DAC. Its both ends are connected to switches or servers to realize short-distance transmission. High-speed cables can be divided into passive direct attach cables and active direct attach cables. Active direct attach cables has only one more driving chip than passive high speed cables. The "optical transceivers" on direct attach cables are not optical transceivers in the true sense. They have no components and can only transmit electrical signals. Therefore, direct attach cables are cheaper than other ordinary optical devices. Even if the same port is used as interfaces of optical transceivers, direct attach cables can also effectively save costs and reduce power consumption in short-distance applications. This is the reason why people choose direct attach cables.

5. Classification of 100G AOC active optic cable

100G AOC active optical cable has two types: 100G QSFP28 active optical cable and 100G QSFP28 to 4X 25G SFP28 active optical cable. The former has an optical transceiver receiver at both ends to realize one-to-one transmission, and the latter has a 100G QSFP28 interface at one end, and four 25GSFP28 ports at the other end, which can provide customers with 100G data transmission.

6. Classification of 100G direct attach cables

There are two types of 100G direct attach cables: 100G QSFP28 DAC and 100G QSFP28 to 25G SFP28 DAC. The former has an optical transceiver receiver at both ends to realizes one-to-one transmission, and the latter has a 100G QSFP28 at one end of interface and four 25GSFP28 interfaces at the other end, which can provide customers with 100G data transmission.

It should be noted here that although the classification of the two is much the same, the optical transceiver of the active optical cable has a built-in laser, while there is no laser inside the direct attach cable.
