Differences the Between Termination Box for Fiber Optic Cable and Fiber Distribution Box(2022年)

Grandway — 2022-03-18T17:59:28+0900

https://www.grandwaytelecom.com/En/Index/pageView/catid/22/id/29.html

We all know that the optical fiber cable distribution box is a box where the two ends of the optical fiber network are ready to be directly connected to the optoelectronic equipment with jumpers. The size of the terminal box can be determined according to the site conditions or the number of optical fiber cores used. So, do you know what the principle of the optical cable terminal box is? What are the differences between optical cable terminal box and optical fiber distribution box?

Ⅰ. The principle of the termination box for fiber optic cable

The optical cable terminal box is divided into: engineering plastic ABS material and high-quality cold-rolled steel plate. The inlet port has a plastic protective ring, which reduces the friction between the optical cable and the housing and plays a protective role. The outlet port is made of plastic material, which will not scratch the pigtail. The small outlets are arranged in an orderly manner, which is easy to install and beautiful.

Ⅱ. Differences the between termination box for fiber optic cable and fiber distribution box

1. Different in nature

The optical cable terminal box is an auxiliary equipment for terminal wiring in the optical fiber transmission communication network. It is suitable for the direct and branch connection of indoor optical cables and protects the optical fiber joints. The optical fiber distribution box is suitable for the wiring connection of optical cables and optical communication equipment. Through the adapter in the wiring box, the optical signal is led out with the optical jumper to realize the optical wiring function.

2. The scope of application is different

As the carrier of information transmission, optical termination box for fiber optic cable has become an important pillar of modern communication with optical fiber hardware as the medium of information transmission. The ftth distribution box is used for the introduction, fixing and open circuit protection of optical cables, fusion and protection of optical fibers, storage of pigtails, storage and management of jumpers, fixed connection and cross-connection of optical fibers. At the same time, value-added module units such as optical splitters and wavelength division multiplexers can be installed according to customer requirements.

3. Different features

The optical cable terminal box has the functions of optical cable introduction, wiring pigtails leading out and fixing and protecting the optical cables, wiring pigtails and the performance of the optical fibers in it from damage. The optical fiber distribution box is suitable for the protective connection of optical cables and distribution pigtails, and is also suitable for the collection of optical fiber terminal points in the optical fiber access network.

The Introduction to Optical Time Domain Reflectometer(2022年)

Grandway — 2022-03-18T17:55:21+0900

https://www.grandwaytelecom.com/En/Index/pageView/catid/22/id/28.html

Optical time domain reflectometer working, OTDR for short, is one of the most indispensable devices in communication engineering construction and maintenance and is widely used in communication engineering.

Optical time domain reflectometer is also used in the production of optical fibers and cables,construction and acceptance, as well as the maintenance of optical cable line. It is also used by users in continuous loss monitoring, obstacles finding and line maintenance.

Technicians can view the contour of the whole system, identify and measure the span, connection points and joints of optical fibers. The trace of optical time domain reflectometer gives the position and size of the attenuation value of the system, such as the position and loss of any connector, connection point, abnormal fiber or fiber break point.

The Working Principle of Optical Time Domain Reflectometer

The testing principle of fttx otdr is that the laser source emits a certain intensity and wavelength of light beam to the tested fiber. Due to the traits of the fiber itself and the inhomogeneity of impurities, light propagates in the fiber and produces Rayleigh scattering.

Due to mechanical connection and fracture, fresnel reflection occurs when light is transmitted in optical fiber. Some of the scattered and reflected light are transmitted back to the input. The test is to be carried out by the optical time domain reflectometer.

Development and current trends of FTTH technology(2022年)

Grandway — 2022-03-18T17:50:28+0900

https://www.grandwaytelecom.com/En/Index/pageView/catid/22/id/21.html

Fiber to the home (FTTH) is a modern optical network access technology. At present, triple play services and high-speed Internet access are now widely accepted by most people around the world.
Even so, people's desire to increase Internet speed is still widespread, which has prompted fierce competition between telecommunications companies (and their copper cable networks) and cable companies (and their coaxial networks). The competition revealed the fact that access to the Internet through copper wires has reached its limit, and the only hope for increasing bandwidth in the future is to install optical fibers.

Current trends of FTTH
The situation of FTTH solution on a global scale is very inconsistent. The deployment of optical fiber to homes and the use of standards in any country depends on the history of broadband Internet access in a particular country/region, regional inconsistencies, issues of local telecommunications companies and technology. As telecom operators will increase the adoption of home fiber optics, the compound annual growth rate of the global home fiber optic market will be positive. Among all regions, North America and Japan will become the world's highest market share for household optical fiber. The regions with the lowest FTTH penetration rate are the Middle East and Africa (MEA) and Latin America. Online books, intelligent systems, online entertainment, advanced cloud computing, e-government, e-learning and e-health are the driving forces that will drive the growth of FTTH in the next decade.

Development of FTTH Technology
The fiber to the home ftth technology is not a new concept. France, Canada, and Japan began to study the fiber-to-the-home implementation in 1978, and the United States also join the research in 1995. But it died in the end because of the high cost and lack of market demand. With the continuous advancement of technology, the needs of various countries for the development of the information society and the drive of various telecommunications policies, the application of FTTH technology has entered an era of great strides since 2004. Among them, Japan is the most enthusiastic country in the world for FTTH. The development of FTTH has been in a leading position. As of 2007, there have been more than 10 million FTTH users in Japan. It is expected to reach 20 million households by 2010. In the United States, Verizon is the most active service provider in promoting FTTH services and has begun to provide HD Digital TV services. As of 2005, it has covered 3 million users. The development of FTTH in Europe was slow. Until the end of 2002, two FTTH operators in Europe-Sweden's B2 company and Italy's E. biscom has a total of 160,000 FTTH users.

What can FTTH bring us?
Fiber to the home (FTTH) is a transmission method of optical fiber communication, which directly connects the optical fiber to the user's home or where the user needs it. This optical fiber communication method realizes the "last mile" information transmission. Its advantages: firstly, information dissemination is fast, secondly, it is convenient to contact, and thirdly, it improves efficiency, which will greatly improve people's quality of life and work efficiency.

6 motors splicer is the true core-alignment splicer(2022年)

Grandway — 2022-03-18T17:46:08+0900

https://www.grandwaytelecom.com/En/Index/pageView/catid/22/id/15.html

Generally speaking, cladding alignment splicer equip with four motors, ZL, ZR, X and Y motors. However for core-alignment splicer, there are two more motors, ZL, ZR, X, Y, FocusX and FocusY. FocusX and FocusY motors make the splicer the true core-alignment splicer.

The following figure shows the principle why 6 motors splicer can observe fiber core.

LED illumination comes from left side. We can regard it as parallel beam. Because of the refractive index difference between cladding and core, a part of the beam condenses. Setting focal plane to the adequate position, we can catch the condensed beam. We can see it as a white line in the fiber image on the splicer.

Upper figure shows about standard SM fiber. Lower figure shows about smaller core size fiber. You can see the difference of adequate focal planes. Thus, the adequate focal plane depends on the core size. Focus motor leads the focal plane to the adequate one according to fiber type.

Recently, many types of fibers are in the market. For example, BIF, bend insensitive fibers, G.654, core size is different from conventional standard SM fiber. To splice such fibers with low loss, to set focal plane precisely is very important.

To be a true “core alignment splicer”, the splicer must equip 6 motors is necessary, ZL, ZR, X, Y and FocusX, FocusY.

What is ODN in telecom?(2022年)

Grandway — 2022-03-18T17:35:11+0900

https://www.grandwaytelecom.com/about-us/blog/23.html

ODN is an integral part of the PON system. It provides an optical transmission medium for the physical connection between ONU and OLT. The reach range is 20 kilometers or more. In ODN telecom, fiber optic cables, fiber optic connectors, passive optical splitters and auxiliary components cooperate with each other. In addition, ODN is an indispensable path for PON data transmission, and its quality directly affects the performance, reliability and scalability of the PON system.

Design of ODN
ODN telecom specifically has five parts, namely feeder fiber,optical distribution point, distribution fiber, optical access point, and incoming fiber. The feeder fiber starts from the optical distribution frame (ODF) in the central office (CO) telecommunications room and ends at the optical distribution point for long-distance coverage. The distribution fiber from the optical distribution point to the optical access point distributes the optical fiber to the area next to it. The introduction of optical fiber connects the optical access point to the terminal (ONT), so that the optical fiber can enter the user's home.

Deployment strategy of ODN optical distribution network
Deployment analysis is crucial in determining the placement or positioning strategy of OLT and ONU deployment in ODN optical distribution network design, because it will affect the future enhancement of the network and the realization of the complete concept of FTTH. In order to support high-rise buildings with multi-units, OLT equipment that specializes in providing services to the building can be placed. The ONU deployment is divided according to the implementation strategies of FTTH, FTTC, FTTB, FTTO, and FTTCab.
