People who are familiar with compatible optical transceiver know that some manufacturers will encrypt their network equipment (such as switches) which means the modules must match the equipment that they produce otherwise the modules cannot work. The quality of the module can directly affect the transmission of the optical fiber link. Although the quality of the original transceiver is very good, the price is very high. The compatible optical transceiver produced by Gearlink is completely comparable to the original one, but the price of compatible optical transceiver is much lower, such as qsfp28 qsfp+ compatibility transceiver, qsfp56 qsfp28 compatibility transceiver, sfp+ sfp compatibility transceiver and so on. As an optical transceiver manufacturer, we have strict compatibility testing standards and procedures. All the modules will undergo compatibility testing before shipment which can ensure they are 100% compatible with Cisco. Juniper. Huawei. HP and H3C etc.

What Is SFP Compatibility ？
When switch products leave the factory, some brand switch manufacturers will make some personalized restrictions on the switch to identify the type of optical module used on the switch or prevent the use of third-party modules, like putting a lock on the device. Only the matching key can be opened and used normally. If the module transceiver does not meet the switch requirements, the optical transceiver may fail to work or generate device alarms. We all know that the original switch brand optical module is very expensive, but whether it is a brand or a third-party manufacturer, it is necessary to ask a special optical module manufacturer (foundry) to make the compatible optical transceiver according to the protocol and standard of the optical module. That is to say, the quality of the modules produced by the foundry is the same as that of the products sold to other brands. Because of the brand effect, the compatible optical transceiver price has doubled after leaving the factory. In this case, compatible optical modules emerge as the times require, and third-party modules can independently decode and write codes through the analysis of the modules, which can ensure that the optical modules can be used normally on brand switches. This is a compatible optical module. Compatible optical modules make it much easier and more convenient for customers to purchase and install, and greatly reduce the cost of procurement. This is also the reason why compatible optical transceiver have become the mainstream optical modules in the market.

Compatible Optical Transceiver Benefits
Cisco, HP, Juniper and other big companies advertise that only their own SFP modules can work with their devices, but at high prices. What's more, some vendors fail to declare whether the SFP slots on their devices are compatible with other vendors' standard SFP. This can cause problems for users when their devices can't communicate with SFP devices purchased from other vendors. Compatible SFP as long as it meets the MSA standard, is also a standard product. With the official hardware function consistent, compatible with different telecom manufacturers equipment. Therefore, using transceivers with sfp compatibility means you can save a lot of money and don't have to worry about your equipment and SFP coming from different vendors.

How to Use a Compatible SFP Module?
Here are some guidelines for using compatible optical transceiver correctly.

Step 1, check your transceiver module and device ports.

Some transceiver modules are easy to mix because of their similar appearance. For example, SFP and SFP+. If the SFP+ modules are plugged into an SFP port, they will still work, but the transfer speed will be limited to 1 Gbps. Otherwise, the SFP module will not be connected when it is inserted into the SFP+ port.

Step 2: Ensure that the SFP module has the same wavelength at both ends. Therefore, you'd better check the SPECIFICATIONS of the SFP module carefully.

Step 3: Select the right optical fiber type, which is the main factor to ensure SFP compatibility. Therefore, you must verify that the optical fibers at both ends of the SFP module should be of the same type.

Step 4, ensure that both ports are compatible with the SFP module.

How to Ensure Quality of Compatible Optical Transceiver?
1. Professional testing process

When you purchase a compatible optical transceiver, make sure you test it on the switch. Generally, a tested compatible optical module can guarantee perfect performance on your network.

2. Warranty policy

If the warranty lasts longer, the quality of the compatible optical transceiver may be more reliable and stable.

3. Professional Suppliers

With a rigorous quality control system and years of experience, Gearlink guarantees a reliable and stable connection to your high-speed fiber optic transmission system. All the raw materials we use are safe and their performance is comparable to the original.

Transceiver Compatibility Matrix FAQs
Q
What Does An SFP Do?
A
WH Gearlink’SFP transceiver is hot pluggable optical module. SFP means small form-factor pluggable. It can be simply understood as an upgraded version of GBIC. Some switch manufacturers call SFP module a miniature GBIC (MINI-GBIC ). The China SFP optical module is mainly composed of lasers, and the maximum data rate can reach 1.25G.

Q
Why Is There Such A Big Gap Between The Original Price And The Third-Party Compatibility Price?
A
There are not many large equipment manufacturers, and there are only so many user choices. In the case of occupying most of the market, the market transceiver price can only be customized by large manufacturers, which leads to the expensive price of optical modules. There are more third-party compatibility modules manufacturers, so the price will be much lower.

Q
What Are The Advantages Of The Compatibility Module Compared To The Original Module?
A
Compatible optical modules are generally applicable to equipment of any brand and have a wider range of transceiver applications. Original optical modules can only be used on equipment of their own brand. Once the branded modules are out of stock, the equipment will not work properly, affecting the project process.
