How exactly to Use a Compatible SFP Module?

 You might find a compatible SFP transceiver cannot work effectively in the branded switch. This is not due to the defective compatible SFP transceiver, but by improper behavior. Listed below are several guides that you can properly use a compatible SFP module.

Check your transceiver module and device port

Some transceiver modules are simple to be mixed due to the similar appearances. For instance, SFP and SFP+. SFP provides 1Gbps of data and SFP+ supports the info rates up to 10 Gbps. Getting the same size, an Cisco GLC-SX-MM module can fit seamlessly in to the SFP+ port on the switch and vice versa. If you insert an SFP+ module into an SFP port, they'll still work however the transmission speed will be limited at 1 Gbps. On the other hand, there will be no connection when an SFP module is inserted into an SFP+ port.

Make sure that the SFP modules have exactly the same wavelength at either end

It is recognized to us that the SFP module is used for data transmission. The transmission process is definitely that the electrical signals in one side are converted into optical signals, then the lights are transmitted through the fiber and can be changed into electrical signals on the other end of the SFP module. To make sure this technique, the SFP modules at either end must have the same wavelength. So, you’d better consider the specifications of the SFP modules carefully.

Pick the correct fiber type

Choosing the right fiber type can be a significant factor to ensure the SFP compatibility aswell. So, you need to verify the fibers on both ends of the SFP modules, that ought to become the same type. The standardized colors on the outer jacket of fibers can help you identify them. What’s even more, remember using the corresponding fiber cables.

Ensure both ports are compatible with the SFP module

It is necessary that the ports on your own devices can accept the SFP modules you wish to use. As stated above, some brands aren't appropriate for the SFP modules from other suppliers. Even though using the compatible SFP modules, you’d better check the standards of ports firstly.

Differences between cisco GLC-T and cisco GLC-TE

 Cisco GLC-T, GLC-TE and SFP-GE-T optical modules are all Gigabit port optical modules with RJ45 interface and 100m transmission distance. They are cost-saving solutions for Gigabit Ethernet connection in data center, access network and storage area network applications. Therefore, these three types of optical modules are often difficult to distinguish. In fact, the transmission effect of these three optical modules is the same, which optical module can achieve Gigabit transmission, but it is certainly noteworthy that the original Cisco GLC-T and SPF-GE-T optical modules were terminated on June 1, 2017 and replaced by GLC-TE optical module. SFP-GE-T optical module with NEBS 3 ESD function needs to be selected if it is traded directly with the telecommunications company (which requires NEBS).The price of GLC-T and GLC-TE optical modules is low, and they can also meet the needs of Gigabit Ethernet. The Cisco Gigabit optical modules provided by Easy Communications can meet a large number

Why the sfp transceiver not work

 The failure of the sfp optical module is divided into the failure of the transmitter and the failure of the receiver. Through the analysis of the main causes of the phenomenon, the most likely problems are mainly concentrated in the following aspects: The optical port of the  1000base SFP transceiver  is contaminated and damaged Because of the pollution and damage of the optical interface of the module, the loss of the optical link is increased, so that the optical fiber link is unreachable. The main reasons for this phenomenon are the following four points: 1. The optical port of the SFP optical module has been exposed to the environment for a long time, resulting in contamination and contamination of the SFP optical port; 2. The end face of the fiber jumper connected to the  Cisco SFP-10g-sr  optical module has been contaminated, and the SFP optical port provides been contaminated; 3. Improper operation of the end face of the optical connector with pigtails, scratching of the finish
