How to View SFP Module Optical Signal Strength?


To determine whether the SFP optical module (transmitter and receiver) operates at the appropriate signal level, you can view the SFP optical module information, which is critical, including fiber type, transmit optical power planning, and optical reception power.

Other switches, such as Cisco and Brocade SAN switches, are available in the CLI (Command Line Interface), which is used to view detailed information about SFP optical modules, including rate, serial number, part number, and receive / send direction optical signals strength. The following picture flashes detailed information about SFP optical modules in Cisco and Brocade switches, including optical signal strength.

Brocade CLI-Display Interface Optical Module Details:

As can be seen from the above results, although Cisco and Brocade measure the optical signal strength of different methods, but they are supplied SFP optical module at the time of signal strength and useful optical signal strength planning. As long as the signal strength of the SFP optical module is within the useful plan, the SFP optical module can operate normally.

We can see that the method that Cisco and Brocade marking the signal strength is different. But both of them offer the current signal strength and the range of effective optical signal strength of the SFP modules. As long as the SFP signal strength lies in the valid range, the SFP module can be considered to work normally.

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
