When the interface of the installed optical module fails to work properly, you can troubleshoot the problem according to the following three methods: 1)Check the Alarm information of the optical module. Through the alarm information, if there is a problem with reception, it is generally caused by...

The value of the optical power will have the most intuitive and obvious influence on the signal during the transmission process, and this optical power is also the easiest to test. This value can be tested through the optical power. Optical power – use an optical power meter to test whether...

In using the use of optical modules, it is unavoidable to encounter a variety of problems. In order to reduce the problematic failure phenomenon, but also to protect the stability of the optical module through. There will exist different detection functions for optical modules. 1X9 module is main...

The output optical power (Output Power) refers to the average output optical power of the light source at the transmitting end of the optical module, also called the output optical power, which can be understood as the intensity of light. Formula: P(dBm)=10Log(P/1mW) The unit is W or mW or dBm. (...

This refers to the interface of an optical module to a fibre optic patch cable, which can be connected via single mode or multimode fibre optic cable. The following is an analysis of this according to the different interfaces.  At present, the main optical interfaces on the market are: MPO, LC, S...

At present, there are FBG, FB and DFB lasers, Among them, the most commonly used lasers are FP and DFB.   FBG: Fiber Bragg Grating. FP: Fabry-Perot, Fabry-Perot Laser Diode DFB: Distributed Feedback Laser, Distributed Feedback Laser Diode   For the mainstream commonly used FB and DFB. The DFB las...
