check the optical module parameters

In the use of optical modules, it is inevitable to encounter a variety of problems. To reduce the fault phenomenon and ensure the stability of the optical module. There are different detection functions for optical modules.   The 1X9 module mainly detects the signal in the communication proc... Read More

optical module output optical power

The Output Power refers to the average output optical power of the light source at the sending end of the optical module, also known as 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. (Where W or mW is a linear ... Read More

Optical fiber interface of optical module

It refers to the interface that connects an optical module to an optical fiber jumper. It can be connected through a single-mode or multi-mode optical fiber. The following is an analysis based on different interfaces. At present, there are mainly optical interfaces on the market: MPO, LC, SC, FC,... Read More

Optical Fiber Transmission Loss

The reason why optical fiber replaces the long-distance transmission of the network cable is that optical fiber transmission has low loss, and its loss is mainly divided into the following: Loss is the loss of light energy caused by the absorption and scattering of the medium (air) and leakage (t...
