How to solve when the optical module fails?
Nov 11 , 2022
During the use of the optical transceiver module, various problems will inevitably occur. The following summarizes the main reasons and solutions in the event of failure. Matters needing attention before use 1. Do not connect optical modules with different wavelengths. Due to the different transmission loss and dispersion in the fiber, the transmission distance corresponding to different wavelengt...

What are the performance indicators that affect the WDM wavelength division multiplexer?
Nov 15 , 2022
The technology of simultaneously transmitting information of two or more optical wavelength signals through different optical channels in the same fiber is called wavelength division multiplexing (WDM). WDM (Wavelength Division Multiplexing) is to combine two or more optical carrier signals of different wavelengths (carrying various information) at the transmitting end through a multiplexer, and c...

Explanation of relevant knowledge points of WDM network
Dec 27 , 2022
A WDM network is a network that deploys optical WDM fiber links, where each link carries multiple wavelength channels. WDM, an acronym for Wavelength Division Multiplexing, is a technology that multiplexes multiple signals on a single optical fiber by using optical carriers of different wavelengths using lasers or LEDs. There is a multiplexer and a demultiplexer at each end of the WDM. A multiplex...
