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...
