CWDM Mux Demux

CWDM Mux Demux (Coarse Wavelength Division Multiplexing Multiplexer Demultiplexer) is a type of wavelength division multiplexer and demultiplexer used for wavelength multiplexing and demultiplexing in optical communication networks.

Specifically, CWDM Mux Demux is used to combine multiple optical signals, each corresponding to a different wavelength, into a single optical fiber for transmission, or to demultiplex multiple wavelengths of optical signals from a single optical fiber into separate optical signals.
