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.
