DWDM Mux Demux

DWDM Mux Demux (Dense Wavelength Division Multiplexing Multiplexer Demultiplexer) is a dense wavelength division multiplexer and demultiplexer used for wavelength multiplexing and demultiplexing in optical communication networks.

Specifically, DWDM 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.
