Optical CWDM Mux Demux Module: 16CH CWDM MUX / DEMUX Optical Module, 2.0mm LC/ PC ABS BOX with Express port
CWDM Optical Module is also called coarse WDM, the mux / demux combines up to 18 different wavelengths of signals from different fibers into one fiber, or separates up to 18 different wavelengths from a single fiber into 18 separate fibers.CWDM technology uses ITU standard 20nm spacing between the wavelengths, from 1270nm to 1610nm.
