Coarse Wavelength Division Multiplexing (CWDM) is the use of the Fiber Optical Multiplexer to different wavelengths of light signals multiplexed to a single optical fiber for transmission, at the receiving end of the link, with the Fiber Optical Multiplexer fiber mixed signal is decomposed into different wavelengths signal, connected to the respective receiving apparatus.100GHz CWDM Mux/Demux Module over a single or duplex single mode fiber is quite common to extend your overall bandwidth. It offer high stability and reliability, and has small package size. Its operating wavelength is from 1270nm to 1610nm(1261nm-1611nm) which totally offer 18 channels with 20nm channel spacing.
