CCWDM Mux Demux

CCWDM Mux Demux (Continuous Wavelength Division Multiplexing Multiplexer Demultiplexer) is a continuous wavelength division multiplexer and demultiplexer for wavelength multiplexing and demultiplexing in optical communication networks. Compared with traditional CWDM (Coarse Wavelength Division Multiplexing, with larger wavelength separation) and DWDM (Dense Wavelength Division Multiplexing, with smaller wavelength separation), CCWDM has a more compact wavelength spacing and provides a higher wavelength density.
