GLSUN coarse wavelength division multiplexing (CWDM) is a wavelength division multiplexing (WDM) technology that combines multiple signals at various wavelengths for simultaneous transmission over fiber cables.
CWDM can realize the multiplexing and demultiplexing between two communication channel. This CWDM Multiplexers can expand the capacity of single fiber to achieve bidirectional communication, which can widely used in optical network upgrade and expansion, or introduce new comprehensive business etc.
·Low insertion loss
·Low PDL
·High channel isolation
·Excellent environmental reliability
·WDM system
·CATV
