DWDM Device, Dense Wavelength Division Multiplexers

Product Details

Dense Wavelength Division Multiplexing (DWDM) is a fiber-optic transmission technology. DWDM can realize the multiplexing and demultiplexing between two communication channel, and available on ITU channel spacing of 100/200 GHz. This DWDM device 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
