WDM MUX DEMUX
WDM is multiplexing/demultiplexing card based on WDM technology is mainly used in CWDM or DWDM systems to complete the multiplexing and demultiplexing functions. At the transmitting end, multiplexes optical signals of different ITU-T DWDM wavelengths into a single optical fiber for transmission; at the receiving end, demultiplexes the combined signal in the optical fiber into signals of different ITU-T DWDM wavelengths.
