CWDM Mux / Demux (Coarse Wavelength Division Multiplexing) is a low-cost WDM transmission technology for the metropolitan area network access layer. CWD Mux / Demux can increase network capacity by transmitting multiple data channels with separate optical wavelengths (1270nm to 1610nm) on the same single fiber.
