DWDM module is a passive optical multiplexer/ demultiplexer designed for metro access applications that represent the state of the art in fiber optics design. This MUX/DEMUX module multiplexes and demultiplexes forty DWDM wavelengths of 100GHz channel spacing into a ring or point-to-point network.Optico 100GHz dense wavelength division multiplexer (DWDM) provides ITU channel center wavelength, low insertion loss, high channel isolation, wide pass band, low temperature sensitivity and epoxy free optical path . It can be used for wavelength add/drop in telecommunication network system.
