DWDM MUX DEMUX Modules with 50GHz/100GHz/200GHz channel spacing can be used to combine or separate wavelength channels at standard ITU grid. The DWDM modules passively multiplex the optical signal outputs from 4 or more electronic devices, and send them over a single optical fiber and then de-multiplex the signals into separate, distinct signals for input into electronic devices at the other end of the fiber optic link. Our standard package types of DWDM MUX DEMUX are Field Module ABS Plastic Box, 19" Rack Mount Chassis and LGX Metal Cassette Box.
