For the radio station, see DWDM-FM. In fiber-optic communications, wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light.t this stage, a basic DWDM system contains several main components: 1  A DWDM terminal multiplexer. 2  An intermediate line repeater is placed approximately every 80â100 km to compensate for the loss of optical power as the signal travels along the fiber. 3  An intermediate optical terminal, or optical add-drop multiplexer. 4  A DWDM terminal demultiplexer. 5  O
