WDM

Wavelength Division Multiplexers (WDM) are passive devices that combine light signals with different wavelengths, coming from different fibers, onto a single fiber. They include dense wavelength division multiplexers (DWDM), devices that use optical (analog) multiplexing techniques to increase the carrying capacity of fiber networks beyond levels that can be accomplished via Time Division Multiplexing (TDM). With DWDM, different wavelengths of light can transmit multiple streams of information along a single fiber with minimal interference. They are deployed as point-to-point, static overlays for TDM networks and represent a precursor to optical networking. In reducing the cost of transport, dense wavelength division multiplexers require fewer electrical generators and share a single optical amplifier over multiple signals.
