Abstract
WDM networking based on wavelength add/drop multiplexing and/or wavelength routing offers the following benefits: (1) reduced processing load and latency in intermediate nodes by handling through-traffic optically; (2) significant terminal equipment savings as only a sub-set of wavelengths are terminated and/or generated at each node; and (3) optical transparency that allows a variety of traffic formats and rates to be transmitted over the network without modification to node equipment.
