SYSTEM AND METHOD FOR RE-USING WAVELENGTHS IN AN OPTICAL NETWORK

摘要

A network design that reduces the number of wavelengths needed to support commmunications in a Wavelength Division Multiplexing (WDM) network is disclosed. Wavelengths are reused in isolated sub-networks that do not share common network paths, allowing for the reduction in cost of the WDM equipment supporting the communications in the network.
