MONET WDM network elements

Lucent has developed and implemented three different types of network element: the WSXC (wavelength selective cross-connect), the WADM (wavelength add/drop multiplexer) and the WAMP (wavelength amplifier) on single mode fiber (SMF). This article describes the most significant aspects of systems engineering, systems architecture, advanced components, switch control algorithms, advanced techniques for optical monitoring and optical backplane of the Lucent advanced optical network elements under development to realize the MONET (Multiwavelength Optical NETworking) program vision.
