Although dense wavelength division multiplexing (DWDM) technology has been very successful in the long haul market, its penetration into the metro/access market requires new architecture and innovational techniques to integrate the various services into one platform, beyond merely providing bandwidth expansion. The new metro optical platform not only has to reduce the cost associated with optical technology, but also has to provide the flexibility and scalability on demand to meet the special need of unpredictable traffic growth in the metro environment. A metro ring selective WDM architecture with integrated service solutions and simplified multi-layer network management system (NMS) is presented in this paper.
