A Colorless and Directionless (C&D) ROADM architecture has empowered today's networks with the much needed flexibility and scalability to handle the unpredictable high bandwidth demands, provide any-to-any connectivity and provision new services without disrupting the existing ones. In this paper, we realize the C&D ROADM architectures using(More)
Service Providers are constantly searching for means to reduce costs, generate new revenue streams and increase their competitive advantage. The migration to Colorless and Directionless mesh architecture will enable the Service Providers to realize new scalability, availability, flexibility and dynamic reconfigurability demands for optical networks. But(More)
Next generation of optical networks will witness the advent of flexible spectrum/grid reconfigurable optical add drop multiplexers (ROADMs). The pass band of these next generation ROADMs can be varied depending on the spectral width of the incoming signal. With the pass band becoming a variable, spectrum allocation becomes an added constraint to the(More)
