Abstract

Reconfigurable Optical Add / Drop Multiplexer is a subsystem of All Optical Networks. In this paper we analyze the routing performance of ROADMs at peak traffic using Pascal distribution model. To evaluate wavelength routing capability of ROADMs of various architectures in dynamic optical network, a theoretical routing power model is considered. With simulation results, the routing power and blocking probability have been evaluated to achieve better performance and flexibility.
