Reconfigurable Add/Drop Multiplexer Design to Implement Flexibility in Optical Networks

Abstract

Reconfigurable optical add-drop multiplexer (ROADM) is a key network element enabling flexible handling of wavelengths. Its architecture allows for remote traffic provisioning at the wavelength level in network node, better utilization of transmission bandwidth, operation cost reduction, simplification of network design and implementation. In this talk we present recent results on the investigation of ROADM architecture, components and technologies. The study considers physical and networking aspects including modeling and simulations for optimization of the switching node
