ROADMs for metro networks

As business and residential broadband services continue to grow, capacity demands on the transport network are also growing dramatically. CWDM and DWDM technologies meet the bandwidth requirements for metro networks with inherent scalability and native support for high-growth packet services. With the deployment of DWDM comes also the need for optical bypass with OADMs to lower network costs. The key attribute of optical bypass in the transport network is the means to implement cost effective multi-point connectivity in DWDM ring or mesh networks without unnecessary Optical-to-Electrical-to-Optical (OEO) transitions. ROADM implements optical bypass with particular benefits in ease of use and deployment, fitting also into existing operational deployment models.
