A Novel, Multi-Service Add-Drop-Multiplexer Architecture for Access and Backhauling Applications With 4.3Gbit/s Line Rate

An ADM architecture with 4.3 Gbit/s interface representing the current cost/ bandwidth optimum for GE services is presented. It offers high scalability, interface protection, and drop-and-continue support and is thus optimised for GE access and backhauling applications.
