Cost-effective Metro Optical Network Architectures

We investigate cost-effective metro-optical network solutions using different building-blocks: full-fabric OTN switching, paired muxponder add-drop multiplexing (ADM), single muxponder ADM, and pure muxponder (no-ADM), and show that paired muxponder ADM functionality can give optimal results without the additional costs of full-fabric OTN switching.
