The increasing demand for 10 Gbit/s Ethernet LAN/WAN services is forcing service providers to consider new approaches for efficiently and cost-effectively transmitting various data types. Optical transport networks (OTNs) are quickly gaining popularity for their ability to transparently provision, transport and manage Ethernet services, among many other data packet services, over the common transport network. Core IP routers are a prime example of this application where multiple 10 Gbit/s interfaces can be terminated in a particular location and transported long distances across the dense wavelength-division multiplexing (DWDM) core optical network. In addition, the integrated packet optical transport networks (POTs), built upon the ITU-T's optical transport network (OTN) standards, are efficiently provisioning, transporting and managing legacy TDM services and data-packet services over the same infrastructure.
