OPTICAL TRANSPORT NETWORK HIERARCHY FOR FULL TRANSPARENT TRANSPORT OF DATACOM AND TELECOM SIGNALS

摘要

The present invention provides an Optical Transport Network (OTN) hierarchy that supports full transparency for both Ethernet and Telecom signals. The present invention defines new rates and mapping/multiplexing methods to adapt transparent 10 Gigabit Ethernet (10 GBE) (255/238 and 255/237) and 10 Gigabit Fibre Chanel (10 GFC) (255/237) to Optical Channel Transport Unit-3 (OTU3) at a higher rate. Additionally, the present invention defines new rates and mapping/multiplexing methods to adapt future transparent 100 GBE into an Optical Channel Transport Unit-4-extended (OTU4e) which is an OTU4 at a higher rate to support full transparency.
