Patent abstract

The present disclosure provides an optical transceiver, method of mapping, and method of management utilizing a plurality of Optical Channel Transport Unit layer k (OTUk) links to form an aggregate signal, such as, for example, 10 OTU2s to provide a single 100 Gigabit Ethernet (100 GbE) signal. Specifically, the present invention enables use of existing circuitry and methods at lower speed signals, e.g. 10 G, to support higher speed aggregate signals, e.g. 100 G. The present invention may be utilized to support carrier-grade OTN applications with optical transceivers such as, for example, pluggable optical transceivers. In an exemplary embodiment, the present invention includes a method which receives a plurality of signals, frames each of the plurality of signals into an OTUk frame, and manages/monitors each of the plurality of signals in an OTUk frame in the aggregate.
