Integrated performance monitoring (PM); optical layer operations, administration, maintenance, and provisioning (OAM&P); alarming; amplification, and the like is described in optical transceivers, such as multi-source agreement (MSA)-defined modules. A pluggable optical transceiver defined by an MSA agreement can include advanced integrated functions for carrier-grade operation which preserves the existing MSA specifications allowing the pluggable optical transceiver to operate with any compliant MSA host device with advanced features and functionality, such as Forward Error Correction (FEC), framing, and OAM&P directly on the pluggable optical transceiver. The advanced integrated can be implemented by the pluggable optical transceiver separate and independent from the host device.

Performance monitoring (PM); optical layer operations, administration, maintenance, and provisioning (OAM&P); and alarming are provided in optical transceivers, such as multi-source agreement (MSA)-defined modules. The present disclosure provides an optical transceiver defined by an MSA agreement with integrated PM and alarming for carrier-grade operation. The integration preserves the existing MSA specifications allowing the optical transceiver to operate with any compliant MSA host device. Further, the host device can be configured through software to retrieve the PM and alarming from the optical transceiver. The optical transceiver can include XFP, XPAK, XENPAK, X2, XFP-E, SFP, SFP+, 300-pin, and the like. The optical transceiver is configured to frame incoming signals to provide overhead and FEC. The transceiver provides access to all alarms in ITU-T G.709, all Tandem Connection Monitoring (TCM) bytes in G.709, far end monitoring as specified in G.709, loopbacks, historical and real-time PM values, and the like.

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.
