1. An optical line terminal (OLT) channel termination (CT) comprising:
- a receiver configured to receive an upstream message from an optical network unit (ONU), wherein the upstream message comprises a correlation tag, wherein the correlation tag represents a unique number that is generated by the ONU for distinguishing an upstream physical layer operation, administration and maintenance (PLOAM) message from the ONU from other PLOAM messages, and wherein the unique number for the ONU changes when the ONU tunes at least one of a wavelength and a power of upstream optical signals transmitted by the ONU;
a processor coupled to the receiver and configured to generate a downstream message based on the upstream message, wherein the downstream message comprises the correlation tag and an upstream passive optical network identification (PON-ID); and
a transmitter coupled to the processor and configured to transmit the downstream message to the ONU.
