Control and management of passive optical network reach extenders

A method for identifying a connection between a reach extender channel termination (RE-CT) and an optical network unit (ONU), the method comprising:

• transmitting, by an optical line terminal (OLT), a ranging bandwidth assignment grant to the ONU via a multi-channel termination reach extender (MCRE);
• retrieving, by the OLT from the MCRE, an ONU identifier (ID) value of the ONU that transmits an upstream burst in a ranging bandwidth during a ranging assignment period;
• and
• identifying, by the OLT, the RE-CT of the MCRE that is connected to the ONU by correlating the ONU ID value of the ONU with the RE-CT that recorded the ONU ID value of the ONU.

An optical line terminal (OLT) comprising a memory configured to store computer-executable instructions, and a processor configured to execute the computer-executable instructions to cause the OLT to:

• transmit a dynamic bandwidth allocation (DBA) grant to an optical network unit (ONU) via a multi-channel termination reach extender (MCRE);
• retrieve, from the MCRE, recorded optical signal power measurements associated with an upstream transmission by the ONU;
• and
• identify a reach extender channel termination (RE-CT) of the MCRE that is connected to the ONU by correlating the recorded optical signal power measurements associated with the upstream transmission by the ONU with the DBA grant.
