Claim 15:
16. A method of identifying a source of a degradation within a passive optical network (PON), the method comprising:
detecting that an optical line terminal (OLT) or a first optical fiber received by the OLT and via which optical signals are delivered to a last mile termination unit is the source of the degradation within the PON when one or more differences between a drift over time of an optical profile of a segment of the PON and respective drifts over time of respective optical profiles of one or more other segments of the PON that respectively include the OLT or the last mile termination unit are within respective predefined tolerances, the segment of the PON including the OLT and the last mile termination unit, and the last mile termination unit disposed at a location serviced by the PON;
detecting that the last mile termination unit or a second optical fiber received by the last mile termination unit and via which the optical signals generated by the OLT are received at the last mile termination unit is the source of the degradation within the PON when the one or more differences are not within the respective predefined tolerances; and
providing an indication of the detected source of the degradation to a recipient application or device.
