1. A method of monitoring an optical fiber with at least one optical transceiver having an optical time domain reflectometry (OTDR) and/or optical frequency domain reflectometry (OFDR) function that is disposed to couple to the optical fiber, the method comprising:

  • connecting an optical transceiver to a network terminal, the optical transceiver having OTDR and/or OFDR function and the network terminal is configured to read information from the optical transceiver;

    coupling the optical fiber to the optical transceiver;

    performing data communications on a same wavelength with the optical transceiver;

    performing OTDR and/or OFDR function on the same wavelength with the optical transceiver responsive to a disruption in the data communications;

    gathering measurements from the OTDR and/or OFDR function to determine at least one fault on the optical fiber;

    storing the measurements in the optical transceiver;

    reading the stored measurements from the optical transceiver to the network terminal, andreporting by the network terminal of the at least one fault on the optical fiber.
