1. A telecommunications monitoring method, comprising:

  • sending an outgoing optical signal from a downstream termination point of an optical fiber, the downstream termination point located within an optical multiplexor box;

    receiving an incoming signal, comprising a reflection of the outgoing optical signal, at the downstream termination point;

    splitting, within the optical multiplexor box, the incoming optical signal into a data optical signal and a test optical signal;

    receiving the test optical signal by an optical time domain reflectometer (OTDR) module within the optical multiplexor box; and

    processing the test optical signal, by the OTDR module, to test for a breach in the optical fiber associated with the outgoing optical signal.
