1. A first optical fiber panel unit, comprising:

  • a plurality of fiber input ports, each configured to connect to a different one of multiple optical fibers, wherein each fiber input port comprises;

    a connector port configured to connect to a respective fiber panel optical path,an optical tap configured to couple to the respective optical path, anda photo-detector coupled to the optical tap and configured to;

    detect optical signals carried over the respective optical path, andproduce electrical signals that correspond to the detected optical signals; and

    a telemetry circuit, which includes an optical port connected to a fiber link that connects to a second optical fiber panel unit at another location in an optical network, and is configured to;

    analyze the electrical signals that correspond to the detected optical signals of each respective optical path,determine at least one of a loss of signal (LOS) or loss of light (LOL) at each of the fiber input ports based on the analysis of the electrical signals, andsend a report, via the optical port to the second optical fiber panel unit, including a status of the first optical fiber panel unit and any determined LOS or LOL at each of the plurality of fiber input ports.
