1. An optical communications network comprising:
a plurality of optical data links comprising a plurality of data channels; and
a system communicatively coupled to the plurality of optical data links, the system comprising a processor and memory storing executable instructions that configure the system to perform operations comprising:
determining a pre-forward error correction (preFEC) bit error rate (BER) of a selected optical link;
obtaining a FEC Detected Degrade (FDD) threshold, FEC Excessive Degrade (FED) threshold, and FEC limit threshold for the selected optical link, wherein the FDD threshold is less than the FED threshold and the FED threshold is less than the FEC limit threshold;
asserting a link down condition when the preFEC BER rises above the FEC limit threshold; and
de-asserting the link down condition when the preFEC BER falls below the FED threshold.
