Abstract:
In some embodiments, an apparatus comprises an optical transponder which includes a processor, an electrical interface and an optical interface. The processor is operatively coupled to the electrical interface and the optical interface. The optical interface is configured to be operatively coupled to a plurality of optical links and the electrical interface is configured to be operatively coupled to a router such that the optical transponder is configured to be operatively coupled between the plurality of optical links and the router. The processor is configured to perform pre-forward error correction (FEC) bit error rate (BER) detection to identify a degradation of an optical link from the plurality of optical links. The processor is configured to make modifications to packets designated to be transmitted via the optical link in response to the degradation being identified such that the router is notified of the degradation of the optical link.
