Abstract
The present disclosure relates to systems and methods for fast digital signal processor (DSP) optical receiver recovery, namely for optical modems configured on a client side. This approach can be used in optical protection switching (OPS) applications to allow switching between two client links fast, i.e., within 50 ms. A receiver (Rx) digital signal processor (DSP) in an optical receiver includes circuitry configured to detect traffic is interrupted on a current link, enter a holdoff period, and one of i) receive good traffic during the holdoff period and ii) have the holdoff period expire that causes a notification to a host device and retrain to acquire an optical signal.
