Abstract: Embodiments described herein provide for improved detection and correction of a polarity mismatch/swapped fiber without requiring manual intervention. The optical transceivers and methods provide improved detection and correction by determining receive (Rx) optical signals for an optical connection are not detected in a Rx path in an optical transceiver and, upon detecting the crossover Rx optical signals in the Tx path, implementing a crossover correction scheme in the optical transceiver to enable optical connections.
