We demonstrate the transmission of 3 × 20 Gbaud PAM4 signals over a 360 km, field-deployed, amplified transmission link. We compare dispersion compensation using optical phase conjugation (OPC) to dispersion compensating fibre (DCF) and find an improvement in the received bit error ratio of an order of magnitude using our OPC implementation.
