Abstract
A signaling scheme is presented which effectively combines a class of power-efficient four-dimensional modulation formats with forward error correction using a tailored two-stage coded modulation scheme. In a 400ZR system experiment, a 0.8-dB gain in required OSNR over DP 16-QAM at 60 GBd is demonstrated.
