摘要

Geometric shaping with many-to- one mapping is experimentally demonstrated for bit-interleaved coded modulation (BICM) coherent optical fiber system. Up to 0.75 bits/2D symbol of gain are achieved w.r.t. conventional BICM with fixed FEC engine and modulation format over wide range of distances with arbitrarily small rate step.
