  • Abstract
    We propose a new 4D coded modulation format, 64SP-12QAM, with same SE as PM-8QAM and straightforwardly-switchable with PM-16QAM. We experimentally demonstrated over 0.2 dB better sensitivity for 64SP-12QAM compared to PM-8QAM, enabling a transmission reach extension to 6,000 km at 6b/s/Hz.
