Abstract :
High-order QAM offers the high spectral efficiency and high capacity. PDM-64QAM with single-carrier frequency-division-multiplexing (SC-FDM) enhanced by pilot-tone-based phase noise compensation is proposed and shown to achieve high-capacity transport with 400Gb/s-class high speed channels.
