Power budget improvement for coherent optical — OFDM access upstream transmission using TCM with constellation shaping

Abstract

Power-budget improvement to support more Optical Network Units (ONU) is the most significant issue for passive optical access networks. Investigation on Trellis coded modulation for multi-user phase noise channel is conducted to improve the power budget for CO-OFDMA uplink transmission. The power budget is doubled enabling 37.4-km CO-OFDMA upstream transmission supporting 32 ONUs. To our best knowledge, this is the first field trial of optical access network using coherent optical - OFDM technique.
