A Design of Digital Chromatic Dispersion Compensator in 200 Gb/s (60 Gbaud, DP-QPSK) Coherent PON

Impact of chromatic dispersion is investigated through demonstrating 60-Gbaud, DP-QPSK transmission for coherent PON. Fixed dispersion compensation is unavoidable in even such a short link, then a partial compensation technique is proposed for cost-effective design. Keywords: Future high capacity and long-reach access networks including Coherent PON, WDM PON, OFDM PON, TWDM-PON and hybrid PON

Abstract

Impact of chromatic dispersion is investigated through demonstrating 60-Gbaud, DP-QPSK transmission for coherent PON. Fixed dispersion compensation is unavoidable in even such a short link, then a partial compensation technique is proposed for cost-effective design. Keywords: Future high capacity and long-reach access networks including Coherent PON, WDM PON, OFDM PON, TWDM-PON and hybrid PON
