Abstract

Midlink optical phase conjugation (OPC) based on four wave mixing (FWM) in semiconductor optical amplifier (SOA) can be used to compensate for the nonlinearity phase noise, Gordon-Mollenauer effect, in CO-OFDM long-haul systems. Simulation of 40Gb/s CO-OFDM systems without optical dispersion compensation is presented and the Q factor can be increased by >6 dB through OPC.
