Improved nonlinearity precompensation for long-haul high-data-rate transmission using coherent optical OFDM.
We show that the performance of precompensation of fiber nonlinearity in coherent optical OFDM systems operating at up to 60 Gbps/polarization can be improved by electrical filtering the precompensation signal. The optimal filter bandwidth is related to the FWM efficiency spectrum when dispersion is considered.
