Joint SPM Compensation for Inline-Dispersion-Compensated 112-Gb/s PDM-OFDM Transmission

We show numerically that the nonlinear tolerance of a 112-Gb/s polarizationdivision-multiplexed coherent optical OFDM signal in inline-dispersion-compensated transmission can be substantially improved by a joint self-phase-modulation compensation scheme, particularly when optimized dispersion maps are used.
