Abstract :
We propose combined nonlinear mitigation technique for superchannel transmission. We experimentally demonstrate 3.1 dB performance improvement by optimizing subcarrier power pre-emphasis and applying digital nonlinear compensator with perturbation back-propagation algorithm for four-subcarrier DP-QPSK superchannel in 900 km dispersion-uncompensated transmission.
