TI - Nonlinearity Mitigation for Multi-channel 64-qam Signals in a Deployed Fiber Link Through Optical Phase Conjugation N2 - We report nonlinearity mitigation of two 64-QAM signals, tested in a WDM environment, through mid-link optical phase conjugation. Efficient reuse of signal bandwidth and a Q-factor improvement of more than 1.7 dB is demonstrated in a 400 km installed fiber link.
