Cross Polarization Modulation (XPolM) Compensation for Submarine Upgrade Links using DP-8QAM



We propose a method of XPolM compensation suitable for submarine upgrade systems, and experimentally validate performance for a 70 x 192 Gb/s DP-8QAM system. The method improves the Q-factor by 0.16dB and outperforms the conventional NPCC by 0.12dB.
