Abstract

Nonlinear interference models for dual-polarization 4D (DP-4D) modulation have only been used so far to predict signal-signal nonlinear interference. We show that including the signal-noise term in the prediction of the effective signal-to-noise ratio in long distance DP-4D transmission improves the accuracy by up to 0.2 dB.

Keywords

optical transmission dual-polarization 4D modulation nonlinear interference signal-to-noise ratio signal-noise term
