We revisit the problem of estimating the nonlinear channel capacity of fiber-optic systems. By taking advantage of the fact that a large fraction of the nonlinear interference between different wavelength-division-multiplexed channels manifests itself as phase noise, and by accounting for the long temporal correlations of this noise, we show that the capacity is notably higher than what is currently assumed. This advantage translates into nearly doubling of the link distance for a fixed transmission rate.

  12. With system parameters similar to those used for evaluating the capacity in [3] and assuming, for example, a 500 km link, the phase has been shown to be nearly constant on the scale of a few tens of symbol durations [9].
