Lower bounds on the capacity of optical fiber channels are derived by using a correlated phase-and-additive-noise (CPAN) mismatched model that is motivated by perturbing the nonlinear Schrödinger equation with small nonlinearity. Both the phase and additive noise processes are Gauss-Markov. The CPAN model characterizes nonlinearities better than existing models in the sense that it achieves larger information rates.
