The dispersion effects are usually equalized DSP electronically by a linear filter in the coherent receiver. Such a linear optical link can be well described by an arbitrary white Gaussian noise (AWGN) channel, the capacity of which is unbounded with the signal power. However, the fiber Kerr nonlinearity introduces signal distortions, and greatly complicates the transmission modeling. The nonlinear signal propagation in the fiber is described by a nonlinear partial differential equation, the NLSE, which includes dispersion, attenuation, and nonlinearity.
