Nonlinear compensation of chromatic dispersion for phase- and intensity-modulated signals in the presence of amplified spontaneous emission noise.
We numerically study the evolution of nonsoliton signals in fiber links in the presence of the Kerr effect, chromatic dispersion, and the amplified spontaneous emission of optical amplifiers. Conditions in which the amplified spontaneous emission noise does not deeply affect the signal propagation are found, and the nonlinear Kerr compensation of the distortion induced by the chromatic dispersion is shown.
