Nonlinear noise characterization in highly dispersive optical transmission systems

This paper reports an analytical investigation, confirmed by numerical simulations, about the nonlinear noise impact on the performance of single-channel systems adopting generic modulation-detection formats and operating in long links with both managed and unmanaged dispersion compensation. Such a noise contribution is analyzed in terms of a pulse nonlinear interaction length, that depends on the link dispersion characteristics and on the modulation-detection format.
