Abstract

A rigorous small-signal theory for linear and dispersive single-mode fibre communication systems operating at the zero-dispersion wavelength is presented. From this theory, the intensity and frequency noise transmission along the single-mode fibre is assessed. The new theory shows excellent consistency with accurate numerical simulations of intensity and frequency noise spectra after single-mode fibre transmission. Theoretical and simulation results show that fibre transmission at zero-dispersion wavelength leads to intensity and frequency noise spectra at fibre output, similar to intensity and frequency noise spectra, respectively, at the input to the fibre. Accordingly, at zero-dispersion wavelength, second-order dispersion effects on the intensity and frequency noise are irrelevant even for ultra-high bit rates and long-haul fibre links
