Abstract
Properties dependent on the signal polarization state, such as polarization dependent loss (PDL) and polarization hole burning (PHB), can limit the performance of long distance in-line amplifier systems [1],[2]. Polarization-mode dispersion (PMD) of transmission optical fibers is an important factor, but its effect has been evaluated only in the linear regime [3]. PMD may enhance signal waveform distortion in combination with the self-phase modulation (SPM) caused by fiber nonlinear refractivity. This paper discusses the combined effect of PMD and SPM on in-line amplifier systems by means of numerical simulations.
