XPM and SBS nonlinear effects on MLSE with varying uncompensated dispersion.
We investigate the performance of a maximum likelihood sequence estimation (MLSE) receiver at 10.7 Gb/s in the presence of two optical nonlinear impairments, cross-phase modulation (XPM) and stimulated Brillouin scattering (SBS). We find that the tolerance to both nonlinearities decreases with larger levels of uncompensated dispersion. Our results also suggest that the MSLE receiver loses its linear regime advantage in comparison to a standard receiver at some dispersion levels in the presence of the nonlinear effects. We demonstrate that long uncompensated links up to 160 km may show better tolerance to the nonlinear effects with a lower dispersion fiber when using an MLSE receiver.
