Impact of multipath interference on Raman amplifiers based system performance

Research output: Contribution to journalArticle

Abstract

A novel multipath interference (MPI) model that is independent on modulation format, MPI crosstalk level, optical and electrical filter choice is proposed in this paper. MPI and ASE noise impact on receiver performance is considered taking into account the transfer functions of optical and electrical filters, intersymbol interference and receiver noise. ASE noise components are assumed to be colored Gaussian with power spectral density determined by EDFA output filter, while the components of multipath interference is colored Gaussian with the power spectral density determined by the signal spectrum. The comparison with widely used Gaussian crosstalk model is made and shown that Gaussian crosstalk model gives satisfying results just for low crosstalk level values. Also Gaussian crosstalk model is valid just for NRZ, rectangular shape of optical filter transfer function and integrate and dump electrical filter.
