Performance degradation due to stimulated Raman scattering in wavelength-division-multiplexed optical-fibre systems

Abstract

The effects of stimulated Raman scattering (SRS) on a two-channel wavelength-division-multiplexed optical-fibre communication system are analysed. For both amplitude and angle modulation the most important effect of SRS is increased loss for the short-wavelength channel, which in the worst case limits the maximum usable transmitter power to ∼ 50 mW.
