Parameter Optimisation for Ultra-Wideband Optical Networks in the Presence of Stimulated Raman Scattering Effect

Abstract

This paper studies the effects of channel launch power and topology parameters on performance for ultra-wideband optical networks in the presence of stimulated Raman scattering (SRS). Results exhibit significant throughput improvements for optimised per-channel launch power allocation over conventional uniform power allocation. Furthermore, the impact of network structural features on performance is investigated and a significant increase in throughput and a reduction in fibre installation cost are achieved by optimising network topology for two real world core networks.
