Linear Approximation Method for Minimising SRS Effect in All-Optical WDM Fiber Optic Systems

Abstract

A novel “Linear Approximation Method (LAM)” has been developed and suggested for the estimation of optical powers to be launched at different wavelength channels to minimise the variation in the system performance at different wavelength channels due to Stimulated Raman Scattering (SRS) in Wavelength Division Multiplexed (WDM) fiber optic systems. A 2000 km long point-to-point all-optical WDM fiber optic link having sixteen channels (each channel has a data rate of 2.5 Gbits/sec) with inter-channel separation of 1nm has been simulated to study the effectiveness of the LAM. The efficiency of LAM has also been examined for different inter-amplifier spacing and different levels of total optical power launched into the simulated system.
