A PIECE WISE LINEAR SOLUTION FOR NONLINEAR SRS EFFECT IN DWDM FIBER OPTIC COMMUNICATION SYSTEMS

M. L. SINGH, I. S. HUDIARA

Abstract


Stimulated Raman Scattering (SRS) is one of the significant nonlinear effects in dense wavelength division multiplexed (DWDM) based fiber optic communication systems. For tackling this problem accurate evaluation of amplification and depletion of optical power at different wavelength channels due to SRS effect in DWDM fiber optic systems is required. In this paper we have presented a method for evaluating SRS effect taking into account both the pump depletion and wavelength dependence of fiber attenuation coefficient. The novelty of our method is that the nonlinear problem of SRS has been solved in a piecewise linear manner, i.e., the nonlinear problem is divided into small linear steps. In addition to this wavelength dependent fiber loss coefficient is considered, which is assumed wavelength independent in the analytical models available in the literature. Also an algorithm has been developed to increase the step size from 100 meters to 1km without sacrificing the required accuracy. This ten time increase in the step size has led to a significant reduction in the overall processing time, which is very useful for the simulation purpose.
