Abstract
Four Wave Mixing, Stimulated Raman Scattering and Amplified Spontaneous Emission Noise tend to belittle the advantages bestowed by WDM transmission link especially in a link containing inline amplifiers. The Non Linear effects have been related with the intensity and thus most of the work has been directed towards the study of input power to depreciate the limitations imposed by the Non Linearities. In this paper a methodology to decrease the combined effect of SRS, FWM and ASE Noise and to minimize the Bit Error Rate has been suggested by optimizing Inter Amplifier Separation for a 10 Gbps WDM system for link lengths up to 500 Kilometers using Simulation. Optimization of interamplifier separation improves the BER and thus the system length can be extended. Also the nature of ASE and FWM effects has been studied and it has been shown that the system performance is most affected by the FWM effect.
