Paper Details

Major challenge faced by today'stelecommunication is the increasing demand of bandwidthand data rates. In order to expand the capacity of the opticalsystem, it has accelerated the development of high capacityDWDM links. There are some barriers in DWDM related todata rate and capacity. These barriers are linear andnonlinear effects. Out of these barriers, linear effects such asattenuation and dispersion can be easily compensated usingsoliton and dispersion compensating fiber but there is anaccumulation of nonlinear effects. The nonlinear effects occurin optical system are Self-Phase Modulation (SPM),Stimulated Brillouin Scattering (SBS), StimulatedRaman Scattering (SRS), Cross Phase Modulation(XPM), And Four-Wave Mixing (FWM). Out of whichSBS and SPM is examined in single channel linkwhereas SRS, XPM and FWM is introduced in multichannel linkIn this paper optical link of different number of data channelsis studied using MDRZ modulation scheme at various inputpower levels. Paper shows the simulated performance analysisof the impact of Cross Phase Modulation and Four WaveMixing on DWDM optical network. The analysis is done onthe basis of Q-factor, Optical Spectrum and Eye Diagram.Performance of link deteriorates as the input power and thenumber of data channels increases.
