Popis: In this work, we analyzed the effects of partial response coding (balance duobinary and dicode coding) in the presence of nonlinear effects. By simulation, we find that the balance duobinary coding is more affected by stimulus Raman scattering (SRS) by an amount of 0.5 dB as compare to dicode coding. So, dicode coding comparatively more tolerance to Raman cross talk in the video Overlay Passive Optical Network (PON). Further in this system 8.3 dB amplification is done by using Raman pump for the data signal to compensate the SRS effect and fiber loss for improving the performance of PON Network.
