In the present work, we have analyzed the effects of dicode coding in a passive optical network based on both wavelength and time division multiplexing (WDM-TDM-PON). By numerical analysis, we observed that network using dicode coding is more tolerant to Group Velocity Dispersion (GVD) as compared to traditional Non-return to zero- on-offkeying(NRZ-OOK)*** degrades the sensitivity of NRZ receiver by 5.5 dB hence limiting the number of users and channel length. With the observations from analysis and results, we suggest the use of dicode coding to double the number of users and increase the length of the network by 20percent in respect to NRZ.
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...

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.
