Ultra high capacity 1.28 Tbps DWDM system design and simulation using optimized modulation format. ![]() It is observed that the distributed compensation technique outperformed rest of the techniques and supported maximum coverage distance towards 19,200 km for Q-factor of 6.96 and corresponding BER of 1.72E-12 in comparison to sym-1 for 14,400 km at Q-factor of 6.95 with BER of 1.77E-12 and sym- km at Q-factor of 7.13 with BER of 4.83E-13 whereas both pre- and post-compensation techniques supported 7200 km at Q-factor of 7.21 with BER of 2.71E-13 and Q-factor of 7.18 for BER of 3.53E-13, respectively.Īuthor contributions: All the authors have accepted responsibility for the entire content of this submitted manuscript and approved submission.Ĭonflict of interest statement: The authors declare no conflicts of interest regarding this article.ġ. We have used Gaussian filters (GFs) at both ends before multiplexing and after de-multiplexing for ensuring channel severance to elude the cross-talk and inter-symbol interference. The performance evaluation criteria of the proposed system for 50 GHz frequency spacing between the adjacent channels at 0 dBm launched power and various transmission distances with the increment of 2400 km are kept as BER, Q-factor and eye-diagrams. In this research article, we have made the comparative performance analysis towards the ultra-transmission capacity of 5.12 Tbps for DWDM long-haul system using spectrally efficient multilevel DQPSK modulation format under the influence of Kerr’s nonlinearities with DCF based distributed, pre-, post and two types of symmetrical compensation techniques.
