摘要：

This paper reflects the analytical study of dense wavelength division multiplexed optical network with different number of channels at various channel spacing in order to achieve higher data rates by means of few advanced modulation schemes. Bit error rate and quality factor are being analyzed with the variation in number of channels, channel spacing and transmission length of fiber. Advanced modulation schemes being compared here are carrier suppressed return to zero (CSRZ), duobinary return to zero (DRZ), modified duobinary return to zero (MDRZ), 33% differential phase shift keying (33% DPSK), 66% DPSK and differential quaternary phase shift keying (DQPSK). It is keenly observed that CSRZ scheme with 100GHz channel spacing serves best performance in terms of max. Q factor, min. BER and maximum transmission coverage upto 4,000km for 16 and 32 channels DWDM system since CSRZ is high tolerant to nonlinear effects. On the other hand, MDRZ scheme with 75GHz channel spacing exhibits transmission coverage upto 4,000km and 4,500km for 16 and 32 channels respectively, but with degraded signal due to effect of inter symbol interference (ISI). © 2016 by De Gruyter.
