Abstract
This work is proposed to examine modified duobinary return to zero modulation in DWDM long haul communication system. In this framework we simulate 32 channels each channel data rate is 40 Gbps multiplexed with the channel spacing 80 GHz, 90 GHz and 100 GHz to perceive 1.2 Tbps data. This data completed transmission Distance over 250 KM by utilizing scattering remuneration strategy. This 40 Gbps data is encoded by utilizing Mach Zehnder modulator (MRZ) inferred by CW laser of power − 10 dBm, − 5 dBm, 0 dBm, 5 dBm, 10 dBm. In the system analysis, we use modified duobinary return to zero (MDRZ) in the DWDM communication long haul system.
