Abstract

In this paper, simulative performance analysis for different modulation formats like NRZ rectangular, NRZ raised cosine, RZ soliton, RZ super gaussian, RZ raised cosine and RZ rectangular, has been demonstrated and analyzed at each node with varying bit rate. It is seen that overall NRZ modulation is performing better among all modulation driving schemes. It is also observed that by using RZ soliton format system can exist up to 90 dB of insertion loss of optical add drop multiplexers with bit rate upto 10 Gbit/s. For 10 Gbit/s of bit rate quality factor drops off below 15 dB after 85 dB of insertion loss for RZ soliton.
