Abstract :
Optical communication is a prominent technology for future communication sector because of its low power consumption, high capacity and lower attenuation. It is also affected by the detrimental effects of optical fiber such as dispersion and nonlinear effects. In this paper, the impact of Carrier Suppressed Return to Zero (CSRZ) and Duobinary modulation formats on unfavorable nonlinear Self phase modulation effect of fibers has been analyzed. Modulation formats can have also significant influence on nonlinear effect due to its spectral characteristics. The performance characteristics of this system such as BER and Q-factor are measured with the help of optisystem software. Duobinary gives Q-factor of about 5.57276 and BER of 9.68E-09 even in the case of 40 Gbps bit rate and power 20dBm, whereas CSRZ has the Q-factor of 4.12739 and BER of 1.46E-05 respectively.
