In this paper, a numerical analysis of impairments due to PMD and PDL on system performance is investigated in High Speed Optical Communication System. Optical Polarization has pronounced effect on signal quality. Thus there is a need to control the State of Polarization (SOP). Pulse Broadening can be controlled by launching the light signal in particular State of Polarization such as Linear and Circular. Two types of Pulses such as Chirped Gaussian and Supergaussian pulses are launched at different SOP into the optical fiber and it is found that maximum pulse width reduction is achieved when the pulse is at Circular SOP than that of Linear SOP. Also results clearly show that with PMD and PDL, pulse width ratio of Chirped Gaussian pulse is much reduced than that of Chirped Supergaussian Pulse.
