In this paper, investigations are made on performance improvement of the optimized SOA preamplifier based system. The effects of order and pulse width RZ super Gaussian pulse are analyzed in terms of receiver sensitivity of optimized preamplifier. It was found that the system is more sensitive when 95ps (Full Width at Half Maximum) FWHM, RZ super Gaussian pulse is used as compared to NRZ pulse. Pre-amplification is an important part of optical communication system. The transmission distance increases as well as receivers with optical preamplifiers are more sensitive as compared to coherent and APD receivers.
