ABSTRACT

ABSTRACT: In this paper the effect of dispersion on the transmission distance has been demonstrated. Chromatic Dispersion in signal increases as length of optical fiber increases. This limits the performance of a system. Three dispersion compensation techniques are used to compensate the dispersion in 40Gbps OTDM system: pre-, post- and symmetrical over an Alcatel Dispersion Compensated Fiber (DCF) having dispersion 8ps/nm-km. These three techniques pre, post and symmetrical are compared. With pre- dispersion compensation technique, maximum distance travelled by a signal was 572 km. With Post- dispersion compensation technique, maximum distance travelled by a signal was 616 km. But the best results were observed in symmetrical dispersion compensation technique where maximum distance travelled by signal is 704 km with Q-Factor 7.9. All the results are gained at a wavelength of 1552.52 nm.
