PERFORMANCE EVALUATION OF DECISION FEEDBACK EQUALIZATION (DFE) BASED DISPERSION COMPENSATOR BY VARYING FORWARD TAP SPACE & ADAPTIVE STEP SIZE IN THE SCENARIO OF 4X10-GBIT/S WDM SYSTEM

Abstract

With the advancement of technology, the demand for bandwidth increases exponentially with time. Hence, optical fiber communication becomes the optimum choice for backbone networks. As the efficiency of the optical system is limited by congenital parameters such as chromatic dispersion. So, in this work, we have evaluated the ability of electronic equalization scheme reduce the CD (chromatic dispersion for an optical communication system capable of transporting 4 channels at 10 Gbps line rate over a distance of 30km. Further, we compare the performance of decision feedback equalizer with two different configurations.
