Performance Analysis Of Dispersion Reparation Using Dispersion Compensation Fiber At 100 Gb/S For 120Km Using Single Mode Fiber

Since the data traffic is increasing day by day so there is a need of high capacity long distance optical links.As the data transmission increases over a long distance,signal gets deteriorated.This is because of the pulse widening known as dispersion and it should be compensated for better results.Different compensation techniques are available like FBG, EDC and DCF. Hence, in this paper we have used DCF as dispersion compensator at a bit rate of 100Gbps over a distance of 120km.ThreeDCF schemes i.e. pre,post and symmetric are proposed and investigated at different input power levels (1-10dBm).The results of these three schemes are then compared in terms of quality factor and bit error rate.Post compensation scheme of DCF exhibits low bit error rate and high quality factor.Thus, making it a best technique for dispersion compensation using DCF..
