Performance Analysis Of Different Dispersion Compensation Schemes In A 2.5 Gbps Optical Fiber Communication Link

ABSTRACT In this paper investigation has been done on the performance analysis of different schemes of dispersion compensation using dispersion compensating fiber DCF namely post pre and symmetric compensation at a particular power level of transmitting laser using different modulation formats such as NRZ modulation format at 2.5 Gbps data rate. The value of eye height Q- factor BER was observed in every case using help of eye diagrams. It was observed that symmetric compensation showed best performance with the highest value of Q- factor whereas pre compensation showed worst performance among the three schemes with the lowest value of Q- factor.
