Analysis on Dispersion Compensation with DCF based on Optisystem-A Review

The most commonly used dispersion compensation fiber (DCF) technology is studied. Three schemes (Pre-compensation.post-compensation, mix-compensation of Dispersion Compensation methods for 40 Gb/s non-return to Zero link using standard and dispersion compensated fiber through FBG compensator to optimize high data rate optical transmission. Objectives is to increase the quality factor, fiber length and better eye opening in eye diagram using different modulations techniques. The simulation results are validate by analyzing the Q-factor and Bit error Rate(BER) in the numerical simulator. A fiber brag grating (FBG) is one of the most important and applicable component in an optical communication system. The use of chirped FBG has been studied as a dispersion compensator in an optical communication system. The simulation Results are validated by analyzing the Q-factor. According to test, when Q=6, the BER is about 10-9; when Q=7,the BER is about 10-12.Input power is taken as 9-10 db,Thecorresponding BER is better. It is observed that the symmetrical-compensation scheme performs better than pre-, post -compensation schemes for 8x40 Gb/s wdm system.
