Abstract

Diverse factors like chromatic dispersion, polarization mode dispersion, attenuation, non-linear effects, second order and third order dispersion impress limit on the performance of all the optical fiber networks. Dispersion compensation fiber are being used in this paper , we projected three techniques (pre, post, and mix-compensation of dispersion compensation) of dispersion compensation methods for non-return to zero links using standard for high date rate optical transmission system. The performances have been compared on the basis of parameters such as Q factor, bit error rate (BER), eye height and threshold level at the receiving end. The simulation model of the WDM system using the software Optisystem 12. 0 is presented according to the above principle. It is observed that the post-compensation technique performs better than pre-, mix-compensation technique for 40 Gb/s in the WDM system
