Design Performance of High Speed Optical Fiber WDM System with Optimally Placed DCF for Dispersion Compensation

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.
