Optical wavelength division multiplexing (WDM) system is mostly used for increasing the information carrying capacity than other system. But some factor are deteriorates the performance of all optical system such as chromatic dispersion, polarization mode dispersion, and non-linear effects. In this paper, the 64 channel DWDM optical communication system at 40 Gb/s has been designed and investigated with EDFA as an optical amplifier based on dispersion compensation. Optisystem 7.0 is used for designing and simulation of the proposed system. The three dispersion compensation schemes (pre-, post-, symmetrical-DCF) are investigated & compared. The results of three compensation scheme have been compared in terms of bit error rate (BER) and quality factor. It is observed that both post and symmetrical compensation methods provide better results. This fulfills the requirement such as demand of high capacity and high speed of system.
