In this paper, the design of dispersion compensated DWDM system using Hybrid Amplifier is presented. The evolution of fiber-optic systems in communication bears the properties of enhanced bandwidth, enormous capacity and robustness. However from the practical point of view, the vast benefits of DWDM system cannot be fully utilized. The main performance degraders include linear factors and non-linearity metrics. Among these undesirable parameters the dispersion and loss of optical fiber itself are most critical. So the reduction and elimination of these unwanted factors becomes essential to accomplish optimum utilization of the system. The evolution of EDFA has significantly miniaturized the loss of optical fiber. However dispersion is severely affecting the performance of fiber-optic systems. The fed light signal is severelydistorted by dispersion, due to which signal quality, data rate and distance covered are greatly lessened. Therefore the techniques for effectively controlling the dispersion become burning concern in these systems. Optisystem 11. 0 is used for designing the proposed system and carries out simulations. Chirped FBG and EDFA –RAMAN hybrid amplification instead of EDFA alone is used to achieve acceptable signal at the receiver withimproved Q-Factor and BER. Special focus is given to CD which is compensated using chirped FBG.
