The scope of this paper is to analyze the performance of augmented gain EDF amplifier systems by enhancing the stages of EDF amplifier & further by variation in pumping power on designed EDF amplifier system. The design evaluates the performance of the network for a given pattern specifies the design accessibility for the speed enhancement. The Performance of an Optical Communication system can be improved by the use of EDFAs as an Optical Amplifier. Erbium doped fiber amplifier (EDFA) is an important element in DWDM networks. For the present work, we have used EDFA design software tool. The proposed model consists of an input source, isolator, pump source, erbium fiber and WDM coupler. It simulates various characteristics such as amplified spontaneous emission, minimum gain, maximum gain, average gain, noise figure, gain flatness, gain tilt etc. in efficient manner. It confirms the excellent agreement between simulations and results obtained in real EDFA design. And also changing the design parameters on four stages EDF amplifier such as Input Pump Power, the different performance parameters (gain and noise figure) can be optimized without changing the values of isolator, erbium fiber length and WDM.
