SPEED ENHANCEMENT OF NETWORK USING EDFA OPTICAL AMPLIFIER USING OPTICAL PARAMERTERS

Abstract

In this extension up to the fifth stage gives the better results. In this paper an Empirical & pragmentic
implementation is applied using EDFA. The work is presented using different graphs & tabular comparison. 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.
