Performance Analysis of WDM Network Based On EDFA Amplifier with Different Pumping Techniques

Abstract

A key mechanism for Wavelength Division Multiplexing (WDM) implementation in optical network systems is gain flatness of Erbium-Doped Fiber Amplifier (EDFA). The main intention of this paper is to correct the non-uniformity in the gain for every single channel so that the amplitude gain of the Wavelength Division Multiplexing (WDM) arrangement can be equalized.The software used in this paper is Optisystem 13 so as to accomplish gain flatness of EDFA. The gains are flattened inside 27dB from 1546nm to 1568nm group of wavelength with noise figure < 14dB and we have also seen the effect of various pumping techniques on gain and noise figure. A WDM system arrangement that includes an EDFA is modeled and obtained maximum uniformed gains.
