Performance analysis and implementation of different pumping techniques on an EDFA amplifier

A basic mechanism for Wavelength Division Multiplexing (WDM) implementation in optical network systems is the gain flatness of Erbium-Doped Fibre Amplifier (EDFA). The main intention of this paper is to correct the performance and 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 simulator used in this paper is Optisystem 14 so as to make successful 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 effects of various pumping techniques on gain and noise figure. A WDM system arrangement that includes an EDFA is modelled and obtained maximum uniformed gains.
