Performance analysis of Erbium Doped Fiber Amplifier at different pumping configurations

Abstract

The fiber amplifier is emerging as a major enabler in the development of worldwide fiber optics networks for high speed communication.Optical fiber is confined with different rare earth doped materials. One of those, are Erbium doped fiber amplifiers (EDFA) which are modeled using two level or three level rate equations. The performance parameters like Gain, Output power and BER are studied which depend on various parameters like Er3+ concentration, fiber length, pump and signal wavelength, pump and signal power etc. Amplifier performance is evaluated using simulation on MATLAB platform. By selecting suitable design parameters desired characteristics of amplifier can be obtained for the particular application.
