Open full text 1 citations

Abstract

The erbium doped fiber amplifier (EDFA) is one of the most important devices in the present optical communication and measurement system. However, the problem on parameters optimization of EDFA is always an open issue. Aim to obtain the output characteristics quickly and flexibly, in this article, we model the operation of an EDFA system by simulation. The numerical results show that the output spectrum of EDFA with various parameters. And through analyzing the performance in terms of gain, flatness and noise, the optimal pumping power and the length of EDF are determinate.
