Abstract

Erbium-doped fiber amplifiers(EDFAs) are very attractive devices for single-mode fiber communication systems operating in the 1.55 μm wavelength band. [1] The main advantages of EDFAs are polarization-insensitive high gain, high amplification efficiency, low insertion loss, low noise and wide bandwidth. [2] There are two important parameters to evaluate EDFA’s performance; an energy conversion efficiency and a gain coefficient.
