Abstract

In an Erbium Doped Fiber Amplifier the gain and noise figure are strongly dependent on fiber length. This paper presents simulative studies on Length Dependent Gain and Noise Figure Analysis in a Dual Stage L-Band EDFA WDM Network. A high gain of 42dB was obtained at 1562nm wavelength with a total EDF (EDF-I 5m and EDF-II 5m) length of 10m and total pump power (980nm pump and 1480nm pump) of 270mW. Low noise figure of less than 4.7dB occurs in the entire wavelength range (1561nm-1617nm). A high Power Conversion Efficiency of 48% and Quantum Conversion Efficiency of 60% has been obtained. This paper also studies the variation of gain and noise figure with varying temperature and fiber length. The configuration discussed in this capable of successfully implemented for L-band amplification with high gain and low noise figure.
