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.
