“…The optical spectra of operations extend from Short (S)‐band (1460–1530 nm), Conventional (C)‐band (1530–1565 nm), and long L‐band (1565–1625 nm). Most of the EDFA systems today operate in the C‐ and L‐band . But such systems require gain equalizing filters (GEF) to obtain gain uniformity .…”

In the letter, a high gain‐naturally flattened L‐band erbium‐doped fiber amplifier (EDFA) is demonstrated. The system uses two bidirectionally pumped lasers for exciting Er3+ in three cascaded fiber amplifiers. The maximum gain of ∼36.4 dB and equalized gain of over 26 dB in the absence of any gain flattening filter with ∼2.5‐dB variation over 35 nm (1572–1608 nm) was obtained. Studies for varying amplifier lengths; signal power and pump powers have also been reported. The proposed EDFA has a noise figure below 5 dB and was found to be stable at extreme temperatures. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:2053–2055, 2014

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 EDF A 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.
