“…EDFA provide high gain in 1530-1560nm wavelength band region, here erbium ions emitted band energy is greater than the energy absorbed and in this range gain bandwidth is narrower. The emission and absorption of the energy EDF according to Figure 3 of the spectrum, where the highest gain peak of EDFA near 1550nm, hence the gain obtained clears that the operating wavelength is 1550nm [7][8] [9].…”

In the present work, gain of EDFA (Erbium Doped Fibre Amplifier) and YDFA (Ytterbium Doped Fibre Amplifier) are analyzed based on their performance parameters. The effects of pump laser power, length of doped fibre that used for amplification and the wavelength of the input signal on the gains of the optical amplifiers is examined. EDFA exhibits maximum gain of 48db around 1550nm regions with pump wavelength of 980nm (pump power=10Watt, EDF length=30m), on the other hand YDFA exhibits maximum gain of 62db around 1030nm regions with pump wavelength of 975nm (pump power=5Watt, YDF length=8m). The ANALYSIS shows that the gain of YDFA is superior to that of EDFA for short fibre length.

“…Firstly, the pump power is kept constant and input signal power is varied and secondly the input power is kept constant and Pump power is varied.Semmalar.S et al [2] simulated EDFA of different lengths with an influence of pump power for optimizing gain and noise Figure. The gain spectrum and the noise figure spectrum of EDFAs can vary from amplifier to amplifier even with the same core composition.…”

The scope of this paper is to analyze the performance of augmented gain EDFA systems using Single and Multiwavelength Input sources. The Performance of an Optical Communication system can be improved by the use of EDFAs as an Optical Amplifier. Erbium doped fiber amplifier (EDFA) is an important element in DWDM networks. We can achieve a flat gain spectrum by modeling the dynamic characteristics of an EDFA. This paper presents basic EDFA model operating on single (1550nm) and multi (1520-1610) nm wavelength operation with their simulation results. For the present work, we have used EDFA design software tool. It simulates various characteristics such as amplified spontaneous emission, gain, noise figure etc. in efficient manner. The working principle of this software provides accurate simulations and results. It confirms the excellent agreement between simulations and results obtained in real EDFA design. The proposed model consists of an input source, isolator, pump source, erbium fiber and WDM coupler. By changing the design parameters such as Input signal power and Pump Power, the different performance parameters (gain and noise figure) can be optimized. Without changing the values of isolator, erbium fiber length and WDM coupler and keeping the values of Input signal power -30dBm and Pump Power 80mW the obtained optimized gain is 34.45dB for single wavelength source and 32.924 dB for multi wavelength source.

“…By using high pump powers or by changing erbium doped fiber length or by varying input power one can achieve flat gains [9][10][11][12]. One can also achieve it by properly choosing optical notch filter characteristics [13].…”

The gain flattening of erbium doped fiber amplifier (EDFA) is essential for their application in wavelength division multiplexing (WDM) system. This paper attempts to design and analyse a 32 channels WDM system using EDFA in the wavelength range of 1546 to 1560 nm with channel spacing of 0.4 nm. The analysis is made for the data rate of 10 Gb/s of NRZ signal. The gain flattening of EDFA in such system is achieved through EDFA's pump power and input power variation. Results show that the gains are flattened within 43.6 ± 0.8 dB with noise figure about 7.38 dB at pump power of 600 mW and input power of -34 dBm using optimized erbium doped fiber of 6.2 m length. The performance analysis in terms of BER, eye diagram and Q factor shows satisfactory results.
