Comparative Gain Analysis of Erbium and Ytterbium Doped Optical Fibre Amplifiers
نویسنده
چکیده
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.
