Abstract
We present in this work the dependence of the macro-bending EDFAs Gain and noise figure on the temperature, where the dependence of both gain and noise of macro-bending EDFA and without macro-bending are calculated for the temperature range (-40 to 600C) with bending radius 4 mm for the case of amplifier with bending single mode EDFA pumped at 980 nm. We obtained improvements for the gain and noise figure of macro-bending EDFA due to bending loss as well as temperature changes. where the gain increase to ~ (2- 6 dB) for the amplifier length (5-15m) at temperatures +20, -20 and 60 0C and the maximum value of the gain was ~ 16 dB at amplifier length 20 m at this range of temperatures. furthermore the noise figure is reduced by ~ 5 dB with macro-bending for amplifier length L= 25 m and by ~ 34 dB at 30 m of amplifier length at the temperatures -40, +20 and +60 0C. Finally, the gain is higher by ~ 5 dB when the temperature increases from -40 to 60 C with macro-bending at a wavelength 1540 nm, and the noise figure reduces at the wavelength 1540 nm by ~ 0.44 dB for temperature changes from -40 to 60 0C for macro- bending EDFA..
