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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
