    "abstract": "An analytically expression for the temperature dependence of the signal gain\nof an erbium-doped fiber amplifier (EDFA) pumped at 1480 \\textit{nm} are\ntheoretically obtained by solving the propagation equations with the amplified\nspontaneous emission (ASE). It is seen that the temperature dependence of the\ngain strongly depends on the distribution of population of Er$^{3+}$-ions in\nthe second level. In addition, the output pump power and the intrinsic\nsaturation power of the signal beam are obtained as a function of the\ntemperature. Numerical calculations are carried out for the temperature range\nfrom $-$ 20 to $+$ 60 \\textit {$^{o}$C} and the various fiber lengths. But the\nother gain parameters, such as the pump and signal wavelengths and their\npowers, are taken as constants. It is shown that the gain decreases with\nincreasing temperature within the range of $L\\leq 27 m$.",
