The temperature dependency of the saturated signal power for the transition in erbium-doped fiber amplifiers (EDFAs) pumped at 980 nm and 1480 nm pump wavelengths within a temperature range from 20 to 60 oC are investigated by a novel approach. For 1480 nm pumping regime, it is seen that the saturated signal power increases more quickly than that of 980 nm pumping regime, with the increasing temperature. The variation in the saturated signal power with temperature is nearly constant at 980 nm pumping regime. In addition, the population inversion with respect to the increasing normalized signal power is examined and it is seen that it is independent of temperature for 980 nm but it strongly depends on temperature for 1480 nm especially at lower normalized signal powers.
