Abstract
The out power of the erbium doped fiber amplifiers (EDFAs) irradiated by neutrons with a dose of 1000krad, it is investigated by theoretical and artificial neural network (ANN) modeling. Levenberg–Marquardt algorithm has been used for the ANN modeling. The theoretical as well as ANN models are in good agreement with the experimental data. A minimum acceptable error of 1.4×10−4 has been obtained. The theoretical and the ANN models help us to understand the output of EDFAs in detail. The EDF could be used only in the low radiation dose less than 20krad. The ANN model provide a powerful tool to study the output power of EDFAs.
