Abstract

In this paper, analytical and simulation models were used to analyze the performance of the erbium-doped fiber amplifier in terms of its pump power, erbium-doped fiber length, overlap factor, erbium ions concentration, and input signal power. The analytical-based analysis was performed using MATLAB software, whereas the simulation-based analysis was performed using Optisystem software. Both the analytical- and simulation-based results agreed well. For example, both confirmed the followings: Maximum gain can be reached at a shorter fiber length as the overlap factor and erbium ions concentration increase; the gain is independent of the pump power at values of erbium-doped fiber lengths ≤10m; that almost equal erbium-doped fiber gains can be obtained as the pump power approaches its highest value and that the gain seems to be equal at low values of input signal powers; however, it starts to saturate as the input signal power increases.
