An EDFA theoretical analysis considering different configurations and pumping wavelengths

The propagation behavior of an erbium-doped fiber amplifier parameters is theoretically analyzed in this work for different amplifier configurations and pumping wavelengths. These configurations were devised from the basic amplifier arrangement and developed to improve specific amplifier operational characteristics. By using the amplifier basic theory for pumping at 980 nm and 1480 nm, the configurations were modeled and simulated for given input boundary conditions. As a result, the longitudinal characteristics of signal, pumping, spontaneous emission, and noise figure were observed for all configurations and compared to those of the conventional amplifier. All simulations were carried out using parameters from a commercial erbium-doped fiber.
