Abstract: The positioning of Erbium-Doped Fiber Amplifiers (EDFAs) plays a crucial role in optimizing the performance of Dense Wavelength Division Multiplexing (DWDM) systems, particularly in addressing signal attenuation challenges in long-distance optical transmission. This study investigates the impact of EDFA placement configurations (booster, in-line, and pre-amplifier) on signal quality using OptiSystem software simulations. The research examines systems with 4 to 16 DWDM channels, operating at 10 Gbit/s per channel with 50 GHz spacing, varying total input power between -10 dBm to 5 dBm. Results demonstrate that the booster amplifier configuration performs best, while the pre-amplifier setup exhibits more pronounced degradation. The in-line amplifier configuration shows a balanced performance, effectively restoring signal strength while requiring less pump power than the booster configuration, making it a viable option for optimizing energy efficiency in DWDM systems. A critical performance threshold was identified between 10-12 channels, where all configurations experience significant changes in error performance.
