Özet

The main goal of designing a multi-stage fiber amplifier is to achieve higher performance for long-haul optical transmission systems. In this paper, multi-stage triple-pass (TP) TDFAs are represented. Three types of TP-TDFA are modeled, optimized, and compared. Firstly, signal power, pump power, fiber length, and ion concentration were optimized in the input signal at the 1469 nm wavelength, which gives the highest gain in the S-band. Secondly, the input signals in the 1444-1499 nm band gap were amplified using these optimized values in all designs. Finally, all types were compared to conclude the best TP-TDFA.
