Abstract: In this study, we investigate the influence of Distributed Feedback (DFB) lasers on the performance of Erbium-Doped Fiber Amplifiers (EDFA) and explore the EDFA system using coupled mode equations. Our primary objective is to minimize amplified spontaneous emission (ASE) while maintaining a high gain (G). Key factors affecting gain, such as pump power (Pp), erbium doping radius (Rd), EDFA length (LEDFA), and input signal power (Ps), are analyzed analytically. We examine the propagation behaviour of ASE, gain trends, population inversion, pump signal, and input signal. To mitigate ASE, Fiber Bragg Grating (FBG) is employed. The DP-FBG EDFA configuration demonstrated a gain improvement of 3 dB and a reduction in ASE power by approximately 4 dBm compared to the SP-EDFA configuration. Further comparisons were made across different wavelengths in the C-band, revealing that the optimized EDFA-FBG configuration outperforms the initial setup. Further, out of all the four lasers in C-band, 1550 nm DFB laser maintains Q-6 for longer fiber length with an EDFA having Lopt of 10.52 m, Rd-opt of 2.2 µm and Psat of − 22.43 dBm. Additionally, the quality factor was assessed, showing that the optimized configuration maintains a higher quality factor. Notably, using FBG as a filter allowed the maintenance of Q-6 over 100 km, whereas an inverted Gaussian filter sustained Q-6 only over 40 km. [ABSTRACT FROM AUTHOR]
