Three-stage six-pass EDFA preamplifier design and EDFA parameters’ optimization

Optical and Quantum Electronics, 2021
In this study, three-stage six-pass erbium doped fiber amplifier (EDFA) is performed. The mathematical model to characterize this proposed EDFA are also developed. During the design process, EDFA's input signal wavelengths, EDF lengths and pump powers are optimized.
