摘要

To compensate for the optical loss, bi-directional (Erbium-Doped Fiber Amplifier) EDFAs are commonly adopted. However, the accurate characterization of output noise and spectral gain in multi-channel long-haul systems is crucial, and conventional methods are expensive and more time-consuming. Hence, we propose a Design Parameter Optimization (DPO) algorithm that optimizes various design parameters for a bi-directional dual-pump EDFA–SOA hybrid system in multi-channel long-haul optical communication. The system operates at 40 Gbps with 8 channels and 5 nm spacing, improving the output response in terms of gain and noise. The algorithm iteratively optimizes key parameters, such as doping length and pump power, to minimize the error between expected and observed outputs. The implemented structure produces the dual-pumping gain ripples of 6.032 dB on average. It investigates various design parameters, compares the obtained output with the expected output, and achieves a 15 Q-factor, 18.5 dB ER, and 28 dB OSNR. The EDFA doping length and pump power are also optimized per the OSNR and Q-factor. The proposed approach improves gain flatness, reduces noise, and enhances transmission performance as compared to existing methods. The results demonstrate the effectiveness of the proposed optimization strategy for next-generation high-capacity optical networks.
