Comparative Analysis of EGGN vs. GGN Models for Hybrid Raman/DFA Amplified Ultra-Wideband Optical Networks

Paper in proceeding, 2025

This paper presents a comparative analysis of the Enhanced Gaussian Noise (EGGN) and Gaussian Noise (GGN) models for estimating nonlinear interference (NLI) in hybrid Raman/doped fiber amplifier (DFA)-based ultra-wideband optical networks. Results demonstrate that the EGGN model achieves a significant 2.6 dB improvement in GSNR compared to the GGN model. Furthermore, the study utilizes an analytical solution to compute the NLI, reducing computation time from 7.5 hours to 2 minutes. These findings highlight the benefits of the EGGN model and the efficiency of the analytical approach for accurate and rapid performance assessment of ultra-wideband optical systems.
