Advancements in Long-Distance PON Connectivity using WDM and EDFA

Nowadays a WDM (Wavelength Division Multiplexing) technique becomes more popular in designing PON (Passive Optical Network). EDFA (Erbium-Doped Fiber Amplifier) device used to transmit the signal long distance emerged in the field of optical fiber communication. The primary reason for their development is the increased demand for internet-based applications. This research aims to delve into the advantages, underlying theories, and combined usage of WDM and EDFA in Passive Optical Network (PON) systems. Additionally, this study introduces a hybrid RamanEDFA system and explores the technical aspects of EDFA, including gain calculations and noise analysis. Furthermore, it compares the performance of Semiconductor Optical Amplifiers (SOA) with that of EDFA. By utilizing the Optisystem software, the investigation puts into action WDM PON systems, both with and without EDFA amplification, in order to showcase their practical application. The results indicate that WDM-PONs with EDFA offer the most favorable Q-factor and BER for extensive-range communication, surpassing alternative approaches.
