Performance analysis of hybrid DRA-SOA for WDM based fiber optic transmission system

Abstract

This study investigates the performance of hybrid amplifiers, which combine Distributed Raman Amplification (DRA) and Semiconductor Optical Amplifiers (SOAs), aiming to enhance optical fiber transmission systems. The main goal is to meet the growing demand for increased transmission capacities by improving optical fiber amplifiers. The research focuses on assessing the effectiveness of these hybrid amplifiers under various operational conditions, including pump power, fiber length, and the number of wavelength-division multiplexing (WDM) channels. It aims to shed light on how these amplifiers impact critical system parameters such as dispersion, bit error rate (BER), and signal degradation over long transmission distances. Through comprehensive analyses of gain and BER performance, the study seeks to refine hybrid amplifier configurations and contribute to advancements in optical communication technology. Simulation setups integrating Erbium-doped Fiber Amplifiers (EDFAs) with SOAs, along with simulations and measurements, are utilized to evaluate gain and BER performance. The findings underscore the significant role of DRA-SOA hybrid amplification in improving system efficiency, particularly in terms of signal amplification, noise reduction, and error rate reduction. Overall, this research offers valuable insights into the design, optimization, and practical implementation of DRA- SOA hybrid amplifiers, thereby advancing optical fiber transmission capabilities and enhancing system reliability in communication networks.
