BER evaluation of multichannel optical fiber transmission system with PSK modulation

Abstract

“The rapid growth of data traffic, fueled by internet services, streaming media, and cloud computing, necessitates highly efficient and dependable communication networks.Optical Fiber Communication (OFC) systems are critical due to their high bandwidth and low attenuation, with Phase Shift Keying (PSK) being the preferred modulation technique due to its spectral efficiency and noise immunity. However, signal distortion phase noise, nonlinear effects, and interference degrade PSK performance. Erbium- Doped Fiber Amplifiers (EDFA) and Semiconductor Optical Amplifiers (SOA) are used to achieve amplification, which is required to maintain signal strength across long,, distances. While EDFAs provide high gain and low noise, and SOAs provide compactness and fast gain dynamics, integrating these amplifiers with PSK introduces additional complexities, such as noise accumulation, nonlinear interactions, gain saturation, There are also wavelength-dependent gain variations. This study looks into the integration of PSK, EDFA, and SOA in OFC systems, with the goal of improvingperformance by characterizing amplifier impact, mitigating signal distortion and nonlinear effects, optimizing amplifier configurations, and improving system robustness and efficiency using advanced signal processing, hybrid modulation schemes, and error correction methods. The findings are intended to significantly advance high-performance OFC systems capable of meeting the growing demands of modern telecommunication networks...”
