<p>Optical solitons are known for their ability to travel distances without any loss or dispersion. This research presents an innovative solution, for achieving high-capacity optical transmission by combining the advantages of solitons and WDM to transmit 80 channels from each band, totaling 160 channels across the C- and L-band over a single fiber. To minimize channel interference, this study employs orthogonal polarization on alternating channels. The novelty of this research lies in the integration of solitons and WDM through the implementation of polarization strategies, supplemented by detailed graphs on received optical power. It addresses existing challenges and lays essential groundwork for future advancements in ultrahigh-speed optical communications. The objective of this paper is to enhance optical communication systems and create opportunities for effective technologies by pinpointing areas for improvement and suggesting directions for future research. The study includes graphs demonstrating the power required to maintain a reliable signal quality. The results confirm the effectiveness of polarization rotation and parallel amplification, demonstrating improved system performance over extended distances. At 10 Gbps, a BER of 2.22 × 10⁻⁴ was achieved over 1200 km with polarization rotation, compared to 1000 km without it. At 20 Gbps, BER improved to 3.02 × 10⁻³ over 1000 km with rotation, whereas it degraded to 5.96 × 10⁻³ without it. Without polarization rotation, performance declined rapidly, emphasizing its role in maintaining signal integrity. These advancements support reliable long-distance data transmission, contributing to the evolution of digital communication technologies. The study recommends further research to enhance system efficiency and resilience in next-generation optical networks.</p>
