This paper proposes bit repetition coding as a simple and effective method to enhance signal fidelity at the receiver. Our approach achieves a significant reduction in the bit error rate (BER), with simulations showing a decrease from 10–3 to 10–10 as the repetition count increases from 3 to 7. Furthermore, the clarity of the received signal improves consistently, with errors approaching zero at optimal repetition levels. This balance between simplicity and performance demonstrates the potential of repetition coding as a robust solution to transmission noise. Beyond its practical benefits, the study opens new pathways for designing resilient optical communication systems and highlights the relevance of repetition coding in improving both system reliability and efficiency. Future research is encouraged to explore its integration into next-generation optical networks.}, type={artykuł}, title={Enhancing optical fiber communication systems using repetition coding for improved signal fidelity and error reduction}, keywords={optyka, optical communication systems, repetition coding, bit error rate, quality factor Q, error correction techniques, optical fiber transmission}, }
