Abstract
As the core technology of modern information transmission, high-speed fiber communication system is faced with the signal distortion caused by dispersion effect. To solve this challenge, this paper studies the dispersion compensation technology in high-speed optical fiber communication, aiming to improve the transmission performance and stability of the system. Based on the rapid growth background of high-speed data transmission demand, a hybrid dispersion compensation scheme combining digital signal processing and optical fiber device optimization is proposed. By introducing an advanced adaptive algorithm and a high-precision fiber Bragg grating design, this method is able to dynamically adjust the dispersion compensation amount to accommodate different transmission conditions. The experimental results show that the proposed scheme significantly reduces the closure of signal and effectively improves the performance of bit error rate at 100 Gbps or above. Compared with the traditional single compensation means, this technique exhibits better stability and robustness in long-distance transmission.
