Abstract
Based on the common interference problem in the system of optical fiber communication, this paper is analyzed from the aspects of signal processing and algorithm optimization. Signal processing technology includes equivalence, time domain filtering and frequency domain filtering, which can eliminate or reduce signal interference and improve signal quality and reliability. The algorithm optimization techniques include window adding, pulse pressure and adaptive equilibrium, which can improve the anti-interference ability of the system, while ensuring higher transmission rate and transmission quality, and improve the robustness and stability of the system. Considering the above technical means, the optimal pretreatment effect can be realized, the transmission quality and reliability of the optical fiber communication system can be improved, and the normal operation can be guaranteed.
