摘　　要：噪声对光纤通信系统的性能易产生干扰,影响光纤通信系统的通信质量,为了克服当前光纤通信系统存在的一些不足,以改善光纤通信系统的抗噪声干扰和鲁棒性,设计了一种抗噪声干扰的鲁棒性光纤通信系统。首先分析光纤通信系统的研究进展,设计了光纤通信系统的整体结构,然后分别对当前光纤通信系统的硬件和软件进行改进,通过滤波技术消除噪声的干扰,最后进行了光纤通信系统性能的测试,测试结果表明,在无噪的环境下,光纤通信系统的数据传输成功率均高于96.5%,而在有噪的环境下,光纤通信系统的数据传输成功率均高于94%,很好地抑制了噪声对通信结果的干扰,同时,光纤通信系统的数据传输时延控制在5 s以内,光纤通信系统平均吞吐量大,整体性能明显优于传统光纤通信系统,可以保证光纤通信系统稳定、正常运行。Noise easily interferes with the performance of optical fiber communication systems, and can affect the communication quality of those systems. In order to overcome some shortcomings of current optical fiber communication systems and improve the anti-noise interference and robustness of optical fiber communication systems, a robust defense against noise interference is designed. First, the research progress of the optical fiber communication system is analyzed, and the overall structure of the system is designed. Then the hardware and software of the current systems are improved respectively, and the noise interference eliminated by filtering technology. Finally, the performance of the system is tested. The test results show that in a noise-free environment, the data transmission success rate is higher than 96%, while in a noisy environment, the data transmission success rate is higher than 94%, which well suppresses the interference of noise on communication results. At the same time, the data transmission time of the optical fiber communication system is controlled within 5 s, and the average throughput of the system is large. The overall performance of the system is obviously better than the traditional optical fiber communication system, which can ensure stable and normal operation.
