摘要
在多用户信息传播过程中,光纤通信系统存在数据碰撞和冲突现象,为了改善光纤通信系统的性能,提出一种基于光码分多址编解码技术的光纤通信系统安全分析方法。首先对光纤通信系统的研究现状进行分析,找到数据碰撞和冲突产生的原因,然后采用动态时隙法解决数据碰撞和冲突难题,避免数据传输丢失,最后并通过具体实验测试了本文方法的性能。测试结果表明,本文方法可以有效抑制数据的碰撞和冲突,增强光纤通信系统的安全性,可以实现有效的光纤通信。
In the process of multi-user information transmission,there is a data collision between the fiber communication system,a fiber communication system security analysis method is proposed in order to improve the security performance of optical fiber communication system based on optical code division multiple access coding and decoding technology.Firstly,research status of optical fiber communication system is analysed to find the causes of data collision between users,and a light threshold is used to solve multi-user data collision and avoid the losing of data trarismission,at last,specific experiments is used to test the performance of the method in this paper.Test results show that,the proposed method can effectively suppress the crosstalk between users,enhance the security of optical fiber communication system,so it can realize offective optical fiber communication.
