摘　　要：由于病毒和黑客日益猖獗,泄密事件逐渐增多,设计了一款基于单纤单向多模光纤的网络信息安全单向传输系统。在硬件设计中,单向传输系统采用光发送器和光接收器实现了基于单纤单向多模光纤的单向传输卡。在软件设计中,提出了"推"和"拉"两种数据传输方式,实现了无反馈的稳定传输技术。该单向传输系统既能实现从低密级网络获取信息又能防止高密级网络信息泄露,提高了网络之间信息交换的安全性。Due to viruses and hackers are becoming increasingly rampant leaks gradually increased, the paper designed a network information security and one-way transmission system which based on single-fiber one-way multi-mode fiber. In hardware design, one-way transmission system based on single-fiber one-way multi-mode fiber and using optical transmitter and optical receiver to achieve one-way transfer card. In software design, proposed a ＂push＂ and ＂pull＂ two kinds of data transmission to achieve the stability of no feedback-free transmission technology. The one-way transmission system that is possible to obtain information from low-Security Level Network can prevent high Security Level network information disclosure, improve the exchange of information between the network securities.
