摘要

In order to achieve unidirectional ,safe ,high‐speed and stable data transmisson be‐tween different safety levels ,single mode optical fiber was adopted as transmission media ,loop‐back verification ,forward error correction and majority judgement technologies were combined .In view of the characteristics of optical transmission ,the technological verification was conducted on the unidirectional ,safe and high‐speed transmission based on concurrent multi‐channel optical processing .Experimental results proved the feasibility of the system ,with anticipated outcome ,in unidirectional transmisson and the security and speed of the transmission .%为了实现不同安全级别间数据单向、安全、高速及稳定的传输，通过单模光纤作为传输介质，采用数据环回校验技术、前向纠错技术、多数判决技术，实现了数据的单向安全高速传输。结合光传输的特点，进行了基于并发多路光处理的单向安全高速传输的技术验证。实验结果表明，系统在单向传输及数据传输的安全性和高速性均已达到预期的效果，方法可行。
