摘　　要：针对核电站场外应急通信数据传输的需求,开展了光纤长距离无中继传输技术的应用研究。首先,介绍了光纤长距离无中继传输的受限因素和安全因素,分别指出其解决措施;然后,提出一种未采用远程光泵放大器(ROPA)的光纤长距离无中继输方法,并进行了实验验证。实验结果表明:光纤链路无中继传输距离达252.15 km,满足核电站应急通信指挥专网的超长距离数据传输和安全的需求。In order to meet the demand of emergency communication data transmission outside nuclear power plant,the application research of long-distance non relay transmission technology of optical fiber is carried out.Firstly,the paper introduces the limited factors and safety factors of long-distance relay free transmission of optical fiber,and points out the solutions respectively.Then,a long distance relay free optical transmission method without remote optical pump amplifier(ROPA)is proposed and verified by experiments.The experimental results show that the non relay transmission distance of optical fiber link is 252.15 km,which can meet the requirements of ultra long distance data transmission and safety of emergency communication command network of nuclear power plant.
