摘要
简要概述了水下信息网系统的组成结构,然后基于Optisystem建立了400km长距离水下信息网的仿真模型,主要对水下链路上的EDFA光放大的跨段进行研究。对比分析了其不同的节点分支单元增加光放大器时信号的传输情况,研究结果表明在水下信息网分支单元合理安排光放大器,可获得较满意的传输性能。
The structure of the underwater information network is briefly summarized.Based on the Optisystem,a simulation model of 400 km long-distance underwater information network is established.The amplification span of EDFA on the underwater links is mainly researched.It＇s signal transmission performance is comparatively analyzed when optical amplifiers are added to the branch units of different nodes.The result indicates that the reasonable arrangement of optical amplifiers in the branch units of the underwater information network can get relatively good transmission performance in the network.
