方案应用图例一

产品支持多种光纤网络拓扑结构:点对点通讯、链型网络、星型网络及冗余环网自愈保护等拓扑结构,

并可在此基础上组网为更复杂的网络拓扑结构

点对点(Point to Point) 应用场合:某些单独分散的总线节点间需要远距离通讯,或者受干扰严重需要电气隔离:

链型(Line) 应用场合:多个总线节点间需要远距离通讯,或者多个节点间需要完全的电气隔离抗干扰:

应用方案图例二

星型(Star)应用场合:多个节点之间需要改变总线链型拓扑方式,或者多个节点间需要完全的电气隔离时;

应用方案图例三

环形(Circle):应用场合:多个节点间需要提供冗余光纤链路保障总线可靠通讯时

应用方案图例四

本系列产品应用灵活,同时,该系列产品可采用双光口实现双纤环网冗余功能,当某处光纤故障时,系统会在10ms内重建网络链路,保障系统的正常通信,实现对总线信号传输的自愈保护功能,网络故障排除后系统会自动恢复。
