一种实现多媒体业务的新型光纤专用网络

A Novel Optical Fiber Netloork with Multimedia Function

本文介绍了基于以太网的新型多媒体光纤工业监控网的设计方法，探讨了其组网原理和实现功能，提出采用以中继式集中器和交换式集中器相结合的双层树型拓扑结构的组网方式，并定量地分析了网络的可用性。结果表明该网络适用于多媒体工业监控系统，可靠性高，成本低，可满足多媒体信号的传输。

A novel optical fiber supervisory control industrial network based on Ethernet is put forward. We analyze its networking principle and realizing function, and present 2 level trees of networks topology by using relay hub and swiching hub, and demonstrate the availability of industrial network by means of quantitative analysis. This high speed broadband network can be used in multimedia industrial control system with high reliability and low cost, and fit for transporting multimedia signals.
