OTN技术在三峡通信传输网络中的应用

Application of Optical Transmission Net Technology in Communication Network in Three Gorges Project

利用OTN技术,解决了三峡对外互通信息包括电力线路保护系统、电力线路安全控制系统、电力调度系统、电力自动化系统等电力信息传输通道,以及三峡集团对外各类管理信息、数据信息等通信通道需要。OTN技术就是将1根光纤分解成"多车道"多层通行的信息公路,为三峡的通信发展提供了足够的基础信息传输通道保障。

The OTN （ Optical Transmission Net ） technology adopted in Three Gorges project is described , which can fulfill the requirement of outward information exchange , including the power information transmission channels for power line protection system , power line security control system , power dispatching system , and electric power automation sys-tem, as well as the outward communication channels for management information and data .The OTN technology is able to split an optical fiber into a “multi-lane” multi-layer traffic information highway , thus provides a solid ground for the development of communication systems in Three Gorges project .
