光纤保护接口技术

在全线速动线路主保护配置中纵联光纤保护逐渐占据主导地位,主要讨论了构成纵联光纤保护两端或多端间相互交换保护信息所需接口设备的相关技术,如保护专用光端机技术、复用数字通道技术和同步采样技术等。光纤保护系统的组成主要包括光通信接口设备、光通信系统和光纤保护装置。主要对不同光纤差动保护同步技术和不同光纤保护同步传输技术作了详细比较,认为采样时刻调整法、采样数据修正法是较实用的差动保护同步技术,专用光纤接口、专用SDH系统E1通道接口是应优先采用的光纤保护同步传输技术。

Technology of the interface on fiber optic protection

The pilot fiber optic protection has being dominant in the high-speed through line protection. The paper mainly discusses the technologies of the interface by which the two or three fiber optic protection terminals exchange the relay information, such as optic fiber transmitter/receiver, duplicating digital communication channels , synchronization sampling. The fiber optic protection system includes interface on fiber optic communication, fiber optic system and fiber optic protection. The paper compares fiber optic protection synchronization technologies and fiber optic protection synchronization communication technologies.It concludes that sampling time adjusting , sampling data correcting are scientific techniques, and private optic fiber interface, private SDH E1 interface are firstly used transmission techniques.
