Abstract

A power-feeding system developed for digital signal-transmission systems on optical fibers is presented. It consists of 1 to 3 power-feeding units (400 mA, 700 V each), a power-feeding control unit, the power-feeding cable and the remotely-fed converters to supply the loads. The power-feeding control unit performs a route test before the power-feeding is switched on, locates route faults and monitors the entire power-feeding system during operation. The converters, series-connected in the power-feeding circuit, each have two mutually isolated outputs rated 60 V/25 W. The outputs of one or more converters can be connected in parallel. The reach of the system is determined, apart from the maximum available power-feeding voltage, only by the resistance of the cable used and the power-requirement of the equipment to be fed. Several hundred kilometers can be spanned. The modular structure of the power-feeding system allows to fulfi11 various requirements in regard to system architecture, power, redundancy and economic efforts. As well as fiber-optic systems, other loads in the power range of approximately 10 to 200 W can be supplied.

一种用于数字光波导传输的灵活、模块化供电系统

介绍了一种用于光纤数字信号传输系统的馈电系统。它由1 ~ 3个电源馈送单元(每个400ma, 700v)，一个电源馈送控制单元，电源馈送电缆和远程馈送转换器组成，用于供电负载。上电控制单元在上电前进行线路测试，定位线路故障，监控整个上电系统运行。转换器串联在供电电路中，每个转换器有两个相互隔离的输出，额定功率为60v / 25w。一个或多个转换器的输出可以并联连接。除了可用的最大供电电压外，系统的范围仅由所使用电缆的电阻和要馈电的设备的功率要求来确定。可以跨越数百公里。电源馈电系统的模块化结构可以满足系统架构、功率、冗余和经济方面的各种要求。除了光纤系统外，还可以提供功率范围约为10至200w的其他负载。
