摘要： A method for locating a fault of a submarine cable, a device, and a communication system are provided. A light pulse output by a Repeater , RPT, is incident to a location of a fault as a probe light pulse. The RPT obtains a time difference between the probe light pulse and the reflected probe light pulse, and sends the time difference to a terrestrial Submarine Line Terminal Equipment , SLTE, so that the SLTE may easily locate the fault according to principles of an Optical Time Domain Reflector ,OTDR. Compared with the prior art, the method may locate the fault of the submarine cable more quickly and accurately, so that maintainers may maintain the submarine cable in time.
摘要翻译：提供了一种用于定位海底电缆，设备和通信系统的故障的方法。由Repeater RPT输出的光脉冲作为探测光脉冲入射到故障位置。 RPT获得探测光脉冲和反射探测光脉冲之间的时差，并将时差发送到陆地海底线路终端设备SLTE，以便SLTE可以根据光时域原理轻松定位故障反射器，OTDR。与现有技术相比，该方法可以更准确地定位海底电缆的故障，从而维护者可以及时维护海底电缆。
