我们开发了一种全介质光缆用的光缆检测系统。这种系统工作于一根单模光纤上，它监视光缆结构的变化或损坏所产生的微弯与宏弯光损耗，并提供早期的告警。这系统应用一种特殊的潮气检测带和数字编码的电子传感器耦合到监视光纤，独一无二地识别和监视各只接头盒。第一个这种系统用于加拿大Ｍａｎｉｔｏｂａ的一条省内光缆路由上。 We have developed a fiber optic cable inspection system for all dielectric cables. This system operates on a single-mode fiber that monitors the microbend and macrobend loss caused by changes in or damage to the fiber optic cable and provides early warning. The system uses a special moisture detection zone and digitally encoded electronic sensor coupled to the monitoring fiber to uniquely identify and monitor each connector box. The first of these systems was used for a provincial fiber optic cable route in Manitoba, Canada.
