产品原理与应用 Principle and applications
基于自发布里渊背向散射与光时域定位，采用单芯光纤、单端接入，获取沿线布里渊频移及温度或应变分布。最大配置量程60 km，典型测量时间60–300 s/通道。
Uses spontaneous Brillouin backscattering and time-domain localization. Single-core, single-ended access measures Brillouin frequency shift and temperature or strain along the fiber. Maximum configured range is 60 km; typical acquisition time is 60–300 s/channel.
布里渊频移同时受温度与轴向应变影响。测量应变时需要温度补偿，测量温度时需要消除或约束应变影响；单条频移曲线不能独立分离两个未知量。
Brillouin frequency shift responds to both temperature and axial strain. Strain measurement requires temperature compensation; temperature measurement requires strain isolation or correction. One frequency-shift trace cannot independently determine both unknown quantities.
采用光学传感与传输，抗电磁干扰；支持连续沿线测量、事件定位、光纤故障监测及长期状态管理。危险区域的光缆与整套系统按相应使用条件选配。
Optical sensing and transmission resist EMI and support continuous profiles, event location, fiber-fault monitoring and long-term condition management. Select the cable and complete system for the applicable hazardous-area conditions.
量程、空间分辨率、平均时间与测量精度存在配置关联，长距离与最高分辨率不一定同时达到。温度量程取决于传感光纤及护套；应变需通过可靠机械耦合传递至光纤。
Range, spatial resolution, averaging time and accuracy are configuration-dependent and not necessarily achieved simultaneously. Temperature range depends on the fiber and jacket; strain requires reliable mechanical transfer into the fiber.
