典型应用
Typical applications
地热井下，石油井下，CCUS，储气库，空气储能等环境对设备的绝对温度精度更高要求的场景
Downhole geothermal wells, downhole oil wells, CCUS projects, gas storage facilities, compressed air energy storage systems, and other applications with higher requirements for absolute temperature accuracy.
空间分辨率、采样间隔与定位精度为不同指标。温度精度随光纤长度、采集时间、温区及光缆配置变化；各项最优指标不代表在同一配置下同时达到。
Spatial resolution, sampling interval and location accuracy are distinct quantities. Temperature accuracy depends on fiber length, acquisition time, temperature range and cable configuration; optimum values are not necessarily simultaneous.
空间分辨率按10%–90%阶跃响应口径列示，采用“±”空间范围记法；定位精度另列。规格比较须采用相同定义与测试条件。
Spatial resolution uses the 10%–90% step-response criterion and the ± spatial-extent notation used in this datasheet. Location accuracy is specified separately. Compare specifications using the same definitions and test conditions.
