[0002] A communication optical cable is laid around the buried pipeline, with one core used as a sensing fiber and the other as a communication fiber. Fiber optic repeater amplification devices are added along the sensing fiber, and the communication fiber connects to the detection device and the data and control module. The data and control module transmits the repeater control signal from the repeater amplification device through the communication fiber, enabling real-time adjustment of the repeater amplification. The repeater amplification device can simultaneously amplify the forward-transmitting pulse light wave and the backward-transmitting Rayleigh interference signal. By dividing the detected forward and backward curves, background noise is filtered out, improving positioning accuracy.

Example 2:

[0023] Based on Example 1, please refer to Figure 6-7 Furthermore, in conjunction with Embodiment 1, the auxiliary limiting mechanism 5 includes a limiting platform 51, which is fixedly connected to the right side of the rotating plate 422.
