The results indicate that for practical applications, the most effective deployment method is the cement-bonded fixed fiber optic cable on the road shoulder, followed by the uncoupled fiber on the road, and the underground communication fiber optic cable ducts are the least.

Distributed fiber-optic vibration sensors receive extensive investigation and play a significant role in the sensor panorama. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. In this paper. The fiber distributed vibration sensor system put forward in this paper is a new kind of distributed optical fiber sensing system, which can realize real-time extraction of arbitrary vibration signal. It is exerted to the sensing optical fiber and can accurately determine the position of the. Distributed Fiber Optic Vibration Sensing (DVS) is an advanced optical sensing technology that uses single-mode optical fiber (SMF, G652 recommended) as both the sensing medium and signal transmission carrier. Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time. Vibration analysis is one of the proven methods in fault detection in a variety of dynamic components. However, lack of experimental data on actual machinery in comparison to test bench devices, has made it difficult for a reliable fault detection and lifetime assess-ment.
