Abstract
Distributed optical fiber sensing technology developed rapidly in the late 1970s with the development of optical fiber sensing technology and optical fiber communication technology. Distributed optical fiber sensing technology is very suitable for the monitoring of long-distance trunk as it can obtain continuous distributed information along the space and time in the physical field. At present, this technology has become one of the most promising technologies in optical fiber sensing technology. 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 sensing optical fiber on the vibration signal; it can also be used in the monitoring of long-distance communication lines. This paper analyzes the fiber optic cable tracking and positioning analysis based on distributed fiber vibration sensing.
