This paper makes the analysis of fiber optic cable tracking and positioning analysis based on distributed fiber vibration sensing.
Based on this, a distributed optical fiber vibration sensing and positioning scheme by combining distributed polarization state detection with cross-correlation analysis is further proposed.
The conventional distributed fiber optic positioning system (DFOPS) employing a single pulse working has a mutually constrained relationship between resolution and measurement
1. What is Distributed Fiber Optic Vibration Sensing (DVS)? Distributed Fiber Optic Vibration Sensing (DVS) is an advanced optical sensing technology that uses
To solve the above problems, we propose a method for vibration area localization and event recognition of the underground power optical cable based on PGSD-YOLO and 1DCNN
To validate the effectiveness of the proposed positioning scheme, experiments were conducted to localize vibration events along a 101-km sensing fiber cable using an annular
Therefore, when the differential phase-OTDR is adopted to accurately position the vibration position of the optical cable, the problem of the vibration positioning blind area of the...
