Working Principle of Optical Cable Spiral Vibration Damper
Spiral vibration dampers are specialized devices designed to mitigate oscillations in cables caused by environmental factors such as wind and ice loading. They work by absorbing kinetic energy from vibrations, thereby reducing stress on overhead line hardware and prolonging its. It functions on transmission line infrastructure to protect conductors and cables from damage. Among the leading solutions available in this domain is Spark Fittings' range of products, including their Opgw Cable Preformed Vibration Damper and Electric Power Accessories Galvanize Spiral Cable Vibration Damper.

Characteristics of Optical Cable Vibration Detection
In this paper, various technologies of distributed fiber-optic vibration sensing are reviewed, from interferometric sensing technology, such as Sagnac, Mach–Zehnder, and Michelson, to backscattering-based sensing technology, such as phase-sensitive optical time domain. Optical parameters such as light intensity, phase, polarization state, or light frequency will change when external vibration is applied on the sensing fiber. This study proposed a dynamic model of the interaction between the optical cable and the soil, analyzed the impact of the dynamic parameters of the optical cable and soil on the sensitivity of the DAS system, and validated the theoretical analysis through experiments. 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.
