Vibration damper for power fiber optic cables
Vibration Damper for electric power cable is divided into two types, including spiral vibration damper and 4D vibration damper. IEC describes the Stockbridge damper as a system consisting of a messenger cable with two masses at its ends and a clamp that supports them; this clamp is attached to the conductor or earthwire with the purpose of reduction of the aeolian vibration on the conductor. Sure enough, starting from a. The method may consist of placing an inflatable bladder between an optical fiber and a protective jacket. The bladder may be inflated with air, inert gas, or liquid to a desired pressure. Most tuned damping devices operate best near their natural frequencies. Vibration dampers work to cancel damaging fatigue caused by wind-induced vibration. Wind-induced vibration of aerial conductors is common worldwide and can cause conductor fatigue near a hardware attachment.

Advantages of Vibration Sensing Fiber Optics
Among them, FBG vibration sensors have become a fast-developing scientific research field owing to intrinsic advantages such as low noise, good embeddability, and ability to be easily multiplexed to construct a distributed sensor array [23, 24]. 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 reflectometer. Fiber Optic sensors (FOS) provide many advantages over conventional sensors [2, 3], some of them as listed in Table 1. Suitable for harsh environment and remote monitoring systems can be made easily. Potentially easy to install Table 1.
