Product Info
Introduction
The PZT fiber vibrator is a fiber optic vibration simulator that induces periodic vibrations in the optical fiber by applying voltage to the PZT material, causing it to undergo cyclic compression and tension.
Overview
The PZT fiber optic vibrator is a fiber optic vibration simulator that applies voltage to piezoelectric zirconate titanate (PZT) material. This causes the material to undergo periodic compression and tension, thereby inducing corresponding periodic vibrations in the fiber optic cable.
Applications
Distributed Fiber Optic Vibration (DVS/DAS) Testing
