Dynamic measurements of optical phase modulation in a single-mode fiber subjected to controlled mechanical vibrations are reported. An accurate analysis of the fiber strain state explains the observed phase vs frequency characteristic behavior. The integration properties of the single-mode fiber are evaluated quantitatively for the vibrations applied. The experimental results emphasize the excellent capabilities of optical fibers to sense mechanical vibrations.
