Abstract

The contemporary telecommunications system heavily depends on extensively spread optical fiber networks, which form its fundamental basis. Mechanical forces stemming from diverse ambient vibrations, including human activities and seismic movements, induce strains in these fibers. As a consequence, the light passing through the fibers experiences phase shifts. Consequently, these phase shifts can be detected throughout the entire fiber, offering insights into the original vibration occurrences. This characteristic renders them exceptionally suitable for distributed seismic sensing.
