The features of the amplitude modulation of guided radiation in single-mode fiber lightguides with a low normalized frequency when acted upon by seismic signals are investigated. It is shown that the sensitivity of sections of such lightguides to seismic shocks can reach 6·10–4 g. This makes it possible to use them to construct fiber-optical measuring transducers, whose metrological characteristics enable them to be used to solve a wide range of geophysics problems.
