Original Abstract

This work deals with the measurements with distributed acoustic sensing (DAS) systems using standard telecommunication optical fibers. In this work is also discussed the polarization fading suppresion using polarization diversity. As part of this work, measurements were made with an experimental DAS system. This DAS system used dual polarization 90-degree hybrid for polarization fading supression. During these measurements sinusoidal disturbance around the fiber was simulated. The method of data processing and the evaluation of the measured data are presented in the last part of this work.
