Abstract

The article discusses the use of Distributed Acoustic Sensing technology in locating underground all-dielectric optic cables. DAS uses fiber optic cables to detect acoustic vibrations along the cable's length caused by digging or drilling, allowing for precise identification of the cable's location and path without excavation or other intrusive search methods. DAS provides high-resolution data over long distances, making it more accurate than traditional search methods like geo-radar or GPS markers. The article proposes a localization algorithm for detecting the path of all-dielectric optical cables using DAS technology, based on a combination of approximate and point estimates of cable location. The algorithm is tested on a testing ground of a section of an optical communication line, demonstrating the ability to determine the area of optical cable laying with a radius of up to 5 meters in real-time.
