The peculiarity of the method is the use of pulsed impact for approximate determination of the cable laying area and the use of an acoustic source to determine the direction and clarify the location of the tracing route. The study outlines tracing algorithm and recommendations for choosing acoustic impact parameters. In accordance with the method elaborated, field tests were carried out on the section of a fiber-optic communication line made using a fully-dielectric optical cable. In result of the experimental testing, the possibility to determine a cable route tracing location under conditions of electromagnetic and acoustic interference with an error of not more ±0.2 m was demonstrated.</p></abstract><trans-abstract xml:lang="ru"><p>В статье представлен метод поиска трассы для прокладки подземных диэлектрических оптических кабелей, основанный на регистрации и анализе откликов фазочувствительного оптического рефлектометра на вибро-акустические воздействия в предполагаемой области прокладки. Особенность метода заключается в использовании импульсного ударного воздействия для примерного определения зоны прокладки кабеля и применения источника акустического воздействия для определения направления и уточнения местоположения трассы прокладки. В работе изложен алгоритм выполнения трассопоисковых работ и рекомендации по выбору параметров акустического воздействия. В соответствии с разработанным методом были проведены полевые испытания на участке волоконно-оптической линии связи, реализованном с использованием оптического кабеля полностью диэлектрической конструкции. В результате экспериментальной апробации была продемонстрирована возможность определения местоположения трассы кабеля в условиях электромагнитных и акустических помех с погрешностью не более ±0,2 м.</p></trans-abstract><kwd-group xml:lang="en"><kwd>cable route tracing</kwd><kwd>fully dielectric optical cable</kwd><kwd>acoustic signal</kwd><kwd>phase-sensitive optical time-domain reflectometer</kwd><kwd>distributed acoustic sensing</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>поиск трассы прокладки</kwd><kwd>диэлектрический оптический кабель</kwd><kwd>акустический сигнал</kwd><kwd>фазочувствительный оптический рефлектометр</kwd><kwd>система вибро-акустического мониторинга</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><citation-alternatives><mixed-citation xml:lang="en">Andreev V.А. et al.
