The possibility of full-fledged Brillouin monitoring of fibers connected to the splitter spurs of a passive optical network under condition of application of the end reflection method is presented. Resolution capability of reflectometers of this variety is evaluated.</p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрены физические основы методов измерения деформации оптического волокна на основе анализа во временной области рассеяния Мандельштама − Бриллюэна. Показана возможность проведения полноценного бриллюэновского мониторинга волокон, подключенных к отводам сплиттера пассивной оптической сети при условии применения метода концевых отражений. Даны оценки разрешающей способности рефлектометров данной разновидности.</p></trans-abstract><kwd-group xml:lang="en"><kwd>PON</kwd><kwd>PoLAN</kwd><kwd>optical fiber strain measurement</kwd><kwd>Brillouin optical reflectometry</kwd><kwd>Brillouin OTDR</kwd><kwd>Brillouin frequency shift</kwd><kwd>Brillouin end-reflection analysis</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>PON</kwd><kwd>PoLAN</kwd><kwd>измерение деформации оптического волокна</kwd><kwd>бриллюэновская оптическая рефлектометрия</kwd><kwd>бриллюэновский рефлектометр</kwd><kwd>бриллюэновский сдвиг частоты</kwd><kwd>бриллюэновский анализ на концевых отражениях</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Шевелев С., Семенов А.
