Выполнена математическая аппроксимация экспериментальных кривых роста радиационно-наведенных оптических потерь в волокне при помощи модифицированного уравнения степенной функции, включающего вклад мощности дозы ионизирующего излучения. Экспериментально установлена корреляция значений эмпирических коэффициентов и мощности дозы ионизирующего излучения. Предложено уравнением функции натурального логарифма описывать зависимость эмпирических коэффициентов, задающих форму кривой роста радиационно-наведенных потерь, от мощности дозы. Предложен подход к восстановлению кривой роста радиационно-наведенных потерь по уравнениям зависимости эмпирических коэффициентов аппроксимации от мощности дозы, что позволяет прогнозировать радиационный отклик рассматриваемого оптического волокна в новых условиях без постановки опыта. Подход показал применимость для одномодовых волокон с кварцевой и германосиликатной сердцевинами световода разной конструкции. На основе описанного подхода составлена методика определения корреляционных уравнений для эмпирических коэффициентов.</p></abstract><trans-abstract xml:lang="en"><p>Experimental results of a study of the effect of ionizing radiation with different dose rates on fiber-optic systems using fibers with a germanosilicate core (GeO2) and an undoped pure silica core (SiO2) are presented. A mathematical approximation of the experimental curves for the growth of radiation-induced optical losses in the fiber is performed using a modified power-law equation that includes the contribution of the ionizing radiation dose rate. A correlation between the values of empirical coefficients and the dose rate of ionizing radiation is experimentally established. A natural logarithmic function equation is proposed for describing the dependence of the empirical coefficients defining the shape of the radiation-induced loss growth curve on the dose rate. An approach to reconstructing the radiation-induced loss growth curve using equations for the dependence of the empirical approximation coefficients on the dose rate is proposed; this technique enables predicting the radiation response of the optical fiber under new conditions without experimental setup. The method demonstrates applicability for single-mode fibers with silica and germanosilicate fiber cores of different designs. Based on the described approach, a methodology is developed for determining correlation equations for empirical coefficients.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>радиационная стойкость</kwd><kwd>оптическое волокно</kwd><kwd>радиационно-наведенные оптические потери</kwd><kwd>ионизирующее воздействие</kwd><kwd>математическая аппроксимация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>radiation resistance</kwd><kwd>optical fiber</kwd><kwd>radiation-induced optical losses</kwd><kwd>ionizing effect</kwd><kwd>mathematical approximation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Girard S. et al.
