Аннотация:This research is focused on γ-radiation, the main negative factor which causes significant losses in fiber-optical communication lines. We determine the methods for increasing the relaxation rate of color centers that are formed in an optical fiber under the influence of γ - radiation. Moreover, we develop the design of the fiber-optic communication line with the compensation of radiation-induced losses at the moment of exposure to the optical fiber γ - radiation. The results of experimental investigations are presented.
