Justification of the scientific research task for estimation of the influence of the factors of ionizing radiation on the efficiency of application of atmospheric-optical communication lines

Abstract

The structure, role and place of atmospheric-optical communication lines in modern information transmission systems and increasing the efficiency of their functioning are considered. The factors are analyzed, and especially such an environmental factor is taken into account, which directly affects the technical characteristics of the element base of atmospheric-optical communication lines, such as radioactive radiation. The source of such radiation can be a nuclear power plant accident, as a result of which a large amount of radioactive substances spreads into the surrounding space outside the nuclear power plant. The analysis of the radiation resistance of the element base of atmospheric-optical communication lines is carried out, which shows that the most vulnerable structural elements are infrared receivers. The technical condition of the receivers of atmospheric-optical communication lines under the influence of radioactive radiation will determine the general technical condition of the information system and affect the possibilities for their application. Radioactive radiation, which is also present in the space environment, is one of the factors in the manifestation of external influences and on the technical condition of aerospace technology. The radiation that occurs in the structures of integrated circuits when bombarded with high-energy particles leads to the generation of photocurrents that can change the operating characteristics of integrated circuits, in turn leads to failures in the transmission of information and to complete failure in emergency situations. The directions of improving the methods of accounting for the influence of atmospheric-optical communication lines on receivers are proposed.
