A laboratory setup has been created that makes it possible to conduct comprehensive studies of the influence of atmospheric discharges on the transmission of quantum keys over optical communication lines. The effect of a strong action of an electric field from a charged water aerosol on the polarization of radiation passing along an all-dielectric fiber-optic cable has been found. The dynamics of changes in the optical fiber arising from the action of electrostatic fields of a charged cloud, preceding the electrical breakdown of air, has been registered. An analysis of the need to protect quantum networks from the effects of atmospheric discharges is presented.
