Aging of equipment, climatic changes, the growth of economic activity, the war in the Donbass cause an increased accident rate of the telecommunications network due to the action of numerous destabilizing factors. The operation of network in such circumstances is determined by its sustainability, the maintenance of which consists in preserving the work, when part of the elements fail. The International Telecommunication Union to improve network sustainability has recommended the use of wireless hybrid radio-optical transmission technology FSO/RF in free space; also a promising telecommunications technology, which is positioned to expand the radio frequency spectrum of last mile, consider wireless optical communication Li-Fi. The network architecture with a hybrid topology in addition to time and frequency multiplexing of communication channels supports multiplexing with the separation of signals in conformity with their physical domain and transmission media. Studies have shown an improvement in the sustainability of the telecommunications network of the energy system after the introduction of the wireless hybrid topology through the following actions: 1) increasing branching and redundant of telecommunication lines of the network to increase its network connectivity to the required values; 2) switching in different atmospheric conditions between channels with different physical nature, which causes the choice of a channel with less signal attenuation, fading, energy dissipation; these actions result in an increase of the level of the useful signal and an increase in the signal-to-noise ratio; 3) the use in different atmospheric conditions of radio and optical equipment, with a low value of the partial energy conversion, which leads to a high compatibility of telecommunications facilities.
