Abstract. The article presents the calculation results of oscillations of fiber optic cables installed in tunnels and ducts or other confined spaces under seismic impacts.
The cable attachment points subjected to transverse vibrations under the action of inertial forces during earthquakes are considered as different boundary conditions. After the calculation of the optical cable response to the seismic impact the maximum displacement and acceleration amplitudes along the cable length are determined.
Key words: overhead lines of optical communication cables, joint oscillations of conductors and transmission poles, dynamic interaction, vibration frequency calculation.

Abstract. The article describes the milestones of the cable industry development in the USSR, and afterwards in Russia. Consideration is given to the experience of using rubbers in cable constructions and to the development of rubber processing technology in the 20st century at the cable plants. Special attention is devoted to the promising rubber mixing technology with the Sibkabel plant production (Tomsk) taken as an example. Information about the cable rubber consumption volumes and the expected consumption of rubber types used is given.
Key words: cable rubbers, rubber mixing, vulcanization, cable rubber types, insulation, sheath, ethylene propylene rubber.
