ANALYSIS OF THE OSCILATIONS OF FIBER OPTIC CABLES INSTALLED IN TUNNELS, UNDER SEISMIC IMPACTS TAKING INTO ACCOUNT SPECIFIC CABLE ATTACHMENT ON TRANSMISSION POLES

A.G. Koryakin, Cand. Sc. (Engineering), Head of Test Laboratory, Deputy Manager of Department, OJSC VNIIKP;

D.S. Kholodny, Cand. Sc. (Physics and Mathematics), Associate Professor of Physics and Electrical Materials and Components Technology Department of FGBOU VO “NIU “MEI”

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.

ANALYSIS OF THE BROADBAND ACCESS TECHNILOGIES BASED ON MULTI-PAIR LAN CABLES AND THE REQUIREMENTS FOR THEM

V.B. Popov, Cand Sc. (Engineering), Professor of Department of Communication Lines and Measurements in Communication Engineering of FGBOU VO “Povolzhskiy State University of Telecommunications and Informatics”;

I.S. Sherstnikov, Chairman of the Board of Directors of JSC “Samara Cable Company”

Abstract. The analysis of broadband access technologies based on multi-pair LAN cables is presented. It is shown that the developed set of measures related to the technology of cable core twisting and application of a screen and a protective polymer sheath makes it possible to ensure the compliance with the norms for the electrical characteristics of transmission and mutual influences of LAN cables that meet the requirements for category 5e.

Key words: multi-pair LAN cables, broadband access, xDSL technology, cable core twisting, twisting machines, screen, JSC “Samara Cable Company”.

CABLE RUBBERS. CURRENT STATE AND DEVELOPMENT TRENDS

K.A. Zvezdenkov, Cand. Sc. (Engineering), Head of Laboratory, OJSC VNIIKP;

I.B. Peshkov, Dr. Sc. (Engineering), Professor, Chief Research Scientist, OJSC VNIIKP

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.
