Results of experimental study of copper conductor cable resistance to low ambient temperature
The paper describes the tests of communication cable and signal and blocking cable for resistance to temperature factors, specifically to low temperature, in order to assess their applicability for installation and operation in the Extreme North and Siberia regions. The results of cable tests for resistance to temperature cycling and bending at subzero temperatures are presented.

Choice of the number of redundant optical fibers in communication cables
The ability of the network to perform the specified functions under certain conditions for a given time is one of the main tasks in the design, construction and operation of communication lines. In the article, optical communication lines are divided into, conventionally speaking, traditional ones and laid in hard-to-reach terrain. To the last case it is necessary to attribute underwater optical cables, suspended and underground OK, laid in places, access to which is difficult or impossible for the maintenance personnel. The paper deals with the redundancy of optical fibers for communication cables laid in hard-to-reach terrain.

Fire safety composite materials based on olefin copolymers. Directed control of prosessing, physicomechanical and thermophysical properties
Flame retardant polymer composites based on olefin copolymers were studied with the aim of controlled regulation of their processing and some performance characteristics. The methods developed for such regulation of properties are described. The dependences of rheological, physical-and-mechanical and thermal-and-physical properties, as well as oxygen index on the polymer compound formulation were studied with the chemical composition, dispersity of fire-retardant fillers and the effect of modifying additive taken into account.
