Fibre-optic cable for laying in soils, including those subject to permafrost deformations, through swamps, at crossings over water obstacles, in cable ducts, on bridges and overpasses, pipes, trays, blocks, The cables can be used for laying on railway contact lines, power transmission line poles, communication line poles and lighting poles, between buildings and structures, on facades of buildings, inside buildings and structures. The cables can contain up to 48 optical fibres. Fibres produced in the territory of the EAEU member states are used in production.
Attenuation coefficient at the working wavelength, dB/km: for ?=1310nm not more than 0.35; for ?=1550nm not more than 0.22. Cable operation temperature is from minus 60º? to plus 70º?.
Permissible tensile load is not less than 2,5 kN.
