Optical communication cables. 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, tunnels, collectors, between buildings and constructions, on facades of buildings, inside buildings and constructions, on supports of communication lines and lighting poles.
The cables can contain up to 144 single-mode standard optical fibres (OV type G.652, G.657). The cables are manufactured using fibres produced in the territory of the EAEU member states.
Attenuation coefficient at the operating wavelength, dB/km: for ?=1310nm not more than 0.35; for ?=1550nm not more than 0.22. Cable operation temperature is from minus 40º?
to plus 50º?. Permissible tensile load is not less than 2,5 kN.
