Optical communication cables. Fibre-optic universal cable with the possibility of using protective and power threads for laying in cable ducts, in cable trays, channels, collectors, tunnels, on bridges and overpasses, in pipes (including pneumatic laying method), power facilities, on facades of buildings, inside buildings and structures, for suspension on communication line supports, power transmission lines, lighting poles, between buildings and structures, by methods of coiling, connection and attachment to external load-bearing power elements.
The cables can contain up to 144 optical fibres. Fibres produced in the territory of the EAEU member states are used in production.
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 60º?
to plus 70º?. Permissible tensile load is not less than 1,0 kN.
