Optical communication cables. Fibre-optic cable for laying in cable ducts, in cable trays, channels, collectors, tunnels, on bridges, overpasses, in pipes (including pneumatic laying in special protective plastic pipes), power facilities, on the facades of buildings, inside buildings and structures, for suspension on the supports of communication lines, power 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 720 optical fibres. 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 60º?
to plus 70º?. Permissible tensile load is not less than 1,0 kN.
