For laying in cable ducts, pipes, trays, blocks, tunnels, collectors, on bridges and overpasses; Inside buildings; For laying in the ground. The cable contains a central steel optical module with loosely laid fibres.
The free space in the optical module is filled with hydrophobic gel. Optical fibres in the module are grouped into bundles (if the number of fibres is more than 12).
Each fibre bundle is wrapped with coloured synthetic thread. A steel wire armour is spirally applied to the central optical module.
Water blocking threads are laid under the armour. The armour is covered with a sheath made of a polymer composition that does not spread combustion and does not emit corrosive-active gaseous products during combustion and smouldering.
Resistant to UV radiation; excellent protection against rodents; retention of fire resistance and serviceability not less than 180 minutes.
