The small-sized fibre-optic cable on the basis of a central tube is intended for laying in cable ducts, pipes, blocks, collectors, inside buildings and constructions/ The optical cable contains a core in the form of a central tube, inside which up to 48 single-mode or multimode optical fibres are located. The inner space of the tube is filled with hydrophobic compound or other water-blocking material along its entire length. An inner sheath of polyethylene or polymer compound may be applied over the core. A galvanised steel wire armour is overlaid on top of the core or sheath. The armour is filled with a thixotropic hydrophobic compound or other water-blocking material along its entire length. The armour is covered with a polymer sheath made of polyethylene or polymer compound not spreading combustion in single or group laying
