Optical fire-resistant communication cable is designed for transmission of digital communication signals, is used for laying in soils of 1-3 groups, in cable ducts, blocks, inside buildings, tunnels, collectors with increased requirements to mechanical properties of the cable and operability in fire conditions. The cable has a modular optical core consisting of a central power element around which optical modules and other elements (if necessary) are twisted, the total number of optical fibres in the cable is up to 144 pieces.
The intramodule space is filled with hydrophobic filler along the entire length of the cable. The protective cover of the cable consists of steel wires and outer sheath of halogen-free polymer compositions
