  • Strength members for the reinforcement of optical fibre cables
    Patent number: 4269024
    Abstract: A continuous elongate strength member for reinforcing an optical fibre cable consists of an assembly of aromatic polyamide filaments impregnated with a synthetic resin, in which the filaments are individually coated with the resin, and the filaments of at least an outer layer of the assembly are helically stranded. The impregnation is carried out by separating the filaments and immersing them in a low viscosity dispersion of the resin in a liquid medium; the filaments are then stranded, and the resin is cured. Apparatus for manufacturing the strength member and various forms of cable incorporating one or more strength members, are described.
