Abstract
A strength member (202, 302, 402) for use in an optical fiber cable (200, 300, 400) and manufacturing method thereof. The strength member comprises a plurality of reinforced yarns and one or more layers of epoxy resin over the plurality of reinforced yarns, wherein the one or more layers of epoxy resin have a modified surface such that a strength member friction coefficient is between 0.3 to 0.5. The strength member friction coefficient is measured between a surface of a sheath (204, 304, 404) of the optical fiber cable and the modified surface of the one or more layers of epoxy resin. The one or more layers of epoxy resin are blended with at least one of sand crystals and silicon dioxide powder, wherein concentration of the sand crystals or the silicon dioxide powder in the one or more layers of epoxy resin is 50 to 100 phr (Parts-per-Hundred-Resin).
