Strength member for fiber optic cables, usually located at the center of fiber optic cables, is one important component of fiber opticcables by supporting optic fiber bundle and enhancing cables tensile strength. Traditionally strength member is metal wire. Non-metallicFRP strength member are widely used in various fiber optic cables due to their advantages like low weight, high strength, anti-corrosionand long service life.
