What model of fiber optic cable reinforcing core
FRP optical cable core is a non-metallic strength member widely used in fiber optic cables to provide structural support and tensile strength. It is lightweight, corrosion-resistant, and non-conductive, making it ideal for use in environments where metal components are unsuitable. (1)Lightweight and high-strength Relative density is between 1. 0, which means 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of. As one of the structural components of fixed optical cable, the FRP reinforcing core plays an important role in strengthening the tensile and compressive capacity of optical cable.
