What is the role of the FRP cable reinforcement core in a fibre optic cable?

Material is the basis of the cable, no good material is impossible to make a good quality cable. Fibre optic cable reinforcing core structural strength is an important indicator of the mechanical properties of the cable. Fiber optic cable reinforcing core in the structure of the protection of the cable plays a vital role, but also as a fixed cable structural components, in the enhancement of the cable tensile, compressive capacity plays a major role.

　　Fibre optic cable reinforcement core is generally divided into metal reinforcement core and non-metallic reinforcement core. Metal reinforcing core commonly used single steel wire and steel strand. Non-metallic core is commonly used fibre reinforced plastic — — glass fibre GFRP and aramid yarn two types. GFRP used in the core or both sides of the core, aramid yarn used in the core and between the sheath.
