What is FRP? FRP is Fiberglass-Reinforced Plastic. As a strength member, the FRP fiber optic cable reinforcement core is an important component of the fiber optic cable.Its function is to support the fiber unit or fiber bundle and improve the tensile strenath of the fiber optic cable. As a cental strength member (CSM) material, it is generally placed in the center of the fiber optic cable.It is the metal reinforcements that has been used in traditional fiber otpic cables. While the FRP non-metallic reinforcements are increasingly used in various optical cables with their advantages of light weight, high strength,corrosion resistance and long life.

Applications Of FRP. Aramid and FRP can be used together to make non-metallic fiber optic cables, which are mostly used in indoor environments because they are safer. Sometimes it is also used in outdoor environments, such as ADSS fiber optic cables used in power systems. Since there is no metal component in the ADSS cable, it will not be disturbed by lightning, and there is no risk of fireand breakdown at the joint. Steel Wire The advantages of using steel wire as central strength member is that steel wire has high strength and strong resistance to lateral pressure. Therefore,it is usually used in outdoor environments. such as overhead. pipelines,direct burial, and underwater.
