Optical cable reinforcement is an important component of optical cable, generally placed in the center of the optical cable, itsrole is to support the optical filber unit or optical iberbundle,improvethetensile strength ofthe optical cable.Tradlitional opticalcables use metal reinfo orcement parts are more and more usedi rcements.FRP non-metallic reinf n various optical cables for their advantages of light weight, high strength, corosion resistance and long life. GFRP fiber optic cable reinfo type of high performance engineering composite mate rcement core (glass fiber) is a new rial, whichis made by pulrusion process after mixing resin as matrix mater orcement mate ial and glass fiber as reinf rial. GFRP non-metalic fiber optic cable reinfo ona rcement overcomes the defects of traditi l metal fiber optic cable reinforcement, has excellent corrosion resistance, lightning resistance, electromagnetic field interference resistance, high tensile strength, light weight, env ironmental protection, energy saving and other significant advantages, is widely used in a variety offiber optic cables.
