3.5mm FRP Reinforced Core For Optic Cable
The strength member is structurally vital and protective for cables. The structural strength of the strength member is one important indicator for the mechanical properties of fiber optic cables. As the fastening component, the strength member supports the majority of structural strength of fiber optic cables and plays a vital role in enhancing the tensile strength and impact strength.
Currently used strength member for fiber optic cables are metallic and non-metallic strength member. Single steel wire or steel strand is frequent working as metallic reinforcement, while non-metallic strength member is from fiber glass reinforced plastic (FRP rod) or aramid yarn or aramid rod. FRP is often located in the central or two flanks of cables, aramid fiber is in the central or between two sheaths.
