Abstract
The utility model discloses an FFRP belt used for optical cables, which consists of a belt body; the belt body consists of a plurality of fibers and a cementing compound. The plurality of fibers are arranged in the cementing compound; the extension direction of at least one fiber is the same with the extension direction of the belt body; the thickness of the belt body is between 0.1mm and 6mm; the width of the belt body is between 1mm and 120mm; when the optical cables are machined, the FFRP belt is longitudinally packaged outside an optical fiber, or a beam tube, or a cable core, and then an outer sheath is squeezed to play the roles of reinforcing and resisting side compression in the optical cables. The FFRP belt used for optical cables reduces the cost of the optical cables, does not have the problem of hydrogen evolution due to ferrum oxidation, and has excellent low temperature performances; the beam tube can not shrink due to low temperature; moreover, the FFRP belt used for optical cables can be protected against lightning strike when being used in lightning strike areas; and the appearances of the optical cables are rounder.
