Furthermore, the terms "first," "second," "third," and the like are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

Furthermore, the terms "horizontal", "vertical" and the like do not imply that the components are required to be absolutely horizontal or pendant, but rather may be slightly inclined. For example, "horizontal" merely means that the direction is more horizontal than "vertical" and does not mean that the structure must be perfectly horizontal, but may be slightly inclined.

The utility model discloses in the implementation process, it uses the FRP material as the reinforcement, nevertheless is different with traditional FRP center reinforcement, and processing has one or more to be heliciform or the cavity hole of SZ shape apart from central point to certain distance apart from central point in the FRP reinforcement, has colored optic fibre or optical fiber ribbon in the hole, at last directly protects one deck PE outer jacket outside FRP. The utility model discloses an optical cable is because there is not loose sleeve pipe and packing rope, so more compact. The proportion of the FRP on the cross section is higher, so that the FRP has better tensile property than the common layer stranded optical cable. Meanwhile, the optical fiber or the optical fiber ribbon is arranged in the hole inside the FRP, and the optical fiber or the optical fiber ribbon is protected by the FRP, so that the optical fiber or the optical fiber ribbon has better pressure-measuring resistance. In consideration of the importance of the extra length of the optical cable, the optical cable can control the extra length in a larger range by adjusting the size of the hollow aperture and the pitch of the spiral or SZ.

In particular, the FRP pultrusion mold is designed to obtain a hollow hole, and the traction device of the pultrusion equipment moves along the axial direction while pulling the FRP and rotates spirally or SZ around the axis of the FRP (the pitch can be adjusted according to the moving speed), so that a spiral or SZ-shaped hollow hole is formed in the FRP reinforcement.
