Under the cooperation of the structures, the optical cable can deform relatively freely through extrusion according to the actual use environment and requirements, can be suitable for optical cable mounting grooves in different shapes, and greatly improves the use flexibility;
in particular, the method comprises the following steps of,
when the optical cable is embedded in a rectangular groove, two opposite ends of the optical cable are extruded, as shown in fig. 2, when the optical cable is extruded by the groove wall, the end 102 of the inner frame 100 firstly expands towards two sides, and drives the side part of the main body part 101 facing the direction of the groove wall to be in a straightening deformation trend in the expanding process, and the adjacent side part is compressed, so that the optical fiber containing cavity 103 is narrowed and lengthened, and in the deformation process, the special-shaped beam tube 200 can play a good characteristic of adaptive deformability, so that the side edge of the special-shaped beam tube is changed from the original straight state to the arc state, and the optical fiber wires 201 arranged in parallel along the axial direction of the optical cable in the side edge are easily rearranged along with the side edge and cannot be directly extruded by the groove wall;
