Please refer to FIG. 1 . FIG. 1 is a schematic cross-sectional view of a non-metal rodent-proof optical cable according to some embodiments. The non-metal rodent-proof optical cable includes at least one optical transmission unit 10 , a first outer covering layer 20 , a plurality of protection members 30 and a second outer covering layer 40 .

The optical transmission unit 10 is an optical fiber unit bundle, and each optical transmission unit 10 (fiber unit bundle) may have at least one optical fiber core wire 10a, which can be used to transmit signals in single or plural. Further, the optical transmission unit 10 includes a single-core or multiple-core optical fiber. In some embodiments, the optical transmission unit 10 is covered with 2, 4, 6, 8, 12, 16, and 24 optical fiber core wires 10a. Here, the light transmission unit 10 is, for example, but not limited to, dyed optical fibers, ribbon optical fibers, micro-clustered optical fibers, glue-filled optical fibers, or any combination thereof.

The first outer covering layer 20 is located outside the light transmission unit 10 and covers the light transmission unit 10 . The outer shape of the first outer covering layer 20 is in the shape of a tube, that is, the cross section of the first outer covering layer 20 is circular, oval or other suitable shapes, and the circular or elliptical first outer covering layer 20 is used to cover the light. The transmission unit 10 can effectively protect the internal light transmission unit 10 and facilitate wiring inside. In addition, the circular tube body bears the same pressure at all points, so that the light transmission unit 10 can be fully protected. Here, the entirety formed by the first outer covering layer 20 and the optical transmission unit 10 may also be referred to as a sub-cable. In some embodiments, the first outer covering layer 20 may be formed of plastic, rubber, or other polymer materials, but the present invention is not limited thereto.

The protection member 30 is located outside the first outer covering body layer 20 and surrounds the first outer covering body layer 20 . Here, the protection member 30 is disposed on the first outer covering body layer 20 and located at the periphery of the first outer covering body layer 20 . In addition, each of the protection members 30 is closely arranged together, and is arranged around the periphery of the first outer covering layer 20 . In some embodiments, the protective member 30 is glass fiber reinforced plastic (GFRP, Glass Fiber Reinforced Plastic) or Kevlar fiber reinforced plastic (KFRP, Aramid fiber reinforced Plastic). Since KFRP or GFRP is a reinforced aramid synthetic fiber or glass fiber, both fibers are protected by an outer resin coating to increase their strength and stiffness. Therefore, when the protection member 30 of the present invention is located outside the first outer covering layer 20, its mechanical strength properties are superior to those of general non-metallic optical cables, and at the same time, the barrier capability of preventing rodent bites, insects and ants is more excellent. The optical transmission unit 10 has the protection ability to prevent the mouse from biting the optical cable.

The second outer covering layer 40 is located outside the protector 30 and covers the protector 30 . The outer shape of the second outer covering layer 40 is in the shape of a tube, that is, the cross-section of the second outer covering layer 40 is circular, oval or other suitable shapes, and the second outer covering layer 40 is covered and protected by a circular or elliptical second outer covering layer 40 . The component 30 can effectively protect the internal light transmission unit 10 and the protective component 30 , and also facilitate the wiring of the protective component 30 in the interior thereof, and increase the stability of the arrangement of the protective component 30 in the interior, so that the protective component 30 can be evenly arranged. They are arranged on the periphery of the first outer covering layer 20 without interlacing with each other. Furthermore, since the circular tube body of the second outer covering layer 40 is subjected to the same pressure at all points, the protection member 30 can be fully protected. In some embodiments, the second outer covering layer 40 may be formed of plastic, rubber or other polymer materials, but the present invention is not limited thereto.

Please refer to FIG. 2 and FIG. 3 . FIG. 2 is a schematic diagram (1) of a tensile body according to some embodiments. FIG. 3 is a schematic diagram (2) of a tensile body according to some embodiments. In some embodiments, the non-metal rodent-proof optical fiber cable of the present invention further includes at least one tensile body 50 , which is located outside the first outer coating layer 20 and surrounds the first outer coating layer 20 . Further, in this embodiment, the tensile body 50 is interposed between the protector 30 and the first outer covering body layer 20 . Here, the preferred material of the tensile body 50 is glass fiber or aramid synthetic fiber to increase its tensile strength. In other embodiments, the non-metal rodent-bite-proof optical fiber cable of the present invention further includes at least one tensile body 50 , which is located outside the protection member 30 and surrounds the protection member 30 and surrounds the second outer covering layer 40 (shown in Figure 3). Further, in this embodiment, the tensile body 50 is interposed between the protector 30 and the second outer covering layer 40 . However, the position setting of the aforementioned tensile body 50 is only an example. In other embodiments, a two-layer tensile body 50 may also be provided. In addition, the tensile body 50 is positioned between the first outer covering body layer 20 and the protector 30 and between the protecting member 30 and the second outer covering body layer 40, respectively.

Please refer to FIGS. 4 to 6 . FIG. 4 is a schematic cross-sectional view of a non-metal rodent-proof optical cable according to another embodiment. FIG. 5 is a schematic diagram (1) of a tensile body according to another embodiment. FIG. 6 is a schematic diagram (2) of a tensile body according to another embodiment. The only difference between this embodiment and the previous embodiment is that the non-metallic rodent-biting optical fiber cable of this embodiment further includes a central tensile body 60 , and other structures are the same as those in the previous embodiment, which will not be repeated here.

The central tensile body 60 is located within the first outer cover layer 20 and is surrounded by the light transmission unit 10 . Further, the optical transmission unit 10 is surrounded by the central tensile body 60, so that when the central tensile body 60 is located in the first outer cover layer 20, it can be approximately located in the sub-cable (the first outer cover layer 20 and the optical fiber) at the center of the whole formed by the transmission unit 10). In some embodiments, the central tensile body 60 is in the shape of a tube, and further, the cross section of the central tensile body 60 is in a circle, an ellipse or other suitable shapes. Here, the central tensile body 60 is made of glass fiber bundle reinforced plastic or Kevlar fiber bundle reinforced plastic, or other fiber materials with high tensile strength and high tensile coefficient. In addition, the central tensile body 60 can not only increase the tensile strength, but also prevent the optical transmission units 10 in the sub-cable from intertwining with each other, and at the same time, the function of easy extraction of the optical transmission units 10 can be achieved.

To sum up, in some embodiments, the non-metal rodent-proof optical fiber cable of the present invention is surrounded by the protection member outside the first outer covering layer, as a mechanism for protecting the sub-cable and enhancing the non-metal rodent-proof fiber optic cable Strength, such as tensile strength, compressive strength and bending strength, also has the ability to prevent rodents and insects from biting off the optical transmission unit. It solves the communication instability problem of the fiber optic backbone line of the fiber-to-the-home or fiber-optic building, and solves the serious problem that the fiber optic line is constantly being bitten by mice and the lightning strike conduction problem between the equipment and the equipment.

Although the technical content of this creation has been disclosed above with preferred embodiments, it is not intended to limit this creation. Anyone who is familiar with this technique, any changes and modifications made without departing from the spirit of this creation, should be covered in this creation. Therefore, the scope of protection of this creation should be determined by the scope of the appended patent application.
