DETAILED DESCRIPTION

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods:

[0027] like Figure 1 , Figure 2As shown, the indoor optical fiber composite cable structure includes an optical fiber core 1, a non-metallic strength member 2, a cable core filler 8, a copper wire 5, a first sheath 9, a second sheath 6 and a third sheath 3. The optical fiber core 1 and the non-metallic strength member 2 form an optical fiber unit 4 through the third sheath 3, and the soft copper wire 5 forms a copper wire unit 7 through the second sheath 6, and the optical fiber unit 4, the copper wire unit 7 and the cable core filler 8 are placed in the first sheath 9.

[0028] like Figure 1 As shown, as one of the options, when there is at least one group of optical fiber units 4 and copper wire units 7 in the first sheath 9, it is a first optoelectronic composite cable A.

[0029] In this embodiment, the optical fiber unit 4 and the copper wire unit 7 are arranged in an upper and lower order, and the copper wire unit 7 is placed above the optical fiber unit 4 .

[0030] The optical fiber unit 4 has a rectangular cable shape, with four corners being rounded, at least two of which are in contact with the first sheath 9, and two symmetrical V-shaped openings are provided.

[0031] The copper wire unit 7 is in the shape of a round cable, and has two copper wires 5 therein, at least two sides of which are in contact with the optical fiber unit 4 and at least two sides of which are in contact with the first sheath 9, and also have two V-shaped openings.

[0032] like Figure 2 As shown, as one of the options, when there are at least two groups of the optical fiber units 4 and the copper wire units 7 in the first sheath 9, it is a second optoelectronic composite cable B.

[0033] In this embodiment, the two groups of optical fiber units 4 are staggered and each has a gap for placing the copper wire unit 7. One group of copper wire units 7 is located on the left side of the optical fiber unit 4 and parallel to it, and the other group of copper wire units 7 is located on the right side of the optical fiber unit 4 and parallel to it.

[0034] The optical fiber unit 4 has the same appearance as the above optical fiber unit 4, except that the two groups of optical fiber units 4 each have one side in contact with the first sheath 9, and at least one side in contact with each other.

[0035] The copper wire unit 7 is a separate round cable, which is different from the above copper wire unit 7. Each of the copper wire units 7 has only one copper wire 5, and at least one copper wire unit 7 is in contact with the optical fiber unit 4 on at least one side. Both groups of copper wire units 7 are not in contact with the first sheath 9.

[0036] Furthermore, in the above two options, in order to prevent the optical fiber unit 4 and the copper wire unit 7 from being loosely arranged, a gap is left for placing the cable core filler 8.

[0037] like Figure 1-Figure 2As shown, in this embodiment, the optical fiber unit 4 is capable of processing a large amount of data traffic, wherein the non-metallic reinforcement member 2 does not have the problem of iron oxidation and hydrogen evolution, thereby ensuring that it will not be corroded by acidic liquids, and can be used in areas with frequent lightning strikes when necessary, and the third sheath 3 is made of a low-smoke halogen-free material, which will not release toxic or corrosive gases when exposed to fire, and has excellent low-temperature resistance, lateral pressure resistance, and good bending properties.

[0038] In this embodiment, the copper wire unit 7 solves the problem of equipment power consumption, wherein the soft copper wire 5 is not only highly flexible but also has excellent conductivity. The polyvinyl chloride material used in the second sheath 6 ensures good insulation at all times under different temperatures or humidities due to its excellent electrical properties and weather resistance.

[0039] Furthermore, by integrating the optical fiber unit 4 and the copper wire unit 7 into one, the problems of broadband access, equipment power consumption, and signal transmission are solved simultaneously, avoiding secondary wiring. The first sheath 9 is also made of polyvinyl chloride material, which has good softness and flexibility, as well as small size, easy connection, and convenient disassembly, which is extremely suitable for indoor installation.

[0040] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
