[0001] The invention belongs to the technical field of composite optical fiber network cables, and in particular relates to a bend-resistant and environment-friendly composite optical fiber network cable. Background Art

[0002] Composite fiber optic network cable usually refers to a communication cable that combines the functions of optical fiber and cable. It is also called composite optical cable. This cable can transmit both optical signals and electrical signals. It has the advantages and characteristics of high-speed transmission, stable and reliable, integrated wiring, and strong anti-interference ability.

[0003] In current wiring practices, the laying of network cables and optical fibers often requires two separate threading operations, which not only increases the complexity and time cost of construction, but also increases the difficulty of wiring. In particular, optical fibers are easily obstructed during the threading process due to their physical properties and cannot withstand strong bending. Summary of the invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of the present invention is to provide a bend-resistant and environmentally friendly composite optical fiber network cable. After the Category 6a network cable and the dual-core optical fiber are wrapped in the same sheath through a composite process, the network cable and the optical fiber can be used independently, and the signal transmission does not interfere with each other, so as to solve the problem that the network cable and optical fiber wiring need to be passed through twice.

[0005] To achieve the above object, the present invention provides the following technical solutions:

The polymer material cladding is sleeved on the outer surfaces of the two silicone coating layers, the imitation olefin yarn is filled between the polymer material cladding and the silicone coating layer, and the polymer material cladding is interspersed between the flame-retardant and environmentally friendly sleeve and the first polyester film.

[0010] Preferably, the insulating layer and the copper conductor are arranged between the cross skeleton and the second polyester film in the form of a combination of four pairs of eight-core twisted pairs.

[0011] Preferably, the copper conductor uses a thickened 4N oxygen-free copper core, and the transmission rate is 10 Gbps.

[0012] Preferably, the flame-retardant and environmentally friendly sleeve is made of super-tough and tensile-resistant environmentally friendly PE.

It is adapted to the needs of modern networks, and the weak current wiring can be completed at one time during wiring. It can also solve the problem that the existing optical fiber is difficult to thread and cannot be strongly bent.

[0017] (2) By arranging quartz optical fiber, silicone coating, imitation olefin yarn and polymer material cladding, the transmission capacity and transmission efficiency can be further improved by arranging quartz optical fiber, and the silicone coating can be used to protect the surface of the quartz optical fiber from moisture and external force abrasion, while improving the anti-microbending performance of the quartz optical fiber, reducing the additional microbending loss of the optical fiber, and ensuring the stability and reliability of the optical fiber during transmission.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] Embodiment 1:

[0026] See also Figure 1 - Figure 5 As shown, a bend-resistant and environment-friendly composite optical fiber network cable comprises:

[0027] Flame retardant environmentally friendly cover 1;

[0028] A first polyester film 2 is arranged in the flame-retardant and environmentally friendly sleeve 1, a double-core optical fiber composite cable 3 is arranged between the first polyester film 2 and the flame-retardant and environmentally friendly sleeve 1, a sheath 4 is arranged in the first polyester film 2, a second polyester film 5 is arranged in the sheath 4, a cross frame 6 is arranged in the middle of the second polyester film 5, four groups of copper conductors 8 are arranged in groups of two at equal distances between the cross frame 6 and the second polyester film 5, the outer surfaces of the copper conductors 8 are all provided with an insulating layer 7, and a tear rope 9 is arranged on one side of the second polyester film 5;

[0029] The dual-core optical fiber composite cable 3 includes a polymer material cladding 31, an imitation flame retardant yarn 32, a silicone coating 33 and a quartz optical fiber 34. There are two quartz optical fibers 34 and two silicone coatings 33, and the two silicone coatings 33 are respectively sleeved on the outer surfaces of the two quartz optical fibers 34. The polymer material cladding 31 is sleeved on the outer surfaces of the two silicone coatings 33. The imitation flame retardant yarn 32 is filled between the polymer material cladding 31 and the silicone coating 33. The polymer material cladding 31 is interspersed between the flame retardant and environmentally friendly sleeve 1 and the first polyester film 2.

[0030] As can be seen from the above, the category 6a network cable and the dual-core optical fiber composite cable 3 composed of the sheath 4, the second polyester film 5, the cross skeleton 6, the insulating layer 7, the copper conductor 8 and the tear rope 9 are wrapped in the same flame-retardant and environmentally friendly sheath 1 through a composite process. When in use, the category 6a network cable and the dual-core optical fiber composite cable 3 can be used independently, and the signal transmission does not interfere with each other. The flame-retardant and environmentally friendly sheath 1 is made of super-tough tensile-resistant environmentally friendly PE. Through the protection of the flame-retardant and environmentally friendly sheath 1, the problem that traditional optical fibers are easily damaged and cannot be strongly bent is solved. When using, users can choose to connect to the network cable or the dual-core optical fiber composite cable 3, or they can be used separately or at the same time. It is adapted to modern network needs, and weak current wiring can be completed at one time during wiring, and it can solve the problem that existing optical fibers are difficult to thread and cannot be strongly bent.

[0031] Embodiment 2:

[0032] refer to Figure 1 , Figure 4 and Figure 5 As shown, the dual-core optical fiber composite cable 3 includes a polymer material cladding 31, an imitation flame retardant yarn 32, a silicone coating 33 and a quartz optical fiber 34. Two quartz optical fibers 34 and two silicone coatings 33 are provided in each of the quartz optical fibers 34, and the two silicone coatings 33 are respectively sleeved on the outer surfaces of the two quartz optical fibers 34, the polymer material cladding 31 is sleeved on the outer surfaces of the two silicone coatings 33, the imitation flame retardant yarn 32 is filled between the polymer material cladding 31 and the silicone coating 33, and the polymer material cladding 31 is interspersed between the flame retardant and environmentally friendly sleeve 1 and the first polyester film 2.

[0033] As can be seen from the above, by setting two mutually parallel quartz optical fibers 34, the transmission capacity and transmission efficiency can be further improved, and the outer surface of the quartz optical fiber 34 is coated with a silicone coating layer 33 to protect the surface of the quartz optical fiber 34 from being scratched by humid gas and external force, while improving the anti-microbending performance of the quartz optical fiber 34, reducing the additional microbending loss of the optical fiber, and ensuring the stability and reliability of the optical fiber during transmission. The imitation olefin yarn 32 is filled between the polymer material cladding 31 and the silicone coating layer 33 to enhance the strength of the optical cable and prevent the optical cable from breaking when subjected to external force. At the same time, the imitation olefin yarn 32 can also improve the wear resistance and corrosion resistance of the optical cable, extend the service life of the optical cable, and ensure the high performance, reliability and safety of the optical cable.

[0034] Preferably, the two quartz optical fibers 34 together form a dual-core optical fiber, and the transmission rate is 100 Gpbs.

[0035] As can be seen from the above, by setting up the quartz optical fiber 34, the high bending resistance and high strength characteristics of the network cable are achieved. The quartz optical fiber 34, with its excellent physical properties, ensures that the network cable can still maintain excellent transmission performance and stability in a complex and changeable wiring environment. Whether it is facing frequent bending or high-intensity pulling force, it can easily cope with it, thereby bringing users a more reliable network connection experience.

[0036] Embodiment three:

[0037] refer to Figure 1 , Figure 2 and Figure 3 As shown, the insulating layer 7 and the copper conductor 8 are arranged between the cross frame 6 and the second polyester film 5 in the form of a combination of four pairs of eight-core twisted pairs;

[0038] The sheath 4, the second polyester film 5, the cross skeleton 6, the insulating layer 7, the copper conductor 8 and the tear cord 9 together constitute the Category 6A network cable.

[0039] As can be seen from the above, the super six-category network cable composed of the sheath 4, the second polyester film 5, the cross frame 6, the insulating layer 7, the copper conductor 8 and the tear rope 9, and the insulating layer 7 and the copper conductor 8 are arranged between the cross frame 6 and the second polyester film 5 in the form of a combination of four pairs of eight-core twisted pairs, and its transmission rate can reach 10Gbps. The insulating layer 7 is made of high-quality high-density polyethylene material, which not only has excellent insulation performance, but also can effectively improve the durability and stability of the network cable. At the same time, the addition of the sheath 4 and the flame-retardant and environmentally friendly sleeve 1 further enhances the stability and safety of the entire network cable structure. The synergistic effect of these components has jointly created a super six-category network cable with excellent performance, safety and reliability.

[0040] Preferably, the copper conductor 8 uses a thickened 4N oxygen-free copper core, and the transmission rate is 10 Gbps;

[0041] The flame retardant and environmentally friendly cover 1 is made of super-tough and tensile-resistant environmentally friendly PE;

[0042] The two quartz optical fibers 34 together form a dual-core optical fiber, and the transmission rate is 100 Gpbs.

[0043] As can be seen from the above, the copper conductor 8 is made of thickened 4N oxygen-free copper core. In power grid transmission or signal transmission applications, this can ensure efficient and lossless transmission of signals and improve the performance of the overall system.

[0044] Furthermore, the present invention is designed and applied in the integrated wiring of government, enterprises and residences and in the 5G signal transmission environment. The super six-category network cable and the dual-core optical fiber composite cable 3 composed of the sheath 4, the second polyester film 5, the cross skeleton 6, the insulating layer 7, the copper conductor 8 and the tear rope 9 are wrapped in the same flame-retardant and environmentally friendly sheath 1 through a composite process. When in use, the construction personnel can easily peel off the sheath 4 by grabbing the tear rope 9 and pulling it hard, so as to carry out subsequent wiring or maintenance work. The super six-category network cable and the dual-core optical fiber composite cable 3 are independent of each other in this structure, and the signal transmission does not interfere with each other. Users can flexibly choose to connect the network cable or the dual-core optical fiber composite cable 3 according to their actual needs, and can even use both at the same time to meet the diversified needs of modern networks. This design not only enhances the practicality of the cable, but also provides users with more choices.

[0045] The use of flame-retardant and environmentally friendly sleeve 1 solves the problem that traditional optical fibers are easily damaged and cannot be strongly bent. Its ultra-tough and tensile properties provide solid protection for the cables, making them more stable and reliable during transmission. At the same time, the application of this environmentally friendly material is also in line with the concept of sustainable development in modern society.

[0046] In addition, the insulating layer 7 is made of high-quality high-density polyethylene material, which cooperates with the sheath 4 and the flame-retardant and environmentally friendly sheath 1 to form a cable system with extremely high structural stability. This design not only enhances the durability of the cable, but also ensures the reliability and stability of signal transmission;

[0047] In general, the present invention successfully solves the problems of existing optical fibers being difficult to thread and unable to be strongly bent through innovative design and advanced material applications, bringing a new solution to the power grid transmission environment. During wiring, weak current wiring can be completed at one time, greatly improving wiring efficiency and cable utilization.
