Description

Technical Field

[0001] The utility model relates to an improvement on the structure of a communication optical cable, in particular to a double-core tensile-resistant special optical cable. Background Art

[0002] Optical cable is a communication infrastructure that uses optical fiber as a transmission medium. It has excellent communication flux and anti-interference capabilities. With the rapid increase in optical cable production, the application scenarios are also increasing. In indoor environments such as homes, coaxial cables are usually used as the basic layout of communication cables. However, some early home decoration environments are not buried in the walls. When there is a need for network installation, wiring needs to be carried out on the wall surface. Since the outer diameter of the cable is thicker, it is very abrupt on the wall. Therefore, some consumers choose to lay thinner optical cables indoors. The outer diameter of the optical cable is thinner and it is more compatible with the wall background environment. However, due to the many corners of the wall, the optical cable needs to bend with the wall. There will inevitably be pulling during the wiring process, which can easily damage the optical medium. Therefore, the optical cable structure needs to be improved. Utility Model Content

[0003] The purpose of the utility model is to overcome the above-mentioned deficiencies in the prior art and to provide a double-core tensile-resistant special optical cable.

[0004] The technical solution adopted by the utility model to solve the above problems is: the optical cable includes a cable core, a tensile rope, and an outer cladding, the cable core is arranged as two parallel cable structures, the outer cladding is wrapped and fixed on the outside of the two cable cores to form a flat structure, and the outer cladding is also embedded and fixed with a tensile rope arranged parallel to the cable core, and the tensile rope and the cable core are isolated and arranged by the outer cladding. The optical cable structure has two parallel cable cores, and a separate optical fiber line can be arranged in each cable core, which effectively improves the data flux and meets the requirements of indoor wiring. The tensile rope improves the overall tensile strength of the optical cable and improves the overall line elasticity. The outer cladding forms a flat structure, which is convenient for passing through narrow areas, and has certain anti-bending advantages, and has a good protective effect on the optical fiber medium.

[0005] Furthermore, the cable core includes an optical fiber, an inner sheath, a tensile fiber layer and an outer sheath. The optical fiber is wrapped in the inner sheath. The outer portion of the inner sheath is surrounded by a tensile fiber layer. The tensile fiber layer is woven into a mesh by tensile fibers and surrounded by the outer portion of the inner sheath. The outer sheath is surrounded by the outer portion of the tensile fiber layer and fixed to the outer cladding. The optical cable is fixed in the cable core and protected by a sheath. The sheath is double-layered, and a tensile fiber layer is arranged between the sheaths. The cable core is subjected to separate tensile reinforcement and has an elastic protection function, thereby reducing damage to the optical fiber.

[0006] Furthermore, the outer sheath is provided with a recessed strip in the middle between the two cable cores, the recessed strips are arranged oppositely on both sides of the outer sheath, and a tear rope is embedded in the middle of the outer sheath, and the tear rope is located on the bottom connection line of the recessed strips on both sides. With the recessed strip in the middle of the outer sheath and the tear rope, the optical cable can be separated in the middle to form a two-way separable optical cable structure, which is convenient for separate wiring during wiring and can protect the cable core.

[0007] Furthermore, the tensile ropes are provided in two or more pieces and are respectively provided adjacent to one side of the cable core, and the tensile ropes are woven into a rope body by tensile fibers. The tensile ropes can reinforce the cable core separately, avoiding the problem of decreased tensile strength after the cable core is separated.

[0008] Furthermore, the outer layer is made of flame-retardant rubber material and is formed on the outside of the cable core and the tensile rope after hot-melt curing. The outer layer is made of flame-retardant rubber for isolation and protection, which can block combustion and avoid igniting other combustibles while being elastic.

[0009] Compared with the prior art, the utility model has the following advantages and effects: the design is an improvement on the structure of indoor optical cables, with good tensile strength, the dual-core structure can meet the high data throughput requirements of conventional home environments, and can be separated and set up by itself, which is convenient for wiring to different locations after separation, has good tensile strength, improves the elasticity of the optical cable, and has a long service life.
