Description

Technical Field

[0001] This utility model relates to the field of micro indoor wiring optical cable technology, and in particular to a novel central tube type micro indoor wiring optical cable. Background Technology

[0002] With the development of information and communication, the volume of information and communication is increasing, so more cables need to be accommodated in a limited space. However, the available channels and conduits for cabling are limited, especially in cases of old house renovation and cabling upgrade. During construction, there are often other lines in the channels or conduits, and the available cabling space is even smaller. Therefore, transmission cables need to be thinner and more flexible to facilitate construction while maintaining basic performance.

[0003] Currently, commonly used indoor fiber optic cabling often involves wrapping each individual optical fiber with a tight sheath of 0.9mm or 0.6mm, and then bundling them together to form a cable. This method results in several drawbacks. First, because each optical fiber has its own protective sheath, the overall cable size is larger and feels stiffer. Second, the presence of the tight sheath requires additional stripping of the sheath during splicing, making the process more complicated. Third, many cable trays are prone to damage from rodents and other organisms, and areas where cables are laid, such as low-voltage wells, are also prone to dampness or water seepage. Traditional fiber optic cabling does not adequately address these issues, making the cables susceptible to damage over long-term use.

[0004] Therefore, we propose a novel central tube-type miniature indoor wiring optical cable. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel central tube-type miniature indoor wiring optical cable.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A novel central tube type miniature indoor wiring optical cable includes an outer sheath, on the inner side of which a water-blocking glass yarn is provided, and a wiring assembly is fixedly provided on the inner side of the water-blocking glass yarn. A tear cord is fixedly provided at the bottom inside the water-blocking glass yarn.

[0008] The water-blocking glass yarn has an inner sheath two fixedly installed inside it. The inner sheath two is fixedly installed inside the outer sheath one. The outer sheath one is the outer sheath of the optical cable, providing the outermost layer of protection against pressure and abrasion. The water-blocking glass yarn is a glass yarn with water-blocking function, which provides the overall tensile strength of the optical cable. At the same time, the properties of the glass yarn can effectively prevent rodent bites. Due to the addition of water-blocking materials, it can effectively prevent water damage. It can also be replaced or partially changed to other reinforcing materials such as aramid as needed. The tear rope is set to facilitate the stripping of the outer sheath during construction.

[0009] The inner sheath 2 is fixedly provided with aramid + water-blocking yarn on its inner side. The aramid + water-blocking yarn is fixedly placed inside the water-blocking glass yarn. The inner sheath 2 is the sheath of the inner sub-tube, which protects the entire optical fiber bundle separately. The double sheath provides stronger protection.

[0010] The aramid + water-blocking yarn contains a colored optical fiber, which is a commonly used 250μm colored bare fiber. The aramid + water-blocking yarn provides separate tensile strength for the sub-tube and acts as a buffer between the optical fibers, thus providing better protection for the optical fibers. The water-blocking yarn can provide water-blocking performance inside the sub-tube.

[0011] The aramid + water-blocking yarn contains 12 different colored optical fibers, which are fixedly installed inside the inner sheath. These colored optical fibers are communication optical fibers that are protected. They are bare colored optical fibers without a tight sheath structure. By providing 12 different optical fiber colors and marking dots on the optical fibers, it can support the use of optical cables with 12 or more colors. The colored sheath facilitates the visual identification of the cable. The sheath color can be determined according to the main optical fiber type in the optical cable, and different numbered identifiers can be marked to display the required information.

[0012] Compared with the prior art, this utility model provides a novel central tube-type miniature indoor wiring optical cable, which has the following beneficial effects:

[0013] 1. This utility model, through the installation of cabling components, presents a newly designed optical cable that uses commonly used 250μm colored bare fiber for information transmission. A sub-tube filled with reinforcing elements, water-blocking materials, or other necessary fillers secures and protects the entire fiber bundle. The sub-tube is fitted with a flexible and reliable outer sheath, and a reliable reinforcing element fills the space between the sub-tube and the outer sheath. Because all the optical fibers are fixed and protected within the sub-tube, the overall outer diameter of the cable is smaller, occupying less space. Furthermore, due to the small outer diameter and double-layer sheath, the internal filling is quite substantial. Therefore, while providing excellent protection for the optical fibers, it is also very flexible, lightweight, and easy to install. This type of cable is ideal for indoor cabling, and direct connection of 250μm to 250μm optical fibers is also very convenient. Its convenient and compact design makes it an ideal alternative to traditional indoor optical cables when smaller diameters are required. The soft and reliable outer sheath and double-layer sheath structure make installation easier in space-constrained areas. The colored bare fiber bundles do not require separate fiber stripping, making it simple to use. The water-blocking glass yarn and other reinforcing materials between the two sheaths and in the inner sheath improve the tensile strength of the optical cable. The use of glass yarn effectively reduces the risk of rodent bites, and the water-blocking powder effectively waterproofs the entire cross-section, making it resistant to humid environments. This optical cable supports the use of 12 or more colors by providing 12 different fiber colors and markings on the fibers. The colored sheath facilitates visual identification of the cable, and the sheath color can be determined according to the main fiber type in the optical cable, with different numbering marks indicating the required characteristics.

[0014] 2. The optical cable of this utility model is thinner, more flexible, occupies less space, and is easier to install. At the same time, the structure can also meet the requirements of rodent resistance and waterproofing, making it more suitable for the new needs of indoor wiring.

[0015] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description
