Description

Technical Field

[0001] This utility model relates to transmission cables, and in particular to an invisible optical cable structure for introducing optical fibers from outdoors into indoor spaces. Background Technology

[0002] With the development of information technology and the widespread use of optical fiber, people are increasingly using fiber optic equipment in their lives and offices. However, since most residential and office buildings are not pre-installed with conduits for retrofitting, optical fiber must be introduced from outdoors into the room, and then into each room. This is the FTTR (Fiber to the Room) fiber optic access technology. Currently, FTTR uses single-core or two-core invisible optical cables as transmission cables. When single-core or two-core optical cables cannot meet the needs, multiple optical cables are laid simultaneously. This not only increases the difficulty of construction but also affects the interior decoration. At the same time, in order not to obstruct or affect the interior decoration, invisible optical cables need to be routed along wall corners, cabinet edges, door seams, etc. However, since invisible optical cables are transparent and inconspicuous, users inevitably bump or squeeze the cables in their daily lives, thus affecting the safety and stability of the cables. Utility Model Content

[0003] The purpose of this invention is to provide an invisible optical cable structure with better structural strength, more diverse usage methods, and greater convenience, so as to reduce installation difficulty, improve construction efficiency, and enhance the safety and stability of optical cable use.

[0004] The invisible optical cable structure described in this utility model includes optical fibers and a sheath made of a light-transmitting material; two or more optical fibers are arranged side by side inside the sheath, and the outer wall of the sheath is provided with several tear holes that can guide the sheath to be torn open. Each tear hole is positioned opposite to two adjacent optical fibers. The sheath is also provided with reinforcing ribs inside, which are arranged around the outside of all optical fibers or different reinforcing ribs are arranged around the outside of different optical fibers.

[0005] The invisible optical fiber cable structure described in this utility model embeds the optical fiber within a sheath, which is then protected by the outer jacket. The sheath is made of a light-transmitting material, or even a transparent material, to achieve an "invisible" effect, minimizing its impact on interior decoration. The sheath can accommodate one or more optical fibers, forming single-core, two-core, three-core, or even four-core or higher transmission cables to meet various transmission requirements. When single-core or two-core cables are needed, tearing openings in the sheath can be used to separate the multi-core cable into single or two cores, adapting to indoor environmental conditions and reducing operating costs. Furthermore, the sheath contains reinforced ribs of higher strength, which surround the optical fiber, improving the cable's tensile, compressive, and bending resistance, and better protecting the inner optical fiber for safer and more stable operation.

[0006] Preferably, there is an even number of optical fibers, and the shape of the sheath is symmetrically arranged about the center line between the two middle optical fibers.

[0007] Preferably, four optical fibers are arranged side by side inside the sheath, with the tear opening positioned opposite to the two middle optical fibers.

[0008] Preferably, the sheath is made of a transparent material.

[0009] Preferably, a tear is provided between each adjacent optical fiber on the sheath.

[0010] Preferably, the tear is located in the middle of one side of the sheath, and the other side of the sheath has an adhesive self-adhesive coating.

[0011] Preferably, the tear is V-shaped, with the top opening of the V-shape facing outwards.

[0012] Preferably, the sheath contains one or more reinforcing ribs, each of which is located outside a different optical fiber.

[0013] Preferably, the reinforcing ribs are arranged on the outside of the optical fiber along the spiral direction.

[0014] Preferably, the reinforcing ribs are arranged in a ring, and multiple reinforcing ribs are spaced apart along the direction of the optical fiber.

[0015] By implementing the aforementioned concealed fiber optic cable structure, the concealment effect of the cable can be effectively guaranteed, further improving the cable's resistance to pressure and bending, and meeting different usage needs. Attached Figure Description

Therefore, features defined with "first" or "second" may explicitly or implicitly include at least one of those features. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them.

[0024] This utility model proposes an invisible fiber optic cable structure.

[0025] Example 1, as Figure 1 , 2 As shown.

[0026] The invisible fiber optic cable structure of this embodiment includes an optical fiber 1 and a sheath 2 made of a light-transmitting material. The four optical fibers are arranged side by side inside the sheath. The outer wall of the sheath is provided with a tear 3 that can guide the sheath to be torn open. The tear 3 is positioned opposite to the two middle optical fibers. The sheath is also provided with reinforcing ribs 4 inside the sheath. The reinforcing ribs are arranged around the outside of all the optical fibers.

[0027] The aforementioned invisible fiber optic cable structure embeds four optical fibers within a sheath, which is then protected by a transparent outer jacket to create an "invisible" effect, minimizing its impact on interior decoration. The sheath can accommodate one or more optical fibers, forming single-core, two-core, three-core, or even four-core or higher transmission cables to meet diverse transmission requirements. Furthermore, when single-core or two-core cables are needed, tearing openings in the sheath allow the multi-core cable to be split into single or two cores. Figure 1 The four-core cable shown is torn into two two-core cables to meet the needs of the indoor environment and reduce the cost of use. In addition, a stronger reinforcing rib is embedded in the sheath. The reinforcing rib surrounds the optical fiber, which can improve the cable's tensile, compressive and bending resistance, and better protect the inner optical fiber, so that it can work more safely and stably.

[0028] The aforementioned invisible fiber optic cable structure has an even number of optical fibers 1. The shape of the sheath 2 is symmetrical about the centerline between the two central optical fibers. For example, if the sheath is set as a semi-butterfly shape and the tear opening 3 is set in the middle of one side of the sheath, when it is necessary to tear the cable into two, the two cables can form a consistent shape, thus ensuring the consistency and aesthetics of the appearance. The tear opening 3 is V-shaped, with the top opening of the V-shape facing outwards and the pointed end located inside the sheath, which makes it easier to strip a single cable into multiple cables. It can also serve as a directional guide, allowing outdoor tearing in a specific direction, greatly reducing the chance of damage to the optical cable. In addition, the other side of the sheath 2 is provided with an adhesive self-adhesive coating 5. This is because existing FTTR cables need to be installed in conduits or fixed with additional tools, which not only affects construction efficiency but also damages interior decoration. The self-adhesive coating allows the cable to be easily fixed to the wall or equipment, thereby improving construction efficiency, reducing adverse effects on interior decoration, and ensuring the "invisible" effect of the cable.

[0029] The aforementioned invisible optical cable structure uses steel wire as the reinforcing rib 4, but it can also be made of carbon fiber, PPTA fiber, PPS fiber, SiC fiber, or other high-strength fiber materials. The reinforcing rib 4 is arranged on the outside of the optical fiber along the spiral direction, forming a spring-like structure. On the one hand, the gaps between the "springs" ensure the invisible visual effect, and on the other hand, it can provide all-round winding protection for the optical fiber, forming a protective skeleton. This increases the support points per unit length, allowing the optical cable to disperse stress when under force, further enhancing the optical cable's resistance to pressure and bending. Under conditions such as bending, compression, or even right-angle laying, it avoids damage to the optical cable core and ensures signal transmission quality.

[0030] Example 2, as Figure 3 As shown.

[0031] In this embodiment of the invisible optical cable structure, each adjacent optical fiber 1 on the sheath 2 is provided with a corresponding tear 3; as shown in this utility model, four optical fibers are provided inside the sheath, and three tear 3 are provided, so that the cable can be stripped into four single-core cables.

[0032] Example 3, as Figure 4 As shown.

[0033] In this embodiment, the invisible optical cable structure has two or more reinforcing ribs 4 inside the sheath 2, and each reinforcing rib is set outside a different optical fiber 1. This allows each cable to retain a structurally complete spring-shaped reinforcing rib when it is stripped into multiple strands, so as to ensure the structural strength and pressure and bending resistance of each cable.

[0034] Example 4, as Figure 5 As shown.

[0035] In this embodiment, the invisible fiber optic cable structure has a ring-shaped reinforcing rib 4, and multiple reinforcing ribs are spaced apart along the direction of the fiber optic cable 1. The gaps ensure a transparent visual effect and also facilitate cutting to the required length.

All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
