Description

Technical Field

[0001] This utility model relates to the field of optical cable technology, specifically a central loose tube type outdoor optical cable. Background Technology

[0002] With the rapid development of communication technology, optical fiber communication has become the main method of modern information transmission due to its advantages such as high bandwidth, low loss, and strong anti-interference capability. Outdoor optical cables, as an important component of optical fiber communication networks, need to maintain stable transmission performance under complex environmental conditions. Centrally coiled optical cables, due to their compact structure, high tensile strength, and good waterproof performance, are widely used in outdoor communication projects.

[0003] However, during the laying or use of optical cables, the outer sheath is often worn due to friction with the ground, pipes or other objects. Long-term wear may reduce the protective performance of the optical cable and even lead to the intrusion of moisture or impurities, affecting the transmission performance of the optical fiber. Therefore, a central loose tube type outdoor optical cable is proposed to overcome the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a centrally bundled tube type outdoor optical cable. The wear-resistant texture on the outside of the wear-resistant layer adopts a fine diamond-shaped mesh structure to increase surface friction resistance and reduce external force wear. At the same time, the wear-resistant protrusions are arranged in a spiral array to further disperse friction stress and extend the service life of the optical cable during dragging, laying or moving. This solves the problem that the outer sheath is often worn due to friction with the ground, pipes or other objects. Long-term wear may reduce the protective performance of the optical cable and even allow moisture or impurities to enter, affecting the transmission performance of the optical fiber.

[0005] This utility model is achieved through the following technical solution:

[0006] This utility model is a central loose tube type outdoor optical cable, including an optical cable, four reinforcing ribs on the outside of the optical cable, a connecting sleeve between the four reinforcing ribs, an abrasion-resistant layer on the outside of the reinforcing ribs and the connecting sleeve, abrasion-resistant texture on the outside of the abrasion-resistant layer, bending grooves evenly opened on the abrasion-resistant layer, and abrasion-resistant protrusions evenly distributed on the outside of the abrasion-resistant layer.

[0007] Furthermore, the optical cable includes four optical fibers, a central reinforcing member in the middle of the four optical fibers, a filling layer on the outside of the four optical fibers, a loose tube on the outside of the filling layer, a waterproof layer on the outside of the loose tube, and a buffer layer on the outside of the waterproof layer.

[0008] Furthermore, reinforcing ribs and connecting sleeves are provided on the outside of the buffer layer.

[0009] Furthermore, the wear-resistant texture is a fine diamond-shaped mesh structure.

[0010] Furthermore, the bending groove has a V-shaped structure.

[0011] Furthermore, the wear-resistant bumps are configured in a spiral array.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model uses a fine diamond-shaped mesh structure for the wear-resistant texture on the outside of the wear-resistant layer to increase surface friction resistance and reduce external wear. At the same time, the wear-resistant protrusions are arranged in a spiral array to further disperse frictional stress and extend the service life of the optical cable during dragging, laying or moving. It solves the problem that the outer sheath is often worn due to friction with the ground, pipes or other objects. Long-term wear may reduce the protective performance of the optical cable and even lead to the intrusion of moisture or impurities, affecting the transmission performance of the optical fiber.

[0014] 2. This utility model uses bending grooves evenly distributed on the wear-resistant layer to make the stress distribution of the optical cable more uniform when it is bent, preventing local stress concentration from causing damage to the optical fiber. With the synergistic effect of the buffer layer and the waterproof layer, it absorbs external impacts and protects the internal optical fiber to maintain stable transmission in dynamic bending environment.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3This utility model provides a technical solution: a centrally bundled tube type outdoor optical cable, including an optical cable 1. The optical cable 1 has four reinforcing ribs 2 on its exterior. The reinforcing ribs 2 are typically made of aramid fiber (Kevlar), steel wire, or GFRP (glass fiber reinforced plastic). Connecting sleeves 3 are provided between the four reinforcing ribs 2. The connecting sleeves 3 are made of high-density polyethylene (HDPE) or nylon and are used to fix the reinforcing ribs 2. The reinforcing ribs 2 provide tensile and compressive support, and the connecting sleeves 3 maintain structural stability and prevent displacement of the reinforcing ribs 2. An abrasion-resistant layer 4 is provided on the exterior of the reinforcing ribs 2 and the connecting sleeves 3. The abrasion-resistant layer 4 is made of high-density polyethylene (HDPE) or polyurethane (PU), which has high abrasion resistance, protects the optical cable 1 from external friction and wear, and extends its service life. The wear-resistant layer 4 has wear-resistant textures 401 on its exterior. The wear-resistant textures 401 are integrally formed with the wear-resistant layer 4 and are usually made of HDPE or PU. The wear-resistant textures 401 are a fine diamond-shaped mesh structure. The diamond mesh structure enhances the surface hardness and reduces external scratch damage. The wear-resistant layer 4 has evenly distributed bending grooves 402. The bending grooves 402 are V-shaped structures and are made of the same material as the wear-resistant layer 4. They are made of V-shaped cutting technology to provide flexible bending points and prevent the sheath of the optical cable 1 from cracking when bent. The wear-resistant layer 4 has evenly distributed wear-resistant bumps 403 on its exterior. The wear-resistant bumps 403 are made of wear-resistant rubber or reinforced plastic such as polyamide. The wear-resistant bumps 403 are set in a spiral array. The spiral array design disperses external friction stress and reduces local wear.

[0022] Optical cable 1 includes four optical fibers 101, which are typically made of quartz glass fiber (single-mode / multimode) and coated with an acrylic resin protective layer. A central reinforcing member 102 is provided between the four optical fibers 101. The central reinforcing member 102 is generally made of high-strength non-metallic material (such as FRP, glass fiber reinforced plastic) or metal (such as steel wire). A filling layer 103 is provided outside the four optical fibers 101. The filling layer 103 is made of water-blocking grease or water-absorbing and expanding material (such as polyacrylate). A loose tube 104 is provided outside the filling layer 103. The loose tube 104 is made of PBT (polybutylene terephthalate) or PP (polypropylene) and is temperature and pressure resistant. A waterproof layer 105 is provided outside the loose tube 104. The waterproof layer 105 is made of aluminum-plastic composite tape (APL) or water-blocking tape. A buffer layer 106 is provided outside the waterproof layer 105. The buffer layer 106 is made of foamed polyethylene (PE) or elastic polyurethane (PU) to provide cushioning protection. Reinforcing ribs 2 and connecting sleeves 3 are provided outside the buffer layer 106.

[0023] Optical fiber 101 is responsible for optical signal transmission, central reinforcement 102 provides tensile strength, filling layer 103 prevents water vapor penetration, loose tube 104 protects optical fiber 101 from stress, waterproof layer 105 and buffer layer 106 enhance environmental adaptability, ensure low signal loss transmission, improve tensile, compressive and waterproof performance, and adapt to complex outdoor environments.
