Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-layer bundled fiber optic tube optical cable technology, specifically a multi-layer bundled fiber optic tube optical cable. Background Technology
[0002] Optical cables are manufactured to meet optical, mechanical, or environmental performance specifications. They are communication cable assemblies that use one or more optical fibers encased in a protective sheath as the transmission medium and can be used individually or in groups. They are also one of the most common and widely used infrastructure items.
[0003] In the prior art, such as the application with application number CN117031653A, the subject is: "A multi-core optical cable comprising: a sheath layer, core wires, and a core sleeve; the core wires are provided in at least three strands, tangentially distributed around the axis of the optical cable; the core wires are bundled together by the core sleeve, forming a clustered central composite tube under the coverage of the core sleeve, the central composite tube being located at the axis of the sheath layer; the core wire body is hollow wire or hollow tube, containing optical fiber, thick reinforcing fiber, and hollow quartz wire. This invention, through improvements to the internal structure, increases the utilization rate of the internal space of the optical cable. While ensuring the multi-core characteristics of the multi-core optical cable, it significantly improves the mechanical properties of the optical cable with a small amount of alternative wire, giving it good compressive and impact resistance."
[0004] However, the aforementioned patents cannot effectively protect the internal optical fiber if the sheath layer is damaged during use, and also have a short service life. In addition, if they are attacked by external rodents or insects, a single sheath layer cannot effectively protect the safety of the optical fiber. Utility Model Content
[0005] The purpose of this invention is to provide a multi-layer bundled fiber optic cable to solve the problems in the prior art.
[0006] The objective of this utility model can be achieved through the following technical solutions:
[0007] A multi-layer bundled optical fiber tube cable includes an outer protective layer, an abrasion-resistant layer fixedly connected to the inner wall of the outer protective layer, a water-blocking layer fixedly connected to the inner wall of the abrasion-resistant layer, a plurality of reinforcing steel wires arranged on the opposite side of the water-blocking layer and the abrasion-resistant layer, an inner protective layer fixedly connected to the inner wall of the water-blocking layer, an optical fiber grease filled inside the inner protective layer, an optical fiber protective sleeve arranged inside the optical fiber grease, and an optical fiber body fixedly connected inside the optical fiber protective sleeve, with non-metallic reinforcing wires arranged on the opposite side of the optical fiber grease away from the optical fiber protective sleeve.
[0008] Preferably, the outer protective layer is made of nitrile rubber, and the wear-resistant layer is made of nylon fiber.
[0009] Preferably, the water-blocking layer is made of water-blocking yarn and water-blocking tape, and the reinforcing steel wire is located on the opposite side of the water-blocking yarn and the wear-resistant layer.
[0010] Preferably, the inner sheath is made of aramid fiber and is located on the opposite side of the optical fiber paste and the water-blocking layer.
[0011] Preferably, the optical fiber protective sleeve is made of glass fiber, and the non-metallic reinforcing wire is made of polytetrafluoroethylene.
[0012] Preferably, multiple fiber optic protective sleeves are provided, and the fiber optic protective sleeves are evenly distributed inside the fiber optic paste.
[0013] The beneficial effects of this utility model are:
[0014] 1. The outer protective layer made of nitrile rubber in this utility model can effectively reduce wear on optical cables when used in outdoor environments and prevent animals from tearing them during use. In addition, the wear-resistant inner layer made of nylon fiber can prevent the optical cable from breaking due to friction with the corner of the wall during use, thus improving the service life of the cable.
[0015] 2. This utility model uses reinforced steel wire to protect the internal water-blocking layer from wear after the wear-resistant layer and outer protective layer are damaged. It also helps personnel to bend and shape the optical cable in special environments. At the same time, the internal water-blocking layer can effectively prevent the internal cable from being damaged by rainwater after the outer protective layer and wear-resistant layer are damaged.
