[Previous technology] Optical fiber cables are gradually more widely used for communication transmission because they are less affected by electromagnetic noise than traditional communication cables and have a large average transmission capacity of a single core, especially in the current Internet. The increase in the popularity of popular and multimedia applications has resulted in an increase in demand for broadband, broadening the scope of application of fiber optic cables, connectors and jumpers in fiber optic networks. = Compressed, f-curved deformation mechanical strength or impurities are poor. The light-line covered by the metal tube is to respond to the mechanical strength such as tensile strength, lateral pressure resistance, and bending resistance described in Shang Shangyue.

The previous case has the disadvantages described below. First, referring to the schematic diagram of the relationship between the optical fiber core wire (c) of the previous case and the flexible pipe 所示 shown in Figure 1, it can be seen that each pitch member of the flexible pipe (T) is composed of a large diameter part ㈤ and a small diameter part ⑽.

It has excellent tensile strength, 'compressive strength', resistance to bending or lateral pressure, cut resistance, and low cost. , Can be refined and can provide long-distance signal transmission cables. The optical fiber cable and the optical fiber connector are combined to form a high-quality optical fiber patchcord. The present invention still provides an optical fiber cable device based on the foregoing optical fiber cable, including: the optical fiber, the cable, and the optical fiber connector are combined to form a high-quality optical fiber jumper. The desirable substance of the present invention can be made clear from the following description in conjunction with the accompanying drawings. [Embodiment] Referring to the drawings, the optical fiber cable U) of the present invention includes a fiber core (11), and a core reinforcing material (12) coaxially covers the fiber core (H) around an axis (X). A continuous coiled metal tube (13) coaxially surrounds the core wire reinforcing material (12), and a flexible anti-cutting protective layer (14) coaxially covers the metal tube ( 13), and an insulator coating layer (15) is coaxially sheathed on the outer layer of the cut-resistant protective layer (14), and the optical fiber cable is formed coaxially or concentrically. The core reinforcing material (12) may be a core reinforcing fiber, for example, a fiber or a fiber bundle selected from aromatic polyamide fibers such as the brand name kevlar produced by DuPont. Of course, other suitable materials can also be selected. If the optical fiber cable is too thin and there is no risk of friction or damage between the continuous spiral metal pipe (13) and the axial core wire (11), the core wire reinforcing material (12) may be exempted; of course, the core wire (11 ) Can be directly coated with a polymer coating, if so, the kevlar reinforcing material can be omitted. This is a modified application example of the present invention. The "spirit" of the present invention is the continuously coiled metal tube (13), which can be made into a coiled spring with the principle and method of stainless steel or other metals with good mechanical strength. Coiled coil (coiled winding, 131), phase 200538774 There is a gap (132) between adjacent coils (131), such as coil springs. As a result of this invention-innovative invention ', a continuous spiral metal tube (13) is used instead of the conventional metal tube used for fiber optic mirror wires, which are made of most "pitch members" snapped and connected to each other (as shown in Figure 丨). ) 'S flexible pipe (D), which gives the high-quality mechanical characteristics and related advantages of the present invention (to be described later). The continuous spiral metal pipe (13) of the present invention imparts tensile strength, compressive strength, and flexibility to the composed optical fiber cable (1). The buckle, connected large diameter portion (T1) and small diameter portion (T2) occupy a certain depth, so the diameter of the present invention can be greatly reduced. This is the so-called "thinnable" optical fiber cable The reason for the wire is that the diameter is small, the weight is reduced, the cost is reduced, and it can be applied to the manufacture and construction and installation of long-distance optical fiber wires, which is superior to the former case. In order to make the present invention perfect, avoid external force such as a sharp knife to cut along the gap (132) between two spiral coils (131) of the spiral metal pipe (13) to cut the optical fiber cable (1), In the present invention, the flexible cut-resistant protective layer (fat "this") is coated on top of the metal i (13). Overcome cutting with a knife and have anti-cutting and lateral pressure resistance. Of course, 'The flexible cut-resistant protective layer (14) can be used in addition to the aforementioned stainless steel woven mesh. The invention is not limited to it. Finally, the outermost layer is covered by the cut-resistant protective layer (14) with an insulator coating layer (15). Since the metal pipe (13) and the stainless steel protective layer (14) are selected in the present invention If accidental exposure may result in erroneous transmission of electrical energy and damage to the entire signal transmission system, it must be covered with an electrical insulator coating such as a polymer insulator such as polyvinyl chloride (PVC), so as to constitute the optical fiber cable of the present invention ⑴. The optical fiber cable (1) of the present invention can be manufactured according to a known optical fiber cable manufacturing method. It is made by machinery and plastic processing machinery and equipment. As shown in Figure 2, the fiber optic cable (1) of the present invention can be used to form a patchcord and it is widely used in optical fiber by mating the connector (2). In the transmission system, 200538774 Zheng Yuanzheng's fiber optic line (1) penetrates into the strain relief tail pipe (2i, strain_reiief b〇〇t), and then passes through the clamp tube, the metal tube of the fiber optic cable, and the clamp tube ( 22) The mouth of the tube is flush, so that the kevlar core wire reinforcing material (12) and the stainless steel braided protective layer (14) of the optical fiber cable ⑴ are wrapped or sleeved on the back of a support sleeve ⑼, the support sleeve (23) It is crimped with kevlar core reinforcing material (12), non-recorded steel braided mesh protection layer and Yanguan (22) net element, and is fastened. The front end of the support sleeve (23) fits into a solid head cover (25). Hole, the supporting sleeve (23) and the fixed head 2 (25) inside the elastic elastic Gona-Tao ceramic ferrule (24, no ㈣ ^), the ferrule (24) is actually borrowed by a small spring (24, W-shaped support is located inside the support sleeve (23) and the fixed head cover (25). Pottery: it is the rear end of the ferrule, connected to the optical fiber and the core wire of the cable (1)). The fixed head cover (25) is Weiren —_ Among the hats, The front end of the Boxman ferrule (24) protrudes through the center of the fixed headgear (25) in the light closing cap (26) to handle or connect another optical fiber (not shown). ) Finally, it is overlapped with the tail pipe (21), and the other components of the aforementioned connector (2) are packaged. During storage and transportation, and not yet in use, the front end of the wire closure cap (26) can be stuffed with a piece of earth (27) ) Those who think it is dust-proof and keep it in a clean and standby state. The characteristics of the present invention are better than those of the conventional Nissho Nippon Steel Dissolving Company. The data are shown in the following table: 15kgf compressive strength 350kgf / mm 25〇kgf / mm bending radius 30mm 40mm inner diameter 1.0mm 1.8mm test according to JIS-C6821 JIS-C5961 According to the above table, it can be seen that the mechanical strength of the present invention is better than that of Japanese commercial products, and the meat is thin. The bending radius is also smaller, showing the excellent characteristics of the present invention, but the inner diameter of the present invention is better than 200538774. The seam material for the optical fiber connection n (2) is a well-known technology. It can be applied by skilled artisans according to actual needs. The present invention is not limited by the spirit and scope of the present invention. The present invention can be used for multiple lights: the application of the present invention line; or-a fiber through the connection H and then split into multiple lights to limit the green · u "... a ▲, a security line through the connector sink Those connected to a fiber-optic fiber-optic cable have many changes.
