Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides an optical fiber cable with a long service life, which solves the problem that most optical fibers are placed on the ground before being laid, and are easily bitten by animals and crushed by vehicles, etc. Exposure to the environment for a long time after laying causes the outer protection of the cable to break, and the current optical fiber is constantly pulled during laying. If the outer protection slips, the internal optical fiber is prone to breakage due to force , does not have a long-term use, and does not have a good protection for the internal optical fiber, resulting in a high investment in the popularity of the optical fiber and the maintenance cost after laying

Embodiment Construction

[0029] The technical solution of the present patent will be described in further detail below in conjunction with specific embodiments.

[0030] like Figure 1-7As shown, the present invention provides a technical solution: an optical fiber cable with a long service life, comprising a support frame 1, the support frame 1 is made of tough steel plate, and the difference between the diameter of the inner wall of the limiting groove 19 and the surface diameter of the deformation layer 11 is three millimeters. By setting the bracket 1, the bracket 1 can maintain stable protection for the optical fiber 15 during use, and can maintain a stable supporting effect at the same time. It has good toughness and can be reset in time after the end of the force. By setting the limit groove 19, the limit groove 19 can protect the optical fiber 15 well, and at the same time, it can spread the pressure evenly and make the pressure change. The surface of the support frame 1 is provided with a co...

Abstract

The invention discloses an optical fiber cable with high service life, belonging to the technical field of optical fiber cables. The surface of the elastic shock absorption layer is provided with a water-sealing layer, and the surface of the water-sealing layer is provided with a tensile layer. The optical fiber cable with high service life is provided with a deformation layer and a barrier layer. When the surface of the deformation layer is subjected to a uniform extrusion force from the limiting groove, the surface of the optical fiber cable begins to be flattened gradually. It can play a good supporting effect, so that it can maintain the stable protection of the internal optical fiber, and the deformation layer is made of fluororesin material with smooth surface, and then the inner wall of the limit groove is reduced to a certain threshold, so that the internal deformation layer can be Under the action of the squeezing force, it slips out, and at the same time, after being buffered by the filling layer, several shields on the outside of the squeeze are deformed, so that it can stably protect the optical fiber.

Description

technical field [0001] The invention belongs to the technical field of optical fibers and cables, in particular to an optical fiber cable with high service life. Background technique [0002] Fiber optic cable is a communication cable consisting of two or more glass or plastic fiber optic cores within a protective cladding covered by a plastic PVC outer sleeve. Signal transmission along internal fibers typically uses infrared, a dielectric waveguide that transmits light waves. Optical fiber is a kind of fiber composed of two layers of transparent media in concentric circles. The most widely used dielectric material is quartz glass (SiO2). The inner medium, called the core, has a higher refractive index than the outer medium, called the cladding. The refractive index of the core or cladding is adjusted by doping germanium, phosphorus, fluorine, boron and other impurities in the silica glass. The transmission wavelength of communication optical fibers is mainly near-infrar...
