Abstract
The utility model relates to a central pipe ADSS optical cable including an over sheath and a central sleeve pipe which is coated by the over sheath, and fiber units are arranged in the central sleeve pipe. The optical cable is characterized in that, longitudinal grooves are disposed in the outer surface of the central sleeve pipe in the circumferential direction and a non-metal reinforcing member is coated between the central sleeve pipe and the over sheath. The beneficial effects of the central pipe ADSS optical cable reside in that: (1) the optical cable has simple structure, easy preparing method, small external diameter, light weight, good flexibility, and excellent tensile property, and the optical cable is convenient to use in construction; (2) the central sleeve pipe with the grooves, the non-metal reinforcing member and the over sheath form a closely integrated structure, stress condition of the optical cable can be improved, a retraction problem of general sleeve pipes is overcome, tensile strength of the optical cable is further strengthened, and the optical cable can be applied to complicated construction and using environments, and the central sleeve pipe can facilitate pipe penetration and air-blowing laying after the optical cable is stripped; and (3) the optical cable can be applicable to wide use in various complex conditions of FTTX.
Description
Technical field
The utility model relates to a kind of central tubular ADSS optical cable, belongs to the communications optical cable technical field.
Background technology
Along with the FTTH fast development, optical cable is widely used in the optical-fiber network.Because environment for use and the situation of optical cable are different, different requirements has been proposed also for the structure of optical cable.Existing ADSS(all dielectric self-supporting) optical cable mostly is the layer-twisted type cable core structure greatly, and optic cable diameter is big, Heavy Weight, and this has strengthened construction intensity, has improved construction cost, has also prolonged the construction period.
Summary of the invention
Technical problem to be solved in the utility model is to propose a kind of central tubular ADSS optical cable at the deficiency of above-mentioned prior art existence, and this optical cable not only external diameter is little, and from heavy and light, flexibility is good, and pull resistance is strong, and construction is used more convenient.
The utility model is that the technical scheme that the problem of the above-mentioned proposition of solution adopts is: include oversheath and be coated in the oversheath center sleeve, be laid with fiber unit in the center sleeve, it is characterized in that described center sleeve outside surface along circumferentially being provided with longitudinal groove, is coated with non-metal reinforcement member between center sleeve and oversheath.
Press such scheme, the V-shaped or U-shaped in longitudinal groove cross section that described center sleeve outside surface circumferentially arranges.
Press such scheme, the longitudinal groove that described center sleeve outside surface circumferentially arranges is 12 ~ 30, and the longitudinal groove breadth extreme is 0.2mm ~ 0.5mm, and the radial depth of longitudinal groove is 0.2mm ~ 0.5mm.
Press such scheme, described fiber unit is optical fiber, fibre ribbon or fibre bundle.
Press such scheme, described center sleeve is filled with water-blocking component, and described water-blocking component is hydrogel, water blocking yarn, water-proofing powder or waterproofing rope, or is greasy for preventing water.
Press such scheme, described non-metal reinforcement member is full medium tensile elements such as aramid yarn, glass fiber yarn, FRP band, carbon fiber.
Press such scheme, described oversheath is made by the macromolecular material of anti-UV.
Press such scheme, in oversheath, be provided with out hawser.
The beneficial effects of the utility model are: 1, adopt central tubular all dielectric self-supporting structure, one-piece construction is simple, manufactures easyly, and not only external diameter is little, and from heavy and light, flexibility is good, and possesses good tensile property, construction and easy to use; 2, the center sleeve outside surface is along circumferentially being provided with longitudinal groove, split thimble coats non-metal reinforcement member, make fluting center sleeve, non-metal reinforcement member and oversheath form an integral body of combining closely, can improve the force-bearing situation of optical cable, solve the back contracting problem of ordinary casing, and the tensile strength of optical cable is further strengthened, can bear complicated construction environment and environment for use; In addition, the center sleeve behind the optical cable baring can be convenient to poling and air-blown installation; 3, full dielectric structure is not subjected to the interference of various electromagnetic fields and influences, and self-bearing type is built on stilts to be laid, and can utilize to have electric power tower bar facility now, also can make somebody a mere figurehead by the self-bearing type that carries out between building, is widely used in the various complexity of FTTX Fiber to the home to lay.
Description of drawings
Fig. 1 is the radial section figure of an embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
As shown in Figure 1, it is a four-core dry type central tubular ADSS optical cable, comprise that outside surface arranges the center sleeve 3 of V-arrangement longitudinal groove vertically, the longitudinal groove that described center sleeve outside surface circumferentially arranges is 28, the longitudinal groove breadth extreme is 0.2mm, and the radial depth of longitudinal groove is 0.2mm; Contain four optical fiber 1 and a water blocking yarn 2 at center sleeve, form the dry type sleeve structure; The circumferential uniform non-metal reinforcement member 4 in the center sleeve outer, described non-metal reinforcement member is aramid yarn or glass fiber yarn, the outer oversheath 6 that closely coats of non-metal reinforcement member, described oversheath is made by the macromolecular material of anti-UV, in oversheath, be provided with out hawser 5, can be convenient to the stripping of opening of cable outer sheath, conveniently register one's residence and lay and use.
