Abstract
The utility model discloses a novel small-diameter overhead optical cable, which comprises a sheath loosening tube, a filling rope, a reinforcing element, a water resisting rope, a tearing rope and a protective layer and a sheath wrapped at the outside, wherein the inside of the sheath loosening tube is provided with optical fibers and fiber paste; the reinforcing element is composed of high-strength glass reinforcement fibers, and is positioned at the rim adjacent to the protective layer; the sheath loosening tube is in parallel with the reinforcing element. The utility model has the characteristics of small diameter, light weight, simple structure, etc. The utility model can solve the problem that city communication line telegraph poles bear excess cable and optical cable load, and as well as can satisfy the increased demand to optical cables with small number of cores in the construction of leading optical fibers into a doom, and simultaneously can be used for outdoor feeder lines and wiring for an access network. The utility model can also be used for light leading-in wires, has the advantages of low total cost of the optical cable and convenient use, and provides a fire-new solution for each telecommunication operator.
Description
Technical field
The utility model relates to a kind of novel minor diameter aerial optical cable.
Background technology
In the prior art, traditional loose sleeve layer strand type cable configuration and central beam tube type cable configuration are respectively as shown in Figure 1 and Figure 2, the restriction that reduces to be subjected to loose casing size CS and central reinforce member of layer-twisted type loosely shielded optical cable diameter and weight, though and the central tubular loosely shielded optical cable has little, the lightweight characteristics of diameter, it is not easy to the branch fibre in use.
Summary of the invention
The purpose of this utility model is: a kind of novel minor diameter aerial optical cable is provided, and it moves to the edge with central reinforce member by the center, reduces the space of cable core by loose sleeve pipe and central reinforce member configured in parallel, thereby reduces optic cable diameter and alleviate optical cable weight.
The technical solution of the utility model is: a kind of novel minor diameter aerial optical cable; establish loose sleeve pipe, gasket for packing, the reinforcement of optical fiber and fine cream, the protective seam and the sheath of outsourcing in comprising; described reinforcement is positioned at edge, loose sleeve pipe and the reinforcement configured in parallel near protective seam.
The further technical scheme of the utility model is: a kind of novel minor diameter aerial optical cable, establish loose sleeve pipe, gasket for packing, the reinforcement of optical fiber and fine cream, the protective seam and the sheath of outsourcing in comprising, described reinforcement is positioned at the edge near protective seam, loose sleeve pipe and reinforcement configured in parallel; Described reinforcement is the high strength glass fortifying fibre.
The more detailed technical scheme of the utility model is: a kind of novel minor diameter aerial optical cable, establish loose sleeve pipe, gasket for packing, the reinforcement of optical fiber and fine cream, the protective seam and the sheath of outsourcing in comprising, described reinforcement is positioned at the edge near protective seam, loose sleeve pipe and reinforcement configured in parallel; Described reinforcement is the high strength glass fortifying fibre; Be provided with waterproofing rope in the described protective seam and tear rope.
The utility model has the advantages that:
1. to make optical cable have an external diameter little, in light weight, simple in structure for the utility model unique design, the characteristics of good bending property.The traditional layer-twisted type loosely shielded optical cable diameter and the restriction that reduces to be subjected to loose casing size CS and central reinforce member of weight, though the central tubular loosely shielded optical cable has little, the lightweight characteristics of diameter, it is not easy to the branch fibre in use.And the design feature of this novel aerial optical cable is that central reinforce member is moved to the edge by the center, has reduced the space of cable core by loose sleeve pipe and central reinforce member configured in parallel, to reach the purpose that reduces optic cable diameter and weight reduction.
2. cable core of the present utility model does not need stranding stranded, and manufacturing step reduces to pine cover and 2 technology manufacturing steps of sheath by original pine cover, stranded and 3 technology manufacturing steps of sheath, both can reduce material usage, can enhance productivity greatly again.
3. the utility model adopts accurately advanced surplus long control technology to make the optical fiber in the sleeve pipe have rational surplus length, guarantees that optical cable has good temperature performance.
4, place high strength glass fortifying fibre reinforcement and waterproofing rope around the sleeve pipe of the present utility model in the space, not only guaranteed that optical cable has the tensile property of excellence but also the light unit radial is blocked water.
5, the utility model adopts the dry type cable core to be convenient to construction and use.
6, the built-in high strength of sheath of the present utility model is torn rope, makes cable be easy to out stripping, construct and continue.Oversheath adopts high-quality HDPE material to extrude, and the waterproof mildew-resistant has good resisting environmental stress and cracking ability.
Description of drawings
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is traditional loose sleeve layer strand type cable configuration synoptic diagram;
Fig. 2 is traditional central beam tube type cable configuration synoptic diagram;
Fig. 3 is a structural representation of the present utility model.
Wherein: 1 optical fiber; 2 fine cream; 3 loose sleeve pipes; 4 gasket for packings; 5 reinforcements; 6 protective seams; 7 sheaths; 8 waterproofing rope; 9 tear rope.
Embodiment
Embodiment: as shown in Figure 3; a kind of novel minor diameter aerial optical cable; establish in comprising optical fiber 1 and fine cream 2 loose sleeve pipe 3, gasket for packing 4, reinforcement 5, waterproofing rope 8, tear the rope 9; the protective seam 6 of outsourcing and sheath 7; described reinforcement 5 is made up of the high strength glass fortifying fibre; and be positioned at edge near protective seam 6, loose sleeve pipe 3 and reinforcement 5 configured in parallel.
The utility model is a kind of built on stilts novel optical cable that lays that is applicable to, adopts unique design, has characteristics such as diameter is little, in light weight, simple in structure.Both can solve the problem of bearing too much cable and optical cable load on the communication line pole, in can satisfying again that Fiber to the home and building little core is counted the demand that optical cable increases day by day, also can be used for simultaneously the outdoor feeder line and the distribution of Access Network, also can be used for the light inlead.This optical cable is totally with low cost, and is easy to use, for each telecom operators provides a kind of brand-new solution.
