Abstract
The utility model relates to a layer stranded miniature optical cable with high density, which is suitable for air blast laying. The utility model comprises an outer sheath and an optical fiber, and is characterized in that the inner part of the outer sheath is coated with four stranded sheath loosening tubes; the inner parts of the sheath loosening tubes are laid with optical fibers, the middle of the four sheath loosening tubes is stranded with a central reinforcing element. The outside of the outer sheath can also be coated with one layer of solid lubricating layer so as to enhance the lubricating property of the miniature optical cable at the time of air blast laying. The utility model has the advantages that the utility model is suitable for carrying out air blast laying in a miniature plastic conduit, construction speed is high, and the laying cost of the optical cable can be reduced; the optical cable has large optical fiber density and small diameter and can enter a silicon core miniature tube with smaller tube diameter, so that the availability ratio of a communication pipeline can be increased, and investment cost for establishing a network can be lowered; compared with a central tube-type structure, optical fibers are easy to be diverged and the utility model is convenient for connection and construction.
Description
Technical field
The utility model relates to a kind of Layer Cutter Mini Cable with high density of optic fibre that is suitable for air-blown installation.
Background technology
Along with the fast development of the communication technology, micro optical cable has been widely used in the micro optical cable network of air-blown installation.Existing micro optical cable is the central tubular structure, is about to optical fiber and is sleeved in a metal tube or the plastic tube, coats oversheath again and constitute outside metal tube or plastic tube.The density of optic fibre of this central tubular micro optical cable is high not enough, makes that the making of optical cable is relative with laid down cost higher, and the flexibility of optical cable and flexibility are relatively poor, and the difference performance is also desirable not to the utmost.
Summary of the invention
Technical problem to be solved in the utility model is the deficiency that exists at prior art and a kind of Layer Cutter Mini Cable with high density of optic fibre is provided, and not only the pipeline occupation rate is low for it, and making and laid down cost are low, the difference when being convenient to be applied to the family.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include oversheath and optical fiber, its difference is to be coated with four mutually stranded loose sleeve pipes in oversheath, be laid with optical fiber, the stranded central reinforce member in the centre of four loose sleeve pipes in the pine sleeve pipe.
Press such scheme, the diameter of described loose sleeve pipe is 1.6～2.1mm; Every loose sleeve pipe includes 2～12 optical fiber, and described optical fiber can be the fibre ribbon of single beam one fine or arranged side by side; The mutually stranded pitch of each loose sleeve pipe is 180～250mm.
Press such scheme, can cover one deck solid lubricant layer, to strengthen the lubricity of micro optical cable when the air-blown installation in the oversheath outsourcing.
The beneficial effects of the utility model are: 1, be suitable for carrying out air-blown installation in the micro plastic pipeline, speed of application is fast, has reduced the laid down cost of optical cable; 2, the density of optic fibre of optical cable is big, and diameter is little, can enter in the smaller silicon core miniature tube of caliber, improves the utilization factor of communication pipe, and the networking cost of investment is reduced; 3, compare with the central tubular structure, the easy difference of optical fiber can be convenient to continue and construct.
Description of drawings
Fig. 1 is the radial structure sectional view of an embodiment of the utility model.
Fig. 2 is the radial structure sectional view of another embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
First embodiment as shown in Figure 1, include four loose sleeve pipes 2, be laid with the fine cream 5 of optical fiber 1 and filling in the pine sleeve pipe, the diameter of pine sleeve pipe can be 1.6～1.8mm, fine 6 of interior dress single beam, perhaps the diameter of loose sleeve pipe is 1.9～2.1mm, fine 12 of interior dress single beam, each loose sleeve pipe is that SZ strand is mutually stranded, and twisting pitch is 180-250mm, the varying in color of four loose sleeve pipes, so that the identification and the differentiation of each loose sleeve pipe during difference, the middle part of cable core is provided with central reinforce member 6, and the loose sleeve pipe outsourcing after stranded is tied with pricks yarn 7, the outer coating outer jacket 3 of cable core, oversheath can be made with high density polyethylene (HDPE) material, in addition, can install out hawser 4 in the cable core, but filling cable cream 8 also.
Second embodiment as shown in Figure 2, the main difference part of it and a last embodiment is to cover one deck solid lubricant layer 9 in the oversheath outsourcing, described solid lubricant layer is the silicone plasties layer, thickness is 0.2～0.5mm, in addition, on solid lubricant layer, vertical dimpled grain can be set, further strengthen it in ducted greasy property.
