Abstract
The utility model relates to a double-loose-bushing micro-optical cable which can be laid in an air blast way in a micro plastic pipeline, and in particular to a micro-optical cable with high optical fiber density, which comprises two loosen bushings, wherein optical fibers are arranged inside each loosen bushing, and an outer protection jacket is wrapped outside the loosen bushings, and is characterized in that the two loosen bushings are arranged in parallel from left to right, and a fiber strengthening plastic supporting element is installed at the upper side and the lower side inside the outer protection jacket. The double-loose-bushing micro-optical cable has the advantages as follows: 1. the loosen bushings are free from being twisted with each other, thereby reducing the cable assembly procedures in the production process, and improving the production efficiency; 2. compared with the layer-stranding micro-optical cable with two loosen bushings and two gaskets for packing, the material cost of the optical cable is reduce, and the double-loose-bushing micro-optical cable is a substitute for the layer-stranding micro-optical cable with two loosen bushings and two gaskets for packing; 3. compared with the central pipe-type structure, the optical fibers are easy to be branched, thereby being convenient for the connection and the construction; 4. the optical fiber density of the optical cable is large, and the outer diameter of the optical cable is small, and the weight is light, so that the double-loose-bushing micro-optical cable can be laid in an air blast way for a long distance.
Description
Technical field
The utility model relates to a kind of two loose sleeve pipe micro optical cable that can carry out air-blown installation at the micro plastic pipeline, is a kind of micro optical cable with high density of optic fibre.
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 has 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, make that the making of optical cable is relative with laid down cost higher, and the pliability of optical cable is relatively poor, and optical fiber difference performance is also desirable not to the utmost.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of full medium micro optical cable at the deficiency of above-mentioned prior art existence, and not only cost of manufacture is low for it, and is in light weight, and density of optic fibre is big.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include 2 loose sleeve pipes, be laid with optical fiber in the every loose sleeve pipe, the pine sleeve pipe coats oversheath outward, it is characterized in that tiling setting side by side about 2 loose sleeve pipes, both sides are installed on the fibre reinforced plastics supporting member up and down in oversheath.
Press such scheme, described 2 parallel placements of loose sleeve pipe, the diameter of loose sleeve pipe is 1.6～2.1mm, every loose sleeve pipe includes 2～12 optical fiber.
Press such scheme, both sides and 2 perpendicular directions of the loose sleeve pipe line of centres about described fibre reinforced plastics supporting member symmetry is installed in the oversheath.
The beneficial effects of the utility model are: 1, loose sleeve pipe is not stranded mutually, has reduced the stranding operation in the production run, has improved production efficiency; 2, compare with the Layer Cutter Mini Cable of 2 gasket for packings with 2 loose sleeve pipes are arranged, reduced the material cost of optical cable, become its substitute products; 3, compare with the central tubular structure, the easy difference of optical fiber can be convenient to continue and construct; 4, the density of optic fibre of optical cable is big, and cable outer diameter is little, in light weight, can big distance ground air-blown installation.
Description of drawings
Fig. 1 is the radial structure sectional view of an embodiment of the utility model.
Embodiment
Further specify embodiment of the present utility model below in conjunction with accompanying drawing.
Include parallel loose sleeve pipe 3 arranged side by side about 2, varying in color of 2 loose sleeve pipes, so that the identification and the differentiation of each loose sleeve pipe during difference, be laid with the fine cream 1 of optical fiber 2 and filling in the pine sleeve pipe, the diameter of loose sleeve pipe can be 1.6～2.1mm, 2～12 of interior dress single beam fibres, the pine sleeve pipe holds aramid fiber or water blocking yarn 5 outward, the outer oversheath 4 that coats, oversheath available polyethylene (PE) material is made, and constitutes the rounded full medium micro optical cable in cross section.Up and down the perpendicular direction symmetry of both sides and 2 loose sleeve pipe lines of centres is installed on fibre reinforced plastics supporting member 6 in oversheath.
Claims (4)
1, a kind of two loose sleeve pipe micro optical cable, include 2 loose sleeve pipes, be laid with optical fiber in the every loose sleeve pipe, loose sleeve pipe coats oversheath outward, it is characterized in that tiling setting side by side about 2 loose sleeve pipes, both sides are installed on the fibre reinforced plastics supporting member up and down in oversheath.
2, by the described two loose sleeve pipe micro optical cables of claim 1, it is characterized in that described 2 parallel placements of loose sleeve pipe, the diameter of loose sleeve pipe is 1.6～2.1mm, and every loose sleeve pipe includes 2～12 optical fiber.
3,, it is characterized in that described fibre reinforced plastics supporting member symmetry is installed in oversheath interior both sides and 2 perpendicular directions of the loose sleeve pipe line of centres up and down by claim 1 or 2 described two loose sleeve pipe micro optical cables.
4, by claim 1 or 2 described two loose sleeve pipe micro optical cables, it is characterized in that loose sleeve pipe holds aramid fiber or water blocking yarn outward.
