Abstract
The utility model relates to an all-dielectric miniature optical cable for a single loose sleeve capable of carrying out air blast lying in a miniature plastic pipeline. The all-dielectric miniature optical cable comprises a loose sleeve; an optical fiber is laid in the loose sleeve; and an outer sheath is enwrapped outside the loose sleeve, The all-dielectric miniature optical cable is characterized in that the loose sleeve is mounted on one side of the outer sheath; and a fiber reinforced plastic bearing part is mounted in the outer sheath corresponding to the other side of the loose sleeve. The radial section of the outer sheath is circular; and one fiber reinforced plastic bearing part is provided and straightly laid on the other side in the outer sheath. The utility model has the advantages that firstly, compared with the prior central beam tube type structure, the outer sheath is not retracted and the residue length of the optical fiber is more stable; secondly, the single single-layered loose sleeve is adopted and the double-layered loose sleeve is not adopted, so that the external diameter of the loose sleeve is reduced and the material cost and the processing cost of the optic cable are reduced; and thirdly, the optic cable has small external diameter and light weight and can carry out air blast laying in the smaller plastic pipe along a longer distance.
Description
Technical field
The utility model relates to a kind of full medium micro optical cable of single loose sleeve pipe 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 fiber cable network of air-blown installation.Existing micro optical cable has the central beam tube type structure, be about to optical fiber and be sleeved in the loose sleeve pipe, outside loose sleeve pipe, coat oversheath again and constitute, adopt this structure when oversheath bounce back, to be easy to cause loose sleeve pipe to bounce back, and loose sleeve pipe retraction will cause that excess fiber length becomes big in the pipe, and optical property descends.Existing central beam tube type micro optical cable adopts double-deck loose sleeve structure to prevent retraction usually.Double-deck loose sleeve pipe complex manufacturing technology, thereby the cost of manufacture of central beam tube type micro optical cable is higher relatively.
Summary of the invention
Technical problem to be solved in the utility model is to provide the single loose sleeve pipe that a kind of structure is provided with rationally, cost of manufacture is lower full medium micro optical cable at the deficiency of above-mentioned prior art existence.
The utility model is that the technical scheme that problem adopted of the above-mentioned proposition of solution is: include 1 loose sleeve pipe, be laid with optical fiber in the pine sleeve pipe, the pine sleeve pipe coats oversheath outward, it is characterized in that described loose sleeve pipe is installed in a side in the oversheath, the opposite side of corresponding loose sleeve pipe is installed on the fibre reinforced plastics supporting member in oversheath.
Press such scheme, described oversheath radial section is circular, and described fibre reinforced plastics supporting member is 1, the straight interior opposite side of oversheath that is laid on.
Press such scheme, described loose sleeve pipe and fibre reinforced plastics supporting member parallel interval are laid on both sides in the oversheath; The fibre reinforced plastics supporting member is all coated by the oversheath material.
Press such scheme, the diameter of described loose sleeve pipe is 1.5～2.4mm, and loose sleeve pipe includes 1～12 optical fiber.
The beneficial effects of the utility model are: 1, compare with existing central beam tube type structure, oversheath does not bounce back, and optical fiber excess length is more stable; 2, adopt single individual layer pine sleeve pipe, needn't adopt double-deck loose sleeve pipe, dwindled loose cover external diameter of pipe, reduced the material cost and the processing cost of optical cable; 3, cable outer diameter is little, in light weight, can be long apart from the ground air-blown installation in less plastic tube.
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 1 loose sleeve pipe 3, be the loose sleeve pipe of polybutylene terephthalate (PBT), be laid with the fine cream 1 of optical fiber 2 and filling in the pine sleeve pipe, the diameter of pine sleeve pipe can be 1.5～2.4mm, 1～12 of interior dress single beam fibre, loose sleeve pipe holds aramid yarn or water blocking yarn 5 outward, coats oversheath 4 outward, oversheath available polyethylene (PE), bittern-free flame-proof material or nylon material are made, and constitute the rounded full medium micro optical cable of radial section.Be provided with 1 fibre reinforced plastics supporting member 6 at oversheath, diameter is 0.25～1.0mm, and the fibre reinforced plastics supporting member is all coated by the oversheath material.The pine sleeve pipe is installed a side in oversheath, pine cover tube hub and oversheath center are at a distance of 0.5～1.5mm, corresponding loose sleeve pipe fibre reinforced plastics supporting member is arranged at opposite side in the oversheath, fibre reinforced plastics supporting member center and oversheath center are separated by the oversheath material between the two at a distance of 0.5～1.5mm.
