Abstract
The utility model relates to a central tube type air blowing micro cable. The micro cable comprises an outer sheath and a loose sleeve which is covered with the outer sheath. The micro cable is characterized in that: an optical cable unit laid in the loose sleeve is an optical fiber belt. A non-metallic reinforcing element is laid between the outer sheath and the loose sleeve. The central tube type air blowing micro cable has the following beneficial effects that: 1 small diameter, light weight, convenient air blowing layout and long air blowing distance; 2 simple structure, high tensile property, good flexibility, and correspondence with the low carbon environmental protection requirement; 3 full optical fiber belt structure, greatly shortened fiber welding time when the branched cables are connected, increased construction efficiency, and reduced project cost.
Description
Technical field
The utility model relates to a kind of central tubular air-blowing minisize optical cable, can carry out air-blown installation at micro plastic pipeline.
Background technology
Along with FTTH is fast-developing, in Metropolitan Area Network (MAN) and Access Network, micro optical cable has been widely used in the fiber cable network of air-blown installation.Due to the limitation of conduit resource, air-blowing distance and easy to use be generally requirement to all products.Existing air-blowing minisize optical cable has layer-twisted type and two kinds of structures of central tubular, and these two kinds of structures all adopt loose fine version at present.No matter be central tubular air-blowing micro-cable or layer-twisted type air-blowing micro-cable, though efficiency is improved aspect fiber cable laying, the efficiency of fibre junction is still waited to improve.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of central tubular air-blowing minisize optical cable for the deficiency of above-mentioned prior art existence, and it is good that it has the performance of laying, air-blowing distance, the simple in structure and high feature of efficiency that continues.
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 oversheath loose sleeve pipe, it is characterized in that the fiber unit laying is fibre ribbon in loose sleeve pipe.
Press such scheme, between oversheath and loose sleeve pipe, be laid with nonmetal reinforcing element.
Press such scheme, the core number of described fibre ribbon is 4 ~ 12 cores.
Press such scheme, described fibre ribbon is 1 ~ 12, parallel superimposed laying.
Press such scheme, described oversheath is made by HDPE or bittern-free flame-proof material.
The beneficial effects of the utility model are: 1, diameter is little, lightweight, are convenient to air-blown installation and air-blowing distance; 2, simple in structure, pull resistance is strong, flexible, and meets low-carbon environment-friendly requirement; 3, full band structure of optic fibre, has reduced the molten fine time greatly when difference continues, improved operating efficiency, has reduced engineering cost.
Accompanying drawing explanation
Fig. 1 is the radial section sectional view of an embodiment of the utility model.
Fig. 2 is the radial section sectional view of another embodiment of the utility model.
Fig. 3 is the radial section sectional view of the 3rd embodiment of the utility model.
Embodiment
Below in conjunction with accompanying drawing, further illustrate embodiment of the present utility model.
First embodiment as shown in Figure 1, include oversheath 1 and be coated in oversheath loose sleeve pipe 3, in loose sleeve pipe, be laid with the fibre ribbon 4 of 2 12 cores, in loose sleeve pipe, be filled with and touch the fine cream 5 of strain; Described oversheath is made by halogen-free low-smoke flame retardant material; Between oversheath and loose sleeve pipe, lay and be coated with nonmetal reinforcing element 2, described nonmetal reinforcing element is aramid yarn.
As shown in Figure 2, difference is to be laid with in described loose sleeve pipe the fibre ribbon 4 of 12 12 cores to second embodiment.
As shown in Figure 3, difference is to be laid with in described loose sleeve pipe the fibre ribbon 4 of 46 cores to the 3rd embodiment.
