Abstract
The utility model relates to the technical field of communication optical cables, in particular to an ultra-miniature air-blown optical cable. The ultra-miniature air-blown optical cable comprises at least one loose tube, wherein a plurality of optical fibers are wrapped in the loose tube, and fiber paste is filled in the loose tube. An outer sheath sleeves the loose tube, a plurality of saw-toothed teeth are annularly arranged on the outer side wall of the outer sheath, and cross sections of the teeth are trapezoid. When the ultra-miniature air-blown optical cable is used, small-diameter optical fibers and a special plastic are adopted to manufacture the loose tube, the outer diameter of the optical cable is decreased, the smooth and round outer sheath is changed to be a surface saw-toothed outer sheath, the micro-cable air-blown performance is obviously improved, the optical fiber density in a communication pipeline is increased, a low-cost solution method is provided for expansion of a communication network and building of a high-capacity network, and additional attenuation of the buried optical fibers is also reduced obviously. The ultra-miniature air-blown optical cable has the advantages of being simple in structure, reasonable in setting, low in manufacture cost and the like.
Description
Technical field
The utility model relates to communications optical cable technical field, particularly superminiature air-blowing optical cable.
Background technology
Along with the development of communication network, original conduit resource cannot meet the demand of network expansion, and newly-built communication pipe faces, cost is high, difficulty of construction large, communal facility is destroyed and affect the problems such as periphery traffic, environment.And air-blowing Microtubule micro cable technology, Microtubule micro cable technology has solved this problem to a great extent, can in a silicon core pipe, be blown into several microtubules (can be blown into 5 10/8 microtubules or 10 7/5.5 microtubules in as a 40/33mm pipe), also can in the silicon core pipe of existing optical cable, be blown into microtubule, then in microtubule, be blown into micro-cable.This technology can be utilized conduit resource fully, improves pipeline inner fiber density.
Reduce micro-cable diameter and be generally by reducing the casing diameter in cable core and outer retaining wall is thick realizes.But sleeve pipe and protect reducing that wall thickness dimension can not be unlimited outward, sleeve pipe is too small can increase the decay of optical fiber, reduce environmental performance and the mechanical property of optical cable, and wall thickness is crossed and thinly cannot effectively be protected cable core.Under current technique, the size of sleeve pipe and oversheath is almost reduced to the limit.
Air-blowing micro-cable has still continued the circular oversheath of PE of original ordinary optical cable, and in air-blowing process, the friction factor of PE oversheath and microtubule inwall is larger, and therefore air-blowing distance is also restricted.
Therefore necessary, the structure of existing air-blowing micro-cable is carried out to technical renovation further.
Utility model content
The purpose of this utility model is for the defect of prior art and deficiency, provides a kind of simple in structure, ultra-fine air-blowing micro-cable reasonable in design, easy to use.
For achieving the above object, the technical solution adopted in the utility model is:
Superminiature air-blowing optical cable described in the utility model, comprises and has a loose sleeve pipe at least, in described loose sleeve pipe, is wrapped in some optical fiber, in described loose sleeve pipe, is filled with fine cream; Pine sleeve pipe is arranged with oversheath outward, and the lateral wall annular of described oversheath is provided with several jagged teeth, and the xsect of described teeth is trapezoidal shape.
Further, the quantity of described loose sleeve pipe is one, and presumable reinforcement material is set between loose sleeve pipe and oversheath.
Further, it also comprises central reinforce member, and the quantity of described loose sleeve pipe is greater than one, and many loose sleeve pipes are twisted into cable core round central reinforce member by SZ, and cable core is outer to be wrapped in by oversheath.
Further, in described oversheath, be also filled with cable cream.
Adopt after said structure, the utility model beneficial effect is: superminiature air-blowing optical cable described in the utility model, and comprise and have a loose sleeve pipe at least, in described loose sleeve pipe, be wrapped in some optical fiber, in described loose sleeve pipe, be filled with fine cream; Pine sleeve pipe is arranged with oversheath outward, and the lateral wall annular of described oversheath is provided with several jagged teeth, and the xsect of described teeth is trapezoidal shape.When using the utility model, adopt smaller diameter fiber and special plastics to make loose sleeve pipe, reduce cable outer diameter and smooth circular oversheath is improved to surperficial teeth type oversheath, obviously improved the air-blowing performance of micro-cable, increased the density of optic fibre in communication pipe, for the dilatation of existing communication network with build witched-capacity network low-cost solution is provided, after laying, the additional attenuation of optical fiber also obviously reduces.The utlity model has simple in structurely, arrange rationally, the advantage such as cost of manufacture is low.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 1, superminiature air-blowing optical cable described in the utility model, comprises and has a loose sleeve pipe 4 at least, in described loose sleeve pipe 4, is wrapped in some optical fiber 1, and loose sleeve pipe 4 adopts high rigidity plastics, and as materials such as modified PBT, PC, the quantity of optical fiber 1 is 1～36; In described loose sleeve pipe 4, be filled with fine cream 2 or dry type material water-proof material, regulate in process of production core rod die sleeve size and the extrusion molding speed of extruding machine simultaneously, so just the diameter of loose sleeve pipe 4 further can be reduced.Pine sleeve pipe 4 is outer is arranged with oversheath 6, and the lateral wall annular of described oversheath 6 is provided with several jagged teeth, and the xsect of described teeth is trapezoidal shape, has so just obviously improved the air-blowing performance of micro-cable.
As shown in Figure 2, the quantity of described loose sleeve pipe 4 is one, and presumable reinforcement material 7 is set between loose sleeve pipe 4 and oversheath 6.
As shown in Figure 1, it also comprises central reinforce member 3, and the quantity of described loose sleeve pipe 4 is greater than one, and many loose sleeve pipes 4 are twisted into cable core round central reinforce member 3 by SZ, and cable core is outer to be wrapped in by oversheath 6.
Make a kind of optimal way of the present utility model, in described oversheath 6, be also filled with cable cream 5.
When using the utility model, adopt smaller diameter fiber and special plastics to make loose sleeve pipe, reduce cable outer diameter and smooth circular oversheath is improved to surperficial teeth type oversheath, obviously improved the air-blowing performance of micro-cable, increased the density of optic fibre in communication pipe, for the dilatation of existing communication network with build witched-capacity network low-cost solution is provided, after laying, the additional attenuation of optical fiber also obviously reduces.In addition, this is simple in structure, reasonable in design, low cost of manufacture.
The above is only better embodiment of the present utility model, and the equivalence of doing according to structure, feature and principle described in the utility model patent claim therefore all changes or modifies, and is included in the utility model patent claim.
