Abstract
The utility model reveals a pipeline type FTTH butterfly optical cable, comprising an optical fiber, a reinforcement member, a butterfly sheath, a strengthening member, a wrapping tape, an aluminum tape and a protective sleeve, wherein the cross section of the butterfly sheath is a circle with gaps at two sides. According to the utility model, since the butterfly sheath of the pipeline type FTTH butterfly optical cable is substantially a cylinder with triangular gaps at two sides, the gaps of the butterfly sheath may be large or small during stretching or distorting of the whole butterfly optical cable, and thus, bending performance and tensile strength of the butterfly optical cable are improved, and the pipeline type FTTH butterfly optical cable is applicable to vertical wiring, horizontal wiring and pipeline wiring in an FTTH building.
Description
Technical field
The utility model relates to the optical cable field, particularly a kind of optical cable that inserts for Fiber to the home (FTTH).
Background technology
Along with development of fiber technology, the application that Fiber to the home (FTTH) more and more widely.At present, common butterfly optical cable technology is ripe relatively, and its primary structure is as follows: the parallel reinforcement flat structure of colored optical fiber, tightly packaged fiber add parallel reinforcement structure, fibre ribbon and add parallel reinforcement flat structure and fibre ribbon and add parallel adding and force the suspention flat structure.Though flat structure is in that to separate optical fiber and anti-pressure ability comparatively outstanding, its bendability in certain direction exists defective and tensile resistence limited.
The utility model content
The purpose of this utility model is the defective that overcomes in the background technology, the pipeline FTTH butterfly optical cable that provides a kind of bending property and stretch-proof performance to take into account.
In order to achieve the above object, the technical solution adopted in the utility model is as follows:
A kind of pipeline type FTTH butterfly optical cable comprises optical fiber, reinforcement, butterfly sheath, reinforcement, band, aluminium strip and protective sleeve, it is characterized in that: described butterfly sheath xsect is the circle that both sides have breach.
Further, for conserve space, reduce the optical cable overall dimensions, described reinforcement is positioned at the breach of butterfly sheath.
Further, the number of described optical fiber is 1～4.
Further, the number of described optical fiber is 2.
Compared with prior art, the beneficial effects of the utility model are:
The butterfly sheath of the utility model pipeline type FTTH butterfly optical cable roughly is both sides the cylindrical of triangular cut, therefore when whole butterfly optical cable being stretched or twists, the breach of butterfly sheath is changeable, thereby increased bending property and the stretch-proof performance of butterfly optical cable, be applicable to vertical wirings and horizontal wiring and pipeline wiring in the FTTH building.
Description of drawings
Fig. 1 is the cross sectional representation of the FTTH butterfly optical cable of the utility model embodiment.
Embodiment
Below in conjunction with embodiment and contrast accompanying drawing this utility pipes type FTTH butterfly optical cable is further elaborated.
As shown in Figure 1, be a preferred embodiment of the present utility model.
The utility model has disclosed a kind of pipeline type FTTH butterfly optical cable 10, comprises optical fiber 6, reinforcement 7, butterfly sheath 8, reinforcement 5, band 3, aluminium strip 2 and protective sleeve 1.
Described optical fiber 6 adopts the G657A2 colored optical fibers, be blue in the time of piece, is respectively blue, orange dichromatism in the time of two, is respectively blue, orange, green, color in brown four in the time of four.
Described reinforcement 7 is two, can select glass fibre FRP for use, and diameter is 0.5mm～0.6mm, is positioned at optical fiber 6 both sides of butterfly sheath 8.
Described butterfly sheath 8 xsects are roughly rounded, and dual-side is symmetrically formed breach 4.
Described reinforcement 5 can adopt the phosphatization steel wire, is positioned at the breach 4 of butterfly sheath 8 both sides.
Above content be in conjunction with concrete preferred implementation to further describing that the utility model is done, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design, make some alternative or obvious modification that are equal to; and performance or purposes are identical, all should be considered as belonging to the scope of patent protection that the utility model is determined by claims of submitting to.
Claims (4)
