Abstract
The invention discloses a micro butterfly optical cable, which comprises a butterfly sheath, optical fibers and reinforcing cores, wherein the optical fibers are at the central position of the butterfly sheath; the reinforcing cores are at two wings of the butterfly sheath; each reinforcing core consists of a middle polyethylene fiber bundle and a high-temperature resistant protection layer wrapped outside the middle fiber bundle; and the minimum bending radius of the optical fibers is less than 8 millimeters. The optical cable successfully realizes better flexibility and portability based on smaller structure, and the manufactured optical cable is still required with certain tensile strength and lateral impact resistance so as to ensure that the optical fibers are not damaged by an external force.
Description
Technical field
The invention discloses a kind of butterfly optical cable, be specifically related to a kind of miniature butterfly indoor leading-in optical cable.
Background technology
Indoor leading-in optical cable is that large-scale application is in FTTH(Fiber To The Home, Fiber to the home) optical cable of user's section of introducing in the network, also be applicable to other optical fiber accesses such as FTTO(Fiber To The Office, Fiber-To-The-Office) and FTTB(Fiber To The Building, FTTB) optical cable of user's section of introducing of network such as.Inside cable is mainly used in the house wiring stage.House wiring is the most complicated link in the whole optical fiber access engineering, and the mechanical propertys such as its bending property to optical cable, tensile property have very high requirement, and it is attractive in appearance convenient with laying to take into account again simultaneously.Now widely used is 2.0mm*3.0mm, and strengthening core is the butterfly leading in cable of glass fibre.Though the glass fibre strengthening core has tension, corrosion-resistant, lightning-arrest advantage of hitting, but easily fracture, weight more also becomes its deadly defect, when constructing, house wiring often easily because be bent and tied a knot and produce and fracture, cause the basic role of strengthening core to completely lose.Owing to the restriction of manufacture craft, the glass fibre strengthening core can not be made into more small structure simultaneously, so that can't be made into the butterfly leading in cable of microstructure.
Summary of the invention
For defects, the object of the invention provides the miniature butterfly indoor leading-in optical cable of a kind of bend resistance.
For achieving the above object, the technical solution used in the present invention is:
A kind of miniature butterfly optical cable of the present invention; comprise butterfly sheath, optical fiber, strengthening core; described optical fiber is in described butterfly sheath center; strengthening core is at butterfly sheath both wings; it is characterized in that; described strengthening core is comprised of the middle polyethylene fibre bundle high temperature resistance protective layer outer with being coated on described median fiber bundle, and described optical fiber minimum bending radius is less than 8mm.
In a preferred embodiment of the present invention, described polyethylene fibre bundle is intensity〉35g/d, modulus〉1100g/d high-strength high-modulus polyethylene fiber bundle.
In a preferred embodiment of the present invention, the diameter of described fibrous bundle is 0.2～0.5mm.
In a preferred embodiment of the present invention, but described protective seam is the heatproof degree greater than 200 ℃ polyester copolymer.
In a preferred embodiment of the present invention, described protective layer thickness is 0.03～0.1mm.
In a preferred embodiment of the present invention, described butterfly sheath is low-smoke halogen-free flame-retardant sheath.
In a preferred embodiment of the present invention, described optical fiber is G657.B optical fiber.
In a preferred embodiment of the present invention, described optical cable sectional dimension is less than 2.0mm*3.0mm.
The present invention is compared with existing technology and has the following advantages: cable configuration of the present invention is on miniaturization basis more, success realizes better flexibility and portability, but still the optical cable that requires to make has certain stretch-proof performance and side impact resistance injury-free when being subject to external force to guarantee optical fiber wherein.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the present invention.
Wherein 1 is the butterfly sheath, and 2 is optical fiber, and 3 is fibrous bundle, and 4 is protective seam.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that protection scope of the present invention is made more explicit defining.
As shown in Figure 1; optical cable of the present invention comprises butterfly sheath 1, optical fiber 2, strengthening core; strengthening core is comprised of median fiber bundle 3 and the protective seams that are coated on outside the described median fiber bundle 3; it is the intensity of 0.2～0.5mm that described fibrous bundle preferably adopts diameter〉35g/d, modulus〉1100g/d high-strength high-modulus polyethylene fiber bundle; the protective seam of high temperature resistant, anti-folding polyester copolymer material formation that protective seam preferably adopts; the heatproof degree is greater than 200 ℃; thickness is 0.03～0.1mm, and made strengthening core can anti-high temperature more than 200 ℃.Optical fiber 2 is in described butterfly sheath 1 center, and optical fiber can be one or more, preferably adopts the G657.B optical fiber about bending radius 7.5mm; Strengthening core is at butterfly sheath 1 both wings, and butterfly sheath 1 preferably adopts the low-smoke halogen-free flame-retardant sheath of environmental protection.The overall dimensions of optical cable of the present invention is less than stock size 2.0mm*3.0mm.
The manufacturing process of optical cable of the present invention: a coiled optical fiber and two dish strengthening cores are positioned on the active actinobacillus frame of Φ 50mm extruder, and tension force control is as follows: strengthening core is 1.2N ± 0.2N, and optical fiber is 1N ± 0.2N.Optical fiber is passed through butterfly optical cable mold center aperture, two strengthening cores are parallel with central optical fiber, left-right symmetric splits in the optical fiber both sides and by the butterfly optical cable mould, and control Φ 50mm extruder is extruded the cable outer sheath material makes its complete packet overlay on optical fiber and strengthening core surface to make the butterfly leading in cable.In the stranding process, the control of Φ 50mm extruder parameter is as follows: the first district (screw rod back zone) 130 ± 5 ℃, 140 ± 5 ℃ of Second Regions (distinguishing in the screw rod), the 3rd district (screw rod back zone) 155 ± 5 ℃, the 4th district (machine neck) 165 ± 5 ℃, the 5th district (head) 165 ± 5 ℃, linear velocity processed :≤80m/min.This optical cable has overcome the problems such as bending property that present optical cable exists is poor, when guaranteeing the physical strengths such as optical cable tensile, crushing resistance, realizes the good advantage of optical cable pliability.
The above; it only is the specific embodiment of the present invention; but protection scope of the present invention is not limited to this; any those of ordinary skill in the art are in the disclosed technical scope of the present invention; variation or the replacement that can expect without creative work all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claims were limited.
