Abstract
The utility model discloses an ultra-soft bending-resistant high-strength FTTH (fiber to the home) butterfly-shaped optical cable, which is characterized by consisting of reinforcement pieces made of high-strength synthetic fibers, an optical fiber hole in the middle, and a butterfly-shaped sheath, wherein optical fibers are arranged in the optical fiber hole; at least two high-strength synthetic fiber reinforcement pieces are arranged, and the optical fibers are arranged in the middle of the reinforcement pieces; the optical fibers and the high-strength synthetic fiber reinforcement pieces are externally extruded with a layer of the butterfly-shaped outer sheath; the high-strength synthetic fiber is made from PPTA (poly-p-phenylene terephthamide); and the butterfly-shaped outer sheath is made in the way that a plastic material is molten at high temperature and then is cooled and molded by a mold. The ultra-soft bending-resistant high-strength FTTH butterfly-shaped optical cable has the advantages that the whole structure is small in outer diameter and light in weight; fragrance fiber reinforcement is adopted, so that the strength and the flexibility are very high; and a flame-retardant environment-friendly material is adopted, so that the requirement of indoor wire distribution of a user is met.
Description
Technical field
The super gentle anti-curved high-strength F TTH butterfly optical cable of the utility model relates to is the optical cable of last kilometer in a kind of Access Network that is applied to that Fiber to the home, cooperates quick coupler to use, and is connected to quickly and easily on the indoor terminal equipment.
Background technology
Along with fiber-to-the-home arriving, optical fiber is about to enter among the huge numbers of families, and the tracking to the optical cable of registering one's residence is comparatively extensive with research both at home and abroad in recent years, and each businessman releases the optical cable of registering one's residence of different size model, and the typical case is exactly a butterfly optical cable the most.
Traditional butterfly optical cable adopts minor diameter steel wire or FRP to bear mechanical pulling force as reinforcing element.Adopt the butterfly optical cable of these two kinds of reinforcing elements in work progress, depositing inevasible difficult situation: if adopt thin diameter wire to satisfy request for utilization undoubtedly as its pulling force of butterfly optical cable of reinforcing element, but when walking, pipeline through regular meeting the jam phenomenon takes place, tracing it to its cause is that thin diameter wire bending property is undesirable, and jam is in the pipeline corner easily; If adopt FRP to be greatly improved, but there are very big defective in its bending and mechanical pulling force characteristic, construct to finish after there is the phenomenon of disconnected fibre or disconnected cable in regular meeting as the butterfly optical cable bending property of reinforcing element butterfly optical cable with respect to the metal strengthening core.
Summary of the invention
The purpose of this utility model is at above-mentioned weak point, and a kind of super gentle anti-curved high-strength F TTH butterfly optical cable is provided, and has excellent physical strength, good pliability and fold resistance.Adopt high strength synthetic fibre (PPTA) optic fibre hole, the design of butterfly appearance to be set as reinforcing element, centre.Compare with traditional butterfly optical cable, have advantages such as intensity height, anti-curved anti-folding.
Realization technical scheme of the present utility model is: a kind of super gentle anti-curved high-strength F TTH butterfly optical cable, it is characterized in that, adopt high strength synthetic fibre optic fibre hole, butterfly appearance sheath composition to be set as reinforcement, centre, optical fiber places optic fibre hole, at least two of described high strength synthetic fibre reinforcements, the centre is provided with described optical fiber, extrudes the described butterfly appearance of one deck sheath outside described optical fiber and the high strength synthetic fibre reinforcement.
Above-mentioned super gentle anti-curved high-strength F TTH butterfly optical cable, it is characterized in that: described high strength synthetic fibre is a kind of PPTA; Described butterfly appearance sheath be a kind of plastic raw materials after high-temperature fusion, finalize the design by mold cools down.
Super gentle anti-curved high-strength F TTH butterfly optical cable of the present invention global design is reasonable, compact conformation, and the manufacture craft flow process is reliable.The super gentle anti-curved high-strength F TTH butterfly optical cable of making through the present invention has following characteristics:
1. the one-piece construction external diameter is little, and is in light weight.
2. adopt virtue dimension fiber to strengthen, have very high intensity and pliability.
3. adopt the flame-proof environmental protection material, satisfy the demand of user's house wiring.
Description of drawings
Fig. 1 is the super gentle anti-curved high-strength F TTH butterfly optical cable cross-sectional structure synoptic diagram of the utility model.
Embodiment
The utility model is described in further detail below with reference to accompanying drawing.
Fig. 1 is a super gentle anti-curved high-strength F TTH butterfly optical cable cross-sectional structure synoptic diagram described in the utility model.
With reference to accompanying drawing 1, optical fiber 2 places in the middle of aramid fiber reinforcement 1 and the aramid fiber reinforcement 3, extrudes the sheath 4 of the shape of one deck shape such as butterfly outside this.
The super gentle anti-curved high-strength F TTH butterfly optical cable of present embodiment takes following scheme to realize: optical fiber is emitted by corresponding pay off rack with reinforcing fibre, enters extruder head with the doubling of doubling mould; Plastic raw materials is molten condition after heating through machine barrel high temperature, coat optical fiber and reinforcing fibre tight by specific extrusion die, and relatively-stationary position, enter the warm water cooling system and enter the cold water cooling again, the butterfly optical cable after the typing is coiled in the take-up after going up through the Tension Control measuring system to the production line traction through caliper.
Though the present invention is with preferred embodiment openly as above, they are not to be used for limiting the present invention, anyly have the knack of this skill person, without departing from the spirit and scope of the invention, and certainly when doing various variations or retouching, all within protection scope of the present invention.What therefore protection scope of the present invention should be defined with the application's claim protection domain is as the criterion.
Claims (2)
1. super gentle anti-curved high-strength F TTH butterfly optical cable, it is characterized in that: adopt high strength synthetic fibre optic fibre hole, butterfly appearance sheath composition to be set as reinforcement, centre, optical fiber places optic fibre hole, at least two of described high strength synthetic fibre reinforcements, the centre is provided with described optical fiber, extrudes the described butterfly appearance of one deck sheath outside described optical fiber and the high strength synthetic fibre reinforcement.
