Abstract
The utility model discloses a multi-core easily-branched butterfly-shaped leading-in optical cable for FTTH (Fiber To The Home). The multi-core easily-branched butterfly-shaped leading-in optical cable is characterized in that a plurality of butterfly-shaped leading-in optical cables are twisted at the periphery of a central reinforcing piece by proper pitch, are longitudinally wrapped with wrapping tapes and fixed, and then a layer of protective sleeve is extruded; and a cable opening rope is arranged between the protective sleeve and the longitudinal wrapping tape, and is used for peeling the protective sleeve in construction. The multi-core easily-branched butterfly-shaped leading-in optical cable disclosed by the utility model has the advantages that the core number of the optical cable is designed according to the actual need, and the requirement for multipoint access is met; all-dielectric and all-dry type structural design is achieved, the construction is clean and sanitary, and the current low-carbon and environmentally-friendly requirements are met; and the butterfly-shaped leading-in optical cable is adopted as a cable-forming small unit so as to be matched with a site fast connector for use, and fast end forming can be achieved, and the defect of welding into the end is avoided.
Description
Technical field
The utility model FTTH is to be applied in the Access Network corridor wiring with multicore branch butterfly leading in cable, and the supporting use of on-the-spot quick coupler is connected between corridor beam split fiber-dividing box and the family information Multi-media box, realizes that Fiber to the home, the raising transmission bandwidth.
Background technology
Available the turning out a prestigious institution of FTTH development at home described since 2008; Domestic three big operators carry out like a raging firely to the concentrated bid and purchase work of butterfly leading in cable; The physical connection that the user inserts has also realized " light advances copper and moves back "; This so-called new product of butterfly leading in cable, the ordinary people can be not strange.Along with the rise of broadband upsurge in construction, butterfly optical cable is come into every household by feat of low-cost, high efficiency advantage, and every household all can insert the butterfly leading in cable.But in the construction of reality; Butterfly leading in cable of every household cloth again and again; The simple work let us that repeats has had a kind of like this query: can design the easily branched type butterfly of a kind of multicore leading in cable, reduce the continuous upstairs house that repeats and come and go wiring down, put forward same efficient.
Summary of the invention
The purpose of the utility model is to above-mentioned weak point; Provide FTTH with the easily branched butterfly leading in cable of multicore; Many butterfly leading in cables are stranded in around the central reinforce member with suitable pitch, carry out firmly with the vertical packet mode of band, and then extrude one deck sheath.Be provided with out hawser at the vertical parlor of sheath and band, be used for out the stripping sheath during construction.FTTH can design the core number of optical cable according to the actual requirements with the easily branched butterfly leading in cable of multicore, satisfies the requirement that multiple spot inserts; Full medium, dry type structural design, cleaning, health meet current low-carbon (LC), environmental requirement during construction; Adopt the butterfly leading in cable as the stranding junior unit, the use of supporting on-the-spot quick coupler, Cheng Duan rapidly avoids being fused into the shortcoming of end.
Above-mentioned FTTH is with the easily branched butterfly leading in cable of multicore, and its special sheet is that said optical cable comprises multicore butterfly leading in cable; Cable configuration can realize opening fast the stripping difference; Said oversheath adopts the low smoke and zero halogen material after high-temperature fusion, through wrapping on the cable core after the mold cools down typing.
FTTH of the present invention is reasonable with the global design of the easily branched butterfly leading in cable of multicore, compact conformation, and the manufacture craft flow process is reliable.The FTTH that makes through the present invention has following characteristics with the easily branched butterfly leading in cable of multicore:
1. full medium, dry type structural design reduce construction pollution, and coloured silk is used the low smoke and zero halogen sheath material, meets green, environmental protection concept.
2. optical cable is a multicore structure, and the maximum core number can reach 50 cores, and disposable laying puts in place, reduces and repeats wiring, has discharged valuable line resource when improving operating efficiency again.
3. adopt the subelement of butterfly leading in cable as stranding, the scene can rapid-resultly soon be held, and effectively avoids the loaded down with trivial details problem of on-the-spot welding, easy construction.
4. open hawser at band and vertical setting of sheath, difference is convenient and swift.
Description of drawings
Fig. 1 is that this practical FTTH is with the easily branched butterfly leading in cable of multicore cross-sectional structure synoptic diagram.
Embodiment
Below will combine accompanying drawing that the utility model is described further.
Fig. 1 is that this practical FTTH is with the easily branched butterfly leading in cable of multicore cross-sectional structure synoptic diagram.
With reference to accompanying drawing 1; Adopt nonmetal central reinforce member 5 to place the center of optical cable, with the stranded butterfly leading in cable 4 of suitable pitch, outside band 3 adopts vertical job contract skill closely to be coated on around the cable core in an orderly manner around nonmetal central reinforce member 5; With the fixed light cable structure, extrude sheath 1 at last.Between sheath 1 and band 3, place and open hawser 2.
The FTTH of present embodiment takes following scheme to realize with the easily branched butterfly leading in cable of multicore:
Nonmetal center stiffener from gantry pay off rack emit through tension traction wheel; The multicore butterfly optical cable adopts strand cage pay off rack, through tenslator, is stranded in around the stiffener of nonmetal center with certain stable pitch spiral; Before getting into the extruder head mould, adopt the vertical bag of band; To form stable structure, plastics are extruded on the cable core through the mould through customization after the high-temperature fusion equably, between band and sheath, place one and open hawser.Through the cooling of hot and cold water two-stage cooling system, dry up in the crawling traction take-up of back and coil then.
Though the present invention with preferred embodiment openly as above, they are not to be used for limiting the present invention, anyly have the knack of this art, in spirit that does not break away from the present invention and scope, 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.
