Abstract

The utility model is a self-supporting multi-core wiring butterfly cable, which relates to the technical field of optical cables. The self-supporting multi-core wiring butterfly cable comprises steel twisted wires, a high-density sheath, an aramid reinforced layer, a butterfly cable inner sheath, an optical fiber, cable reinforcing pieces and an optical fiber, wherein the surface of each optical fiber is coated with a colored ink layer used for protecting the optical fiber, the two reinforcing pieces and the optical fibers are simultaneously placed in the butterfly cable inner sheath in parallel, the aramid reinforced layer wraps the butterfly cable inner sheath and is wrapped by the high-density sheath, and the steel twisted wires are wrapped outside and connected with the high-density sheath. The butterfly cable inner sheath is a low-smoke halogen-free sheath; and the cable reinforcing pieces are steel wires or FRPs. The self-supporting multi-core wiring butterfly cable can meet the requirements of long distance transmission and can be segmented in use, the outer sheath layer can be torn and the inner sheath cable can be taken out and used alone when the cable reaches a certain length, and the cable has high flexibility; as the butterfly cable inner sheath is built in the cable, all performances of an original butterfly cable can be retained even if the cable need to be branched in use; and the optical fibers built in the butterfly cable can be one-core or multi-core optical fibers, and a whole line can be reserved for use.

Description

Self supporting type multi-core distribution butterfly cable

Technical field

The utility model relates to the optical cable technology field, but it is a kind of self supporting type multi-core distribution butterfly cable in definite saying.

Background technology

domestic leading TD-LTE formally becomes the 4G international standard in January, 2012 at present, formal prologue is gone on an expedition in the whole world that this means the next generation mobile communication standard, set up just step by step the mobile communication standard system of oneself from 3G to 4G China, numerous and confused this business of releasing is given birth in each operation of present stage, and set up pilot on Guangzhou and other places, estimate to reach soon the whole nation in the future universal, having relatively high expectations of the relatively whole networking of 4G, particularly the major function of band width service LTE is to provide wireless network traffic, thereby realize the wireless city concept, with respect to present stage wireless network circuit, mainly to be connected to terminal device with ordinary optical cable, realize wireless network.But the optical cable that existing line adopts generally mostly is the plain edition optical cable, lacks dirigibility, construction is loaded down with trivial details, efficient is lower, and is as not in place in protection in shunt, directly affects transmission performance.

Summary of the invention

The purpose of this utility model is to provide a kind of multicore distribution butterfly cable, can improve deficiency of the prior art, increases line construction various, and operation and method more easily are provided.

The technical scheme that the utility model technical solution problem adopts is: optical fiber surface applies the printing ink of the coloured protection optical fiber of one deck band; metal reinforcement and optical fiber is simultaneously parallel is placed on sheath in the butterfly cable; after many butterfly optical cables are stranded; be wound around one deck high strength aramid yarn, simultaneously with the parallel sheath high density of steel wire twisted wire PE material stranding.Specifically; it comprises sheath, optical fiber, cable reinforcement, optical fiber in steel wire twisted wire, high density sheath, aramid fiber reinforcement, dish-shaped cable; it is characterized in that: optical fiber surface applies the ink lay of the coloured protection optical fiber of one deck band; two reinforcements and optical fiber is simultaneously parallel to be placed in the butterfly cable in sheath; the aramid fiber enhancement Layer holds sheath in the butterfly cable; outsourcing high density sheath holds the steel wire twisted wire outside the high density sheath and the high density sheath links together.In the butterfly cable, sheath is the low smoke halogen-free sheath.The cable reinforcement is steel wire or FRP.

The utility model has the advantages that:

But 1 self-bearing type hangs on shaft tower or is suspended from pipeline;

2, high strength aramid fiber reinforcing element makes optical cable that the mechanical propertys such as higher anti-collapse, stretching, bending, stretching be arranged, thereby can guarantee the application of various scenes.

3, can satisfy long Distance Transmission, also sectional uses, and when arriving a certain segment length, the tearable outer jacket protects optical cable in taking out separately and uses, and dirigibility is high;

4, protect cable in built-in butterfly, branch uses as need, still keeps the over-all properties of original butterfly cable;

5, butterfly cable built-in fiber can adopt a core or multicore, provides the whole piece circuit to reserve and uses;

6, independent butterfly cable simultaneously can be according to device port, field fabrication quick coupler FC LC the joint such as SC, can improve construction of line speed.

7, the dry type pattern without the ointment that blocks water, has guaranteed the cleanliness factor of working-yard.

8, this optical cable can satisfy the networking of FTTX simultaneously, and higher construction dirigibility and practicality are arranged equally.

Description of drawings

Fig. 1 is structural representation of the present utility model.

Fig. 2 is process chart of the present utility model.

In figure, 1 is the steel wire twisted wire, and 2 is the high density oversheath, and 3 strengthen for aramid fiber, and 4 for protecting in low smoke and zero halogen, and 5 is optical fiber, and 6 is stiffener.

Specific embodiments

The utility model by optical fiber, in protect in reinforcement (metal, non-metal type), low smoke and zero halogen and protect, form in butterfly and protect cable, by protecting outside cable in many stranded butterflies, be wound around one deck high strength aramid yarn, extrude one deck high density protective cover material stranding by steel wire twisted wire sheath parallel with cable core again, its purpose improves the properties of optical cable in application, and diversified wiring mode improves the operability of construction simultaneously.Concrete structure is self supporting type multi-core distribution butterfly cable; comprise sheath, optical fiber, cable reinforcement, optical fiber in steel wire twisted wire, high density sheath, aramid fiber reinforcement, dish-shaped cable; optical fiber surface applies the ink lay of the coloured protection optical fiber 5 of one deck band; two reinforcements 6 and optical fiber 5 is simultaneously parallel to be placed in the butterfly cable in sheath; aramid fiber enhancement Layer 3 holds sheath 4 in the butterfly cable; outsourcing high density sheath 2 holds steel wire twisted wire 1 and links together with high density sheath 2 outside high density sheath 2.In the butterfly cable, sheath 4 is the low smoke halogen-free sheath.Cable reinforcement 6 is steel wire or FRP.
