Abstract
The utility model discloses an fiber ribbon cable, comprising a central reinforcing part, a cannula of fiber ribbon matrix, interstitial wires, a polyester ribbon, a crimped metal composite ribbon and an outer sheath which are positioned in the cavity. The fiber ribbon matrix positioned in the cannula is intertwisted by six twelve-core fiber ribbons, which adopts the structure in four cannulas and the fiber core is up to 288. The utility model has the advantages of large containing information transmission, compact size, light weight, good mechanical performance, optical transmission performance, environment operating performance, well satisfaction for stand requirement of the laid city pipelines, more convenient construction, and raw material saving and low cost.
Description
Affiliated technical field
The utility model relates to a kind of communication apparatus, particularly a kind of optical fibre band optical cable.
Background technology
Along with the continuous development of network technology, the application and the communication need of internet (INTERNET) constantly enlarge, and the demand of network transmission capacity day by day sharply rises.Existing layer-twisted type optical fibre band optical cable, by central reinforce member, the sleeve pipe, interstitial wire, polyester belt, steel band, oversheath that are placed with fibre ribbon in the six roots of sensation are formed, and have that the information transmission capacity is little, volume big, the shortcoming of Heavy Weight, are difficult to satisfy the needs of the network transmission capacity that expands day by day.If increase sleeve pipe quantity or increase casing diameter, must increase the area in optical cable cross section to reach the purpose that increases fiber number.Because the diameter of the municipal pipeline that now laid generally between 26～28mm, increases the optical cable area of section and must increase the difficulty of optical cable being put into the municipal pipeline that has laid, sometimes or even can't finish, cause very big time and physical waste.
Summary of the invention
The utility model is little at above-mentioned transmission capacity, volume is big and the shortcoming of Heavy Weight, proposes that a kind of transmission capacity is big, volume is little and lightweight optical fibre band optical cable.
The utility model is achieved in that a kind of optical fibre band optical cable, comprise central reinforce member, sleeve pipe, fibre ribbon, interstitial wire, polyester belt, wrinkle metal compound belt, oversheath, it is characterized in that: sleeve pipe is stranded on the central reinforce member, is placed with fibre ribbon in the sleeve pipe; Fibre ribbon is the fibre ribbon matrix, and the fibre ribbon matrix forms by several fibre ribbons are stranded.
Above-mentioned sleeve pipe sum is four.
Above-mentioned fibre ribbon matrix is by six stranded forming of fibre ribbon.
The fiber number of above-mentioned every fibre ribbon is 12 cores.
The overall diameter of above-mentioned oversheath is less than 21.5mm.
The utility model is equipped with the fibre ribbon matrix that is twisted into by six 12 core fibre bands by central reinforce member, in several sleeve pipe, interstitial wire, polyester belt, wrinkle metal compound belt, oversheath are formed, and the tight SZ of sleeve pipe is stranded on the central reinforce member.From the cross section of optical cable, sleeve pipe evenly distributes around central reinforce member, and four sleeve pipes are all circumscribed with central reinforce member, and adjacent two sleeve pipes are also circumscribed mutually.
Adopt the method for spiral combination that six 12 core fibre bands are twisted into a fibre ribbon matrix, adopting accurately control to part power a little puts the band method fibre ribbon matrix is put into the sleeve pipe coating, four sleeve pipe SZ that are placed with fiber matrix are twisted on central reinforce member, gap between sleeve pipe adds four interstitial wires, be wrapped in sleeve pipe and interstitial wire periphery with polyester belt, be wrapped in the polyester belt periphery with the wrinkle metal compound belt, one deck oversheath is wrapped in wrinkle steel band periphery again.
Realization of the present utility model can reach that transmission capacity is big, volume is little, lightweight effect.Fiber number reaches 288 cores, and the fiber number considerably beyond existing optical cable better satisfies the demand that transmission capacity increases severely day by day; Volume can be controlled in the 21.5mm, greatly convenient construction; Weight also greatly alleviates, and has reduced transportation cost; The utility model has also significantly reduced the raw materials consumption in the production run, has saved resource.
Mechanical property of the present utility model, optical property, environment runnability are good, all meet national sector standard " (Access Network the optical fibre band optical cable " (requirement of YD/T981.1～981.3--1998), reach the A grade standard, especially its physical dimension is littler than existing fiber band optical cable, transmission capacity satisfies the needs of existing environment better than the big characteristics of existing fiber band optical cable.
Description of drawings
Further specify below in conjunction with Fig. 1:
Fig. 1 is a schematic cross-section of the present utility model.
Embodiment
As can be seen from Figure 1, the utility model is by central reinforce member 1, be placed with the sleeve pipe 2 of the fibre ribbon matrix 3 that is twisted into by six 12 core fibre bands in four, article four, twisted pair wire 4, polyester belt 5, wrinkle steel band 6 and oversheath 7 are formed, the sleeve pipe 2SZ that is placed with the fibre ribbon matrix 3 that is twisted into by six 12 core fibre bands in four is stranded on the central reinforce member 1, space between the sleeve pipe 2 is filled with four twisted pair wires 4, sleeve pipe 2 and twisted pair wire 4 peripheries are wrapped in one deck polyester 5, polyester belt 5 closely contacts with twisted pair wire 4 with sleeve pipe 2, polyester belt 5 peripheries are wrapped in one deck wrinkle steel band 6, wrinkle steel band 6 closely contacts with polyester belt 5, wrinkle steel band periphery is wrapped in layer of polyethylene bonding oversheath 7, and oversheath 7 closely contacts with wrinkle steel band 6.
