Description
Technical field
The utility model relates to a kind of communication facilities, specifically a kind of butterfly optical cable.
Background technology
Butterfly optical cable is the optical cable of user's section of introducing in fiber to the home (FTTH) network, is widely used in Intelligent Building, digital cells, campus network and LAN (Local Area Network).The internal placement of existing butterfly optical cable has two optical fiber, and the fibre-optical splice mated with butterfly optical cable but can only be connected a wherein optical fiber, and another optical fiber construction complexity cannot use and cause idle, creates unnecessary waste, is further improved.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, provides a kind of Access Network butterfly leading in cable, and this optical cable effectively should be able to utilize two inner optical fiber, and has structure feature simple and easy for installation.
The technical solution of the utility model is: Access Network butterfly leading in cable, is characterized in that: this optical cable is the single fiber butterfly optical cable of pair of parallel layout; The sheath of these two single fiber butterfly optical cables is connected as a single entity and the connected position on sheath two sides is respectively shaped with a drop-center axially extended for separation two single fiber butterfly optical cables; Be furnished with an optical fiber in the sheath of every bar single fiber butterfly optical cable and be positioned at two reinforcements of optical fiber both sides, sheath two sides is respectively shaped with one and axially extends and for the side groove of ripping sheath.
In described Access Network butterfly leading in cable, the axis arranged of all reinforcements is at same plane and be positioned in the symmetrical center line of two butterfly optical cable xsect, thus forms the structure of the two butterfly optical cable of flat.
Described drop-center is identical with the shape of cross section of side groove.
Described reinforcement is that steel wire or FRP increase part.
Described sheath adopts low-smoke halogen-free flame retardant material or Polyvinylchloride material.
The beneficial effects of the utility model are:
Be furnished with an optical fiber in every bar single fiber butterfly optical cable of the present utility model and two single fiber butterfly optical cables can install a fibre-optical splice respectively, thus improve the utilization factor of optical fiber; Meanwhile, structure of the present utility model is comparatively simple, installs also very convenient.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model xsect.
Embodiment
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As shown in the figure, Access Network butterfly leading in cable, comprises two single fiber (simple optical fiber) butterfly optical cables; These two single fiber butterfly optical cables are arranged in parallel and the sheath 1 of two single fiber butterfly optical cables is connected as a single entity (two the sheath of single fiber butterfly optical cable forms a banded ennation); An axially extended drop-center 2 is shaped with respectively at the connected position of these two single fiber butterfly optical cable sheath two sides (upper and lower surface in figure); Two single fiber butterfly optical cables are exerted oneself with different directions, the line direction of two drop-centers in sheath (in figure shown in A) just can be forced to rupture, make two single fiber butterfly optical cables disconnected from each other; Two single fiber butterfly optical cables Matching installation one fibre-optical splice respectively can be made easily by the existing mode of connection.
Described every bar single fiber butterfly optical cable comprises sheath 1 and the optical fiber 3 that is wrapped in sheath and two reinforcements 4; Described fiber arrangement is in the center of sheath, and reinforcement is then arranged in the both sides (left and right directions in figure) of optical fiber; Described reinforcement is that steel wire or FRP increase part and described sheath adopts low-smoke halogen-free flame retardant material or Polyvinylchloride material.Article four, the axis arranged of reinforcement is positioned in the symmetrical center line of optical cable xsect at same plane, thus obtains the Access Network butterfly leading in cable of flat.The sheath two sides (upper and lower surface in figure) of every bar single fiber butterfly optical cable is shaped with an axially extended side groove 5, and this side groove is parallel to each other with drop-center and have identical shape of cross section; Exerted oneself with different directions in the sheath both sides (both sides of side groove) of every bar single fiber butterfly optical cable, the line direction (in figure shown in B) along two side grooves in sheath just can be forced to rupture, thus tear the sheath both wings of every bar single fiber butterfly optical cable, and the optical fiber being positioned at sheath center will be separated.
The structure of described single fiber butterfly optical cable is similar to the structure of existing butterfly optical cable, and its difference part is only that an optical fiber is only arranged in the inside of single fiber butterfly optical cable, so just can improve the utilization factor of optical fiber, avoid causing unnecessary waste.
Claims (5)
