Abstract
The utility model discloses the double Loose tube of a kind of central tubular can branching type ribbon optical fiber cable, be made up of the Loose tube of two different colours, the reinforcement of Parallel Symmetric and oversheath, described Loose tube is made up of the colored optical fiber of different colours, fine cream, PBT sleeve pipe；Described reinforcement can be FRP or steel wire；Described oversheath can be LSZH oversheath or PE oversheath.The double Loose tube of described central tubular can branching type ribbon optical fiber cable be the center becoming 45 degree of overturning angles to be placed in cable the two of different colours Loose tube with special die by special extrusion apparatus, reinforcement is symmetrically placed in both sides, outer layer extrudes one layer of flat oversheath, and descend both sides to form a symmetrical V-type stripping groove thereon, it is easy to stripping sheath.Its production technology is simple, is made up of double Loose tube, easily branched, and external diameter is little, low cost.
Description
Technical field
This utility model relates to the double Loose tube of communications optical cable technical field, specifically central tubular can branching type ribbon optical fiber cable.
Background technology
Central-beam tube type fiber optic cable typically accomplishes 12 cores at present, as accomplished more large core number, needs to tie up optical fiber and be filled in a Loose tube, produces equipment configuration high, complex process, and can not branch；If it is stranded that the double Loose tube of use need to carry out stranding, increasing production process, and external diameter is big, cost is high.
Summary of the invention
The technical problems to be solved in the utility model be to provide the double Loose tube of a kind of central tubular can branching type ribbon optical fiber cable, production technology is simple, is made up of double Loose tube, easily branched, and external diameter is little, low cost.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
The double Loose tube of a kind of central tubular can branching type ribbon optical fiber cable, be made up of the Loose tube of two different colours, the reinforcement of Parallel Symmetric and oversheath, described Loose tube is made up of the colored optical fiber of different colours, fine cream, PBT sleeve pipe；Described reinforcement can be FRP or steel wire；Described oversheath can be LSZH oversheath or PE oversheath.
Further, described Loose tube is optical fiber and fine cream to be filled in the PBT sleeve pipe of extrusion moulding by special production equipment, and forms rational excess fiber length.Loose tube color can be different, to show differentiation.
The double Loose tube of described central tubular can branching type ribbon optical fiber cable be the center becoming 45 degree of overturning angles to be placed in cable the two of different colours Loose tube with special die by special extrusion apparatus, reinforcement is symmetrically placed in both sides, outer layer extrudes one layer of flat oversheath, and descend both sides to form a symmetrical V-type stripping groove thereon, it is easy to stripping sheath.
The beneficial effects of the utility model are:
This utility model production technology is simple, has that core number is big, external diameter is little, low cost, branch the advantage such as can lay, can be applicable to indoor and outdoor and introduce.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is that the double Loose tube of this utility model central tubular can branching type ribbon optical fiber cable structural representation.
Fig. 2 is this utility model Loose tube structural representation.
In figure: 1, Loose tube, 2, reinforcement, 3, oversheath, 4, optical fiber, 5, fine cream, 6, PTB sleeve pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but the multitude of different ways that this utility model can be defined by the claims and cover is implemented.
As shown in Figure 1, the double Loose tube of the open a kind of central tubular of this utility model can branching type ribbon optical fiber cable, being added oversheath 3 by the reinforcement 2 of the Loose tube 1 of two different colours, Parallel Symmetric to form, described Loose tube 1 is made up of the colored optical fiber 4 of different colours, fine cream 5, PBT sleeve pipe 6；Described reinforcement 2 can be FRP or steel wire；Described oversheath 3 can be LSZH oversheath or PE oversheath.
As in figure 2 it is shown, described Loose tube 1 is optical fiber 4 and fine cream 5 to be filled in the PBT sleeve pipe 6 of extrusion moulding by special production equipment, and form rational excess fiber length.Two Loose tube 1 colors are different, to show differentiation.
The double Loose tube of central tubular can branching type ribbon optical fiber cable be to become 45 degree of overturning angles to be placed in the center of cable the Loose tube 1 of two different colours by special extrusion apparatus with special die, reinforcement 2 is symmetrically placed in both sides, outer layer extrudes one layer of flat oversheath 3, and descend both sides to form a symmetrical V-type stripping groove thereon, it is easy to stripping sheath.
Above-described this utility model embodiment, is not intended that the restriction to this utility model protection domain.Any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in claims of the present utility model.
