Description
Technical field
The invention belongs to optical fiber cable technical field, be specifically related to a kind of air-blowing high-strength micro vitta fiber unit.
Background technology
During fiber broadband networking, air-blowing fiber unit is commonly used for " last one kilometer " intelligent acess.Pass
The air-blowing fiber unit of system cannot use printing mode to be identified owing to size is little on its surface, is therefore only capable of by using not
Making a distinction with the sheath of color, mode is single；Further, since structure result in traditional air-blowing optical fiber list without reinforcement material
Unit's mechanical protection ability is poor.
Summary of the invention
The technical problem to be solved is to provide a kind of has the strongest survivability, readily identified and be easy to
The air-blowing high-strength micro vitta fiber unit laid.
For solving above-mentioned technical problem, the technical solution used in the present invention is:
A kind of air-blowing high-strength micro vitta fiber unit, including some optical fiber, external protection, inner protective layer and middle protection
Layer；Some described optical fiber are in a row neatly closely arranged, and described inner protective layer uses ultralow modulus resin material and by solid
The mode of chemical conversion type is by some optical fiber cladding tightly therein；Described middle protective layer is high modulus resin material through purple
Outer photocuring is coated on outside inner protective layer；External protection is nylon or high-density polyethylene material, the surface of described external protection
Interior longitudinally embed one or more vitta, the color of described vitta be except other random colors outside protective layer self color,
The surface of described external protection and vitta is laciniation；Many it are uniformly embedded between described external protection and middle protective layer
The reinforcement being made up of high strength glass fiber or aramid fiber yarn.
The invention have the advantage that
1) design of vitta, improves the degree easy to identify of fiber unit, facilitates engineering construction attendant to fiber unit
Make a distinction；
2) optical fiber is arranged the most neatly compactly, reduces the overall dimensions of fiber unit, at utmost presents miniature air-blowing optical fiber
The size advantage of unit；
3) inner protective layer uses ultralow modulus resin by optical fiber curing molding, and wherein optical fiber serves effective buffering and first
Pipe protection effect；
4) in, protective layer is high modulus resin material, has higher intensity, played fiber unit after ultraviolet light polymerization
The mechanical protection effect of effect；
5) the laciniation design on external protection and vitta surface, reduces the contact area of fiber unit and the micro-pipe of air-blowing,
Add the contact area of fiber unit and air-flow simultaneously, improve air-blowing performance so that disposable air-blown installation distance is far away
Surmount traditional air-blowing fiber unit；
6) it is firmly bonded between the three-layer protection layer of fiber unit, close structure, forms organic whole, and material therefor is non-
The features such as metal material, has anti-electromagnetic interference capability strong, anti-lightning strike.
Accompanying drawing explanation
With detailed description of the invention, the present invention is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Wherein, 1, vitta, 2, inner protective layer, 3 optical fiber, 4, middle protective layer, 5, reinforcement, 6, external protection.
Detailed description of the invention:
As it is shown in figure 1, a kind of air-blowing high-strength micro vitta fiber unit, including some optical fiber 3, external protection 6, interior guarantor
Sheath 2 and middle protective layer 4.
Some optical fiber in a row neatly closely arrange to reduce the overall dimensions of fiber unit.
Inner protective layer 2 use ultralow modulus resin material and by the way of curing molding by some optical fiber 3 tightly
Cladding therein, reaches optical fiber 3 plays buffering and the purpose of first protective effect.
Middle protective layer 4, for high modulus resin material and outside ultraviolet light polymerization is coated on inner protective layer 2, further enhances light
The mechanical performance of fine unit.
External protection 6 is nylon or high-density polyethylene material, longitudinally embeds an outer guarantor of elimination in the surface of external protection 6
The vitta 1 of other random colors outside sheath self color, improves the degree easy to identify of fiber unit, facilitates engineering construction
Fiber unit is made a distinction by attendant.
The surface of external protection 6 and vitta 1 is laciniation, reduces the contact surface of fiber unit and the micro-pipe of air-blowing
Long-pending, add the contact area of fiber unit and air-flow simultaneously, improve air-blowing performance so that disposable air-blown installation distance is remote
Far surmount traditional air-blowing fiber unit.
At least four it are uniformly embedded into by high strength glass fiber or aramid fiber yarn system between external protection 6 and middle protective layer 4
The reinforcement 5 become, promotes the mechanical performances such as the tension of fiber unit, resistance to compression and shock resistance further.
It is firmly bonded between the three-layer protection layer of the fiber unit of the present invention, close structure, forms organic whole, and used
Material is non-metallic material so that the advantages such as it is strong that fiber unit has anti-electromagnetic interference capability, anti-lightning strike.
