The utility model discloses a light modular construction is reasonable, and application scope is wide, and easily discernment is convenient for lay, has characteristics such as high strength.
Description
Technical field
This utility model belongs to optical fiber cable technical field, and in particular to a kind of air-blowing high-strength micro vitta optical fiber list
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 be identified on its surface because size is little using printing mode, therefore be only capable of by using not
Make a distinction with the sheath of color, mode is single；Further, since result in traditional air-blowing optical fiber list without reinforcement material in structure
First mechanical protection ability is poor.
Utility model content
Technical problem to be solved in the utility model be to provide it is a kind of with very strong survivability, it is readily identified and
It is easy to the air-blowing high-strength micro vitta optical fiber unit for laying.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of air-blowing high-strength micro vitta optical fiber unit, including some optical fiber, external protection, inner protective layer and in
Protective layer；The some optical fiber are in a row neatly closely arranged, and the inner protective layer is using ultralow modulus resin material and leads to
Cross the mode of curing molding by some optical fiber being coated on inside it tightly；The middle protective layer be high modulus resin material simultaneously
Jing ultraviolet light polymerizations are coated on outside inner protective layer；External protection is nylon or high-density polyethylene material, the external protection
One or more vitta is longitudinally embedded in surface, the color of the vitta is other any face in addition to external protection self color
The surface of color, the external protection and vitta is laciniation；It is uniformly embedded between the external protection and middle protective layer
The many reinforcements by made by high strength glass fiber or aramid fiber yarn.
The utility model has the advantages that：
1）The design of vitta, improves the degree easy to identify of fiber unit, facilitates engineering construction attendant to optical fiber
Unit makes a distinction；
2）Optical fiber is in a row neatly compactly arranged, and reduces the overall dimensions of fiber unit, at utmost presents miniature air-blowing
The size advantage of fiber unit；
3）Inner protective layer using ultralow modulus resin by optical fiber curing molding, wherein optical fiber is served effectively buffering and
First protective effect；
4）Middle protective layer is high modulus resin material, has higher intensity Jing after ultraviolet light polymerization, and fiber unit is risen
To the effect of effective mechanical protection；
5）The laciniation design on external protection and vitta surface, reduces the contact surface of fiber unit and air-blowing micro-pipe
Product, while increased the contact area of fiber unit and air-flow, improves air-blowing performance so that disposable air-blown installation distance is remote
Traditional air-blowing fiber unit is far surmounted；
6）It is firmly bonded between the three-layer protection layer of fiber unit, close structure, forms organic whole, and material therefor is equal
It is strong with anti-electromagnetic interference capability for non-metallic material, the features such as anti-lightning strike.
Description of the drawings
This utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is structural representation of the present utility model.
Wherein, 1, vitta, 2, inner protective layer, 3 optical fiber, 4, middle protective layer, 5, reinforcement, 6, external protection.
Specific embodiment：
As shown in figure 1, a kind of air-blowing high-strength micro vitta optical fiber unit, including some optical fiber 3, external protection 6,
Inner protective layer 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 using ultralow modulus resin material and by curing molding by the way of by some optical fiber 3 tightly
It is coated on inside it, reaches the purpose that buffering and first protective effect are played to optical fiber 3.
Middle protective layer 4 is that high modulus resin material and Jing ultraviolet light polymerizations are coated on outside inner protective layer 2, further enhances light
The mechanical performance of fine unit.
External protection 6 is nylon or high-density polyethylene material, one is longitudinally embedded in the surface of external protection 6 and eradicates outer guarantor
The vitta 1 of other random colors outside sheath self color, improves the degree easy to identify of fiber unit, facilitates engineering construction
Attendant makes a distinction to fiber unit.
The surface of external protection 6 and vitta 1 is laciniation, reduces the contact surface of fiber unit and air-blowing micro-pipe
Product, while increased the contact area of fiber unit and air-flow, improves air-blowing performance so that disposable air-blown installation distance is remote
Traditional air-blowing fiber unit is far surmounted.
At least four are uniformly embedded between external protection 6 and middle protective layer 4 by high strength glass fiber or aramid fiber yarn system
Into reinforcement 5, further lift the mechanical performances such as tension, resistance to compression and shock resistance of fiber unit.
It is firmly bonded between the three-layer protection layer of fiber unit of the present utility model, close structure, forms organic whole, and
Material therefor is non-metallic material so that fiber unit has anti-electromagnetic interference capability strong, the advantages of anti-lightning strike.
