Abstract
The utility model discloses a miniature vitta optical cable of high strength central tube for air -blowing, its characterized in that: including light unit, interior protective layer, well protective layer and external coating, the light unit is arranged in the interior protective layer, the light unit comprises a plurality of optic fibre and the oil filler of paste, including the well protective layer cladding outside the protective layer, the surface of well protective layer vertically imbeds one or many vittas, the colour of vitta is other the arbitrary colours except that well protective layer self colour, the reinforcement that many causes high strength glass fiber material was made still evenly imbeds in the well sheath, external coating is the transparence cladding outside well protective layer, external coating's thickness is less than 0.5mm. 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 is related to a kind of optical cable, and in particular to a kind of air-blowing miniature vitta optical cable of high intensity central tubular,
Belong to optical fiber cable technical field.
Background technology
With the development of " broadband China " implementation and Fibre Optical Communication Technology, operator continues to increase fiber optic network and builds
If the input of aspect, the new networking climax of a wheel has been started.China's soliton communication also obtain good development machine
Meet, the demand of optical fiber cable is significantly incremented by year by year, from the point of view of development in recent years, optical cable present size miniaturization, it is high-strength
Degree protection, easy Division identification, can the trend destroyed of anti-extraneous bioturbation.
Traditional central tubular air-blowing minisize optical cable structure is usually two-layer protection outside optical fiber（PBT Loose tubes and PE are protected
Set）, optical cable global sections are rounded, because material is selected and structure is single, cause micro optical cable exist in the application low intensity,
Not easy to identify the shortcomings of.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of high intensity, the miniature color of readily identified central tubular
Bar optical cable.
To solve above-mentioned technical problem, the technical solution adopted in the utility model is：
A kind of air-blowing miniature vitta optical cable of high intensity central tubular, including light unit, inner protective layer, middle protective layer and outer
Protective layer, the light unit is placed in inner protective layer, and the light unit is made up of some optical fiber and paste oiliness implant, institute
State protective layer to be coated on outside inner protective layer, the surface longitudinal of the middle protective layer is embedded in one or more vitta, the vitta
Color be other random colors outside a good appetite suddenly appearing in a serious disease protective layer self color, is also uniformly embedded into many by high intensity in the middle sheath
Reinforcement made by glass fiber material, the transparent shape of the external protection is coated on outside middle protective layer, the external protection
Thickness is less than 0.5mm.
Further, the inner protective layer is made up of high-strength PC engineering plastics.
Further, the middle protective layer is made up of PP or PE materials.
Further, the reinforcement at least four.
Further, the surface of the external protection is laciniation.
The utility model has the advantages that：
1）Inner protective layer adopts high-strength PC engineering plastics so that optical cable has high lateral pressure resistant and high impact resistance, together
When axial post-shrinkage ratio it is extremely stable, it is ensured that optical cable has the very wide resistance to ambient temperature scope of application.
2）Middle protective layer material adopts PP or PE materials, with lightweight, the advantages of flexibility is good, while in middle sheath
The many reinforcements by made by high strength glass fiber are uniformly embedded into, mechanical and physical performance and the protection against rodents of optical cable is further improved
Anti- ant destructive characteristics.Additionally, middle protective layer also longitudinally embedded in one or more different from middle protective layer intrinsic colour
Vitta, improve the degree easy to identify of optical cable, be easy to construct and keep in repair.
3）External protection is slim transparent zigzag layer, it is ensured that the vitta of middle protective layer can be recognized clearly,
Serrated appearance reduces the contact area of optical cable and air-blowing pipeline, while increased the contact area of optical cable and air-flow, carries
The high air-blowing performance of optical cable.
4）Be firmly bonded between three-layer protection layer, close structure, form organic whole, cable machinery intensity is high, storage,
It is unlikely to deform in transport and installation process.
5）The material that optical cable is adopted is non-metallic material so that optical cable has anti-electromagnetic interference capability strong, anti-lightning strike
The features such as.
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, reinforcement, 5, paste oiliness implant, 6, middle protective layer, 7,
External protection.
Specific embodiment：
As shown in figure 1, a kind of air-blowing miniature vitta optical cable of high intensity central tubular, including light unit, inner protective layer 2,
Middle protective layer 6 and external protection 7, light unit is placed in the inner protective layer 2 by made by high-strength PC engineering plastics.
Light unit is made up of some optical fiber 3 and paste oiliness implant 5, and paste oiliness implant 5 plays slow to optical fiber 3
Punching and the effect protected.
Middle protective layer 6 is coated on outside inner protective layer 2 by made by PP or PE materials, embedding in the surface longitudinal of middle protective layer 6
Enter a vitta 1, the color of vitta 1 is other random colors outside the self color of a good appetite suddenly appearing in a serious disease protective layer 6.Meanwhile, in middle sheath 6 also
Six roots of sensation reinforcement 4 by made by high strength glass fiber material is uniformly embedded into, the mechanical and physical performance of optical cable is further improved.
The transparent shape of external protection 7 is coated on outside middle protective layer 6, and the thickness of external protection 6 is less than 0.5mm.
