Background technology
With the development of optical communications industry, Metropolitan Area Network (MAN) pipeline resource seems further nervous, thus air-blowing minisize optical cable application
And give birth to, using the Loose tube and single layer PE sheaths of pipe with small pipe diameter, the laying density of pipeline optical fiber is can effectively improve, but due to PE
Jacket wall thickness, under pipeline environment, ant proof performance is weaker；Secondly, rub resistance, pressure-resistant performance are weaker, will certainly influence it
Air-blowing performance.
Invention content
In view of this, the invention is intended to overcome above-mentioned defect existing in the prior art, a kind of novel center is proposed
The miniature termite proof cable of beam tube type air-blowing.
In order to achieve the above objectives, the technical solution of the invention is realized in：
A kind of novel miniature termite proof cable of central beam tube type air-blowing includes several light of Loose tube and its inside cladding
Fibre is filled with material water-proof material between each optical fiber；Be coated with sheath and outer jacket successively on the outside of the Loose tube, sheath with
Functional unit is equipped between Loose tube.
Further, the sheath uses double-layer structure, including the polyethylene inner layer of extrusion forming and its outside simultaneously
Nylon outer layer.
Further, the outer jacket uses double-layer structure, including the polyethylene inner layer of extrusion forming and its outside simultaneously
Nylon outer layer.
Further, the material water-proof material selects fiber paste, water blocking yarn or water-proofing powder.
Further, the sheath thickness is more than outer jacket thickness.
Further, the functional unit includes aramid layers.
Further, the functional unit includes tear rope.
Compared with the existing technology, the invention has the advantage that：
The invention stable structure is reliable, sheath and outer jacket is arranged simultaneously on the outside of Loose tube, the two is with cooperation
With playing the role of jointly antitorque impact-resistant, effectively play protective action to internal optical fiber.Mouse bite preventing ability is strong, antifriction
Wiping, pressure-resistant performance are all relatively good, and air-blowing is had excellent performance.

With reference to embodiment come the present invention will be described in detail create.
A kind of novel miniature termite proof cable of central beam tube type air-blowing, as shown in Figure 1, being coated including Loose tube 3 and its inside
Several optical fiber 1, material water-proof material 2 is filled between each optical fiber 1；The outside of the Loose tube 3 is coated with sheath 5 and outer successively
Sheath 6 is equipped with functional unit 4 between sheath 5 and Loose tube 3.Each optical fiber is uniformly separated by material water-proof material, mutually without dry
It disturbs, stable signal transmission is reliable.
Above-mentioned sheath 5 uses double-layer structure, including simultaneously outside the polyethylene inner layer of extrusion forming and its nylon in outside
Layer.Above-mentioned outer jacket 6 uses double-layer structure, including the polyethylene inner layer of extrusion forming and its nylon outer layer in outside simultaneously.
Sheath, outer jacket are all made of double-layer structure, and structural strength is high, and anti-pressure and abrasion-proof is good, especially outside sheath
Outer jacket is directly arranged in side, also, outer jacket and sheath are respectively double-layer structure, is respectively outside polyethylene inner layer and nylon
Layer fits closely, the tension anti-twisting property benefit that is all preferable, also, designing in this way of outer jacket itself and sheath itself
It is during actual laying and use, when optical cable is by torsion force, to allow outer jacket to have relative to sheath certain
Torsion or deformation effectively weaken and are unlikely to make sheath or even its internal optical fiber gross distortion, more added with protection
Optical cable.In general, above-mentioned sheath thickness is more than outer jacket thickness, in actual use, outer jacket wearability is good, also, in this way
Structure design, exactly in order to allow outer jacket to have certain torsional deflection amount relative to sheath, and thicker sheath energy
Enough play the role of extraordinary shock resistance, anti-extrusion plays good protective action to internal cable core.
In an alternative embodiment, capsaicine can be added between sheath and outer jacket, it can be significantly more efficient
Prevent damaged by rats.Furthermore it is also possible to which shielded layer is arranged between sheath and Loose tube, shielded layer is close to Loose tube setting, can
Splendid shielding Anti-Jamming is played, and does not interfere with stripping sheath.
Above-mentioned material water-proof material selects fiber paste, water blocking yarn or water-proofing powder, can effectively play waterproof action, permanent protection
Optical fiber.
Above-mentioned functional unit includes aramid layers, using functional unit, can effectively play the role of mouse bite preventing, improve
Impact resistance, meanwhile, benefit is brought to the structural stability raising of optical cable.In addition, functional unit can also include tear rope,
Can when necessary, by tear rope tear layer structure, ensure optical cable smoothly lay or special operation condition under answer
With.
The invention stable structure is reliable, sheath and outer jacket is arranged simultaneously on the outside of Loose tube, the two is with cooperation
With playing the role of jointly antitorque impact-resistant, effectively play protective action to internal optical fiber.Mouse bite preventing ability is strong, antifriction
Wiping, pressure-resistant performance are all relatively good, and air-blowing is had excellent performance.
The foregoing is merely the preferred embodiments of the invention, are not intended to limit the invention creation, all at this
Within the spirit and principle of innovation and creation, any modification, equivalent replacement, improvement and so on should be included in the invention
Protection domain within.
