Sharply increase, fiber to the home (FTTH) turns into inevitable.Optical cable needs to be laid in cell Nei Huo buildings, and conduit resource is nervous,
Therefore lightweight in the urgent need to a kind of small volume, the integrated core number of optical fiber optical cable high substitutes common wiring optical cable.
Meanwhile, generally need to cut cable cover(ing) and remove a part for sheath when optical fiber cable is constructed, so as to allow to connect
Enter the optical fiber in sheath.The general mode for taking professional to be peeled off by hand by exfoliation tool, the operation for operator will
Ask high, careless manipulation easily damages cable core.Particularly the small optical cable of size, peels off difficulty higher.
In sum, a kind of oversheath is needed badly easily peelable, small volume, lightweight optical cable unit substitutes current wiring
Optical cable unit.
The content of the invention
For defect present in prior art, it is an object of the invention to provide it is a kind of can hand tear the optical cable unit of stripping
And preparation method thereof, oversheath is easily peelable, small volume, lightweight.
To achieve the above objectives, the present invention is adopted the technical scheme that：It is a kind of can hand tear the optical cable unit of stripping, it is including outer
Sheath, the fiber unit in oversheath, and the filling fibre cream between oversheath and the fiber unit；It is described outer
Sheath by thickness between 0.05~0.15mm, material of the elongation at break in the range of 15~30% constitute, the oversheath
0.5 is less than with the coefficient of friction between the fiber unit.
On the basis of above-mentioned technical proposal, the material is polyvinyl chloride, low smoke halogen-free flame-retardant polyolefin or modified heat
Plastic polyurethane elastomeric material.
On the basis of above-mentioned technical proposal, the fine cream of filling is distributed to shape in base oil for one or more gelling agents
Into toughness spawn.
On the basis of above-mentioned technical proposal, the fiber unit is one or more colored optical fiber.
On the basis of above-mentioned technical proposal, the colored optical fiber be single-mode fiber G.657A1, G.657A2 and G.657B3
In any one formed by coloring.
The invention also discloses it is a kind of can hand tear stripping optical cable unit manufacture method, comprise the following steps：
A, bare fibre is coloured in advance；
B, the fine cream of one layer of filling of uniform coating on colored optical fiber；
C, the material by elongation at break in the range of 15~30% add extruding machine, and one layer is extruded on the fine cream surface of filling
Thickness is that the oversheath of 0.05~0.15mm coats colored optical fiber and the fine cream of filling completely.
On the basis of above-mentioned technical proposal, the coefficient of friction between the oversheath and the fiber unit is less than 0.5.
Compared with prior art, the advantage of the invention is that：
Coefficient of friction between optical cable unit oversheath of the invention and fiber unit is less than 0.5, thus the oversheath is easy
Peeled off with cable core；Using the elastomeric material system that thickness is between 0.05~0.15mm, elongation at break is in the range of 15~30%
Into oversheath, thus the easy tear fracture of oversheath.The optical cable unit can be integrated into various wiring optical cables as light unit in the present invention,
Its oversheath it is light, thin and can hand tear stripping, therefore, not only Cable Core Number is more for the wiring optical cable being made of the optical cable unit, and
And small volume, it is lightweight, be particularly well-suited to be used in laying optical cable in cell Nei Huo buildings, effectively improve optical cable construction efficiency with
And conduit resource utilization rate.
Brief description of the drawings
Fig. 1 be the embodiment of the present invention in can hand tear stripping optical cable unit structural representation；
Fig. 2 be the embodiment of the present invention in can hand tear stripping optical cable unit preparation method schematic flow sheet.
In figure：1- oversheaths, the fine cream of 2- fillings, 3- fiber units.
Specific embodiment
The present invention is described in further detail below in conjunction with drawings and Examples.
It is shown in Figure 1, the embodiment of the present invention provide it is a kind of can hand tear the optical cable unit of stripping, including oversheath 1, be located at
Fiber unit 3 in oversheath 1, and the filling fibre cream 2 between oversheath 1 and the fiber unit 3；The oversheath
1 by thickness between 0.05~0.15mm, elastomeric material of the elongation at break in the range of 15~30% constitute, the oversheath
Coefficient of friction between 1 and the fiber unit 3 is less than 0.5.The elastomeric material is polyvinyl chloride, low-smoke non-halogen flame-retardant polyene
Hydrocarbon or modified thermoplastic polyurethane elastomeric material.The fine cream 2 of filling is distributed in base oil for one or more gelling agents
The toughness spawn of formation.The fiber unit 3 is one or more colored optical fiber.The fiber unit 3 is 1~12
Root optical fiber.The colored optical fiber be single-mode fiber G.657A1, G.657A2 and G.657B3 in any one formed by coloring.
Friction coefficient between optical cable unit oversheath 1 of the present invention and fiber unit 3 is less than 0.5, thus should
Oversheath 1 is easily peeled off with cable core；Using thickness between 0.05~0.15mm, bullet of the elongation at break in the range of 15~30%
Property material is made oversheath 1, thus the easy tear fracture of oversheath 1.The optical cable unit can be integrated into various as light unit in the present invention
In wiring optical cable, its oversheath 1 it is light, thin and can hand tear stripping, therefore, the wiring optical cable being made of the optical cable unit not only light
