Profit, security performance, the requirement of adaptive capacity to environment are higher and higher.
In optical access network practical application scene, an access optical cable need to be carried out to midway and put in a skylight operation (also known as
The lower fine operation in midway), there are following drawbacks in design for original cable configuration：
1, optical cable inconvenience carries out stripping and the operation that puts in a skylight halfway；
2, it makes troubles to construction, causes the construction time long, increase difficulty of construction and expense；
3, it makes troubles to maintenance, causes maintenance time long, increase maintenance difficulties and expense.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of easy-peel tightly packaged fiber tail optical fiber, easily
The operation consequently facilitating midway of optical fiber is put in a skylight in stripping is conducive to construction and safeguards.
The technical solution of the utility model is as follows：A kind of easy-peel tightly packaged fiber tail optical fiber, including inner sheath, be sheathed on it is described in
The oversheath of sheath periphery is set to fiber unit and be set to described that the inner sheath hollow portion is made of two optical fiber
The section of the reinforcer of fiber unit both sides, the inner sheath and oversheath is ellipse, the inner sheath, oversheath it is upper
Lower both sides are equipped with the V-shaped groove in section, and the axis of the vee-cut is interlaced and is located at inner sheath and oversheath section
The both sides of face short axle, are equipped with that tool is not viscous and the separating layer of greasy property between the oversheath and inner sheath, the separating layer by
Constituted by the filling glue of matrix of synthetic oil, be embedded with tear rope in the levels of the separating layer respectively, the tear rope with
Vee-cut on oversheath is correspondingly arranged.
Further, two optical fiber is in a row along the axial alignment of inner sheath major cross-sectional axis, and the two of the inner sheath
The slot tip position of a vee-cut is respectively toward to the central axes of the file leader and last person's optical fiber of the optical fiber row of axial alignment.
Further, waterproof insulation material is filled between the inner sheath and fiber unit, reinforcer.
Further, the optical fiber is made of fiber core, fibre cladding and optical fiber coating.
Compared with the existing technology, the beneficial effects of the utility model are：Two V are respectively set in the outer wall of interior oversheath
Shape groove is equipped with not viscous and greasy property the separating layer of tool between oversheath and inner sheath, difference is embedding in the levels of separating layer
Equipped with tear rope, facilitate carry out cable put in a skylight operation, using operation and maintenance, and the axis of two vee-cuts is not at one
On axis, but interlaced arrangement, and the slot tip position of two vee-cuts is respectively toward to optical fiber row not instead of against an optical fiber
File leader and last person's optical fiber central axes, when interior oversheath being made to be torn along two vee-cuts, whole cable cores can be exposed,
To achieve the effect that stripping is rapid, reduces the fiber cable laying time.The time is not only saved in this way, but also avoids shelling from sheath again
It may be scratched caused by optical fiber surface when from optical fiber.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Specific implementation mode
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Referring to Fig. 1, a kind of easy-peel tightly packaged fiber tail optical fiber of the utility model, including inner sheath 1, it is sheathed on the inner sheath 1
The oversheath 2 of periphery is set to fiber unit 3 and be set to fiber unit 3 that 1 hollow portion of inner sheath is made of two optical fiber
The reinforcer 4 of both sides, the optical fiber are made of fiber core 31, fibre cladding 32 and optical fiber coating 33, and reinforcer 4 is set to
The both sides of fiber unit 3 can make cable have a tensile property, and the section of inner sheath 1 and oversheath 2 is ellipse, inner sheath 1,
The both sides up and down of oversheath 2 are equipped with the V-shaped groove 5 in section, and the axis of vee-cut 5 is interlaced and is located at inner sheath 1
With the both sides of 2 cross-section minor axis of oversheath, not viscous and greasy property the separating layer 6 of tool is equipped between oversheath 2 and inner sheath 1, point
Absciss layer 6 is embedded with tear rope 7, tear rope 7 respectively by being constituted by the filling glue of matrix of synthetic oil in the levels of separating layer 6
It is correspondingly arranged with the vee-cut 5 on oversheath 2.First one week is cut on oversheath 2 with cutter, then when putting in a skylight operation
It is first that tear rope 7 is exposed using the 5 laborsaving stripping oversheath 2 of vee-cut on oversheath 2, then force in the tear rope 7 drawing
Over sheath 2, expose inner sheath 1, then scratch inner sheath 1 with cutter again, further utilize inner sheath 1 on 5 province of vee-cut
Power peels off one section of inner sheath 1, to expose the optical fiber inside inner sheath 1.
