Method brings the defect that service life is short, is easy infiltration, protects optical fibre capacity weak to be improved, and allows main part using more preferable
Safeguard structure, operation of the present invention is easy, and protective performance is excellent.
Optionally, the sharp edge is made of two folded blocks, and two folded block intersections are at an acute angle.Sharp edge is made of two folded blocks,
Two folded block intersections are at an acute angle, and the area that sharp edge is contacted with main part is smaller, more labor-saving when removing reinforcing member and main part.
Optionally, waterproof pressure layer is covered on outer lower face surface on the main part.Waterproof pressure layer further improves main part
To the protective value of optical fiber.
Optionally, the waterproof pressure layer takes PVC material.
Optionally, the adhesion layer is glue.
Optionally, the fiber outer surface is also enclosed with protecting film.
Optionally, the protecting film uses the lighttight coating of waterproof.For the design using foaming layer (white), use
The lighttight coating of waterproof further improves the reflecting properties of optical fiber, reduces the optical fiber bring loss of signal reflected, goes forward side by side
One step improves waterproof performance.
Compared with prior art, the technical program has the advantage that
The present invention has the reinforcing member of sharp edge, extension by setting, and the radial height of main part is less than or equal to reinforcing member
Radial height so that optical cable more power when by vertical direction pressure are shared on reinforcing member, so that reinforcing member is pressure-resistant
Property is more preferable.Sharp edge is connected by adhesion layer with main part simultaneously, so that sharp edge is easier to separate with main part, and main part is formed after separation
Two opposite grooves, convenient for removing again, optical fiber can be obtained by further tearing foaming layer, by the side that secondary removing is arranged
Method changes optical fiber ablation direction, and the thickness for improving main part substantially improves the protective performance in fiber perpendicular direction, and adopts
With the foaming layer filled with the nitrogen for being more than or equal to 1.5 standard atmospheric pressures, the performance that prevents water penetration of optical fiber, this hair are further improved
It is bright that a stripping means perpendicular to cable surface is made to bring service life is short, be easy infiltration, protection optical fibre capacity is weak to lack
It falls into and is improved, allow main part using better safeguard structure, operation of the present invention is easy, and protective performance is excellent.
In addition, sharp edge is made of two folded blocks, two folded block intersections are at an acute angle, and the area that sharp edge is contacted with main part is smaller,
It is more labor-saving when removing reinforcing member and main part.Waterproof pressure layer further improves main part to the protective value of optical fiber.For adopting
With the design of foaming layer (white), further improve the reflecting properties of optical fiber using the lighttight coating of waterproof, reduction reflects
Optical fiber bring loss of signal, and further improve waterproof performance.
