In this application, 4 optical fiber unit are pre-buried in 1 inner wall of sheath along sheath length direction respectively, optical fiber unit includes optic fibre 5 and pine sleeve pipe 4, and many optic fibre 5 set up respectively in pine sleeve pipe 4, have promoted communication transmission's performance. The loose tube 4 is filled with fiber paste, and the optical fiber 5 is waterproof and hydrogen evolution resistant through the fiber paste.
4 optical fiber unit annular array distribute around through-hole 3, be provided with the circular arc groove 2 that is located between 1 excircle of optical fiber unit and sheath in the sheath 1, circular arc groove 2 extends along 1 length direction of sheath, further reduces the dead weight, and in this embodiment, circular arc groove 2 corresponds the same with the optical fiber unit, and circular arc groove 2 carries out elastic deformation when sheath 1 receives the extrusion force, together with through-hole 3, carries out the buffering of pressure, reduces the damage of optical fiber unit.
In this embodiment, the arc grooves 2 are concentric with the through holes 3, and the arc grooves 2 are uniformly distributed and can bear the extrusion force in multiple directions.
Example 2:
as shown in fig. 2, on the basis of embodiment 1, a central reinforcing core 6 is disposed in the through hole 3, so as to improve the tensile property of the sheath 1, and in this embodiment, the central reinforcing core 6 is made of steel wire, so that the structural strength is high, and the tensile effect is good.
The above description is only for the preferred embodiment of the present invention, and for those skilled in the art, there are variations on the detailed description and the application scope according to the idea of the present invention, and the content of the description should not be construed as a limitation to the present invention.
