However, in practical use cases, the optical cable is often required to face a complicated environment. The most common is the tangential action of strong wind power faced by the empty-hung optical cable, and the tangential wind power is not even, so that the up-down wind power difference is generated, and the optical cable is twisted. Under normal conditions, the optical cable is slightly twisted and cannot be damaged, but once the wind force is too strong, the optical cable is twisted and twisted at a larger angle, the optical fiber wires in the optical cable are also twisted and twisted, and the optical fiber wires are twisted and twisted mutually or the outer layer is twisted and torn, so that the optical cable is damaged.

a sheath layer 100, an anti-torsion layer 200 and an inner core wire 300 which are arranged from outside to inside;
the inner core wire 300 comprises a central optical fiber wire 301, the optical fiber wire 301 is externally coated with a bundle tube 302 to form the inner core wire 300, and the optical fiber wire 301 is a single-mode optical fiber or a multi-mode optical fiber or an optical fiber bundle;
the anti-torsion layer 200 comprises an inner fixing layer 201, a middle buffer layer 202 and an outer torsion layer 203, the inner fixing layer 201 is wrapped outside the inner core wire 300, the middle buffer layer 202 is loosely sleeved outside the inner fixing layer 201, a plurality of scattered torsion buffer structures 400 are circumferentially arranged between the inner fixing layer 201 and the middle buffer layer 202, each torsion buffer structure 400 is composed of an outer buffer block 402 and an inner buffer block 401, the outer buffer blocks 402 are fixedly connected to the inner surface of the middle buffer layer 202, and the inner buffer blocks 401 are fixedly connected to the outer surface of the inner fixing layer 201;
as shown in fig. 2, the outer buffer block 402 and the inner buffer block 401 are obliquely abutted, the radial section of the abutted inclined plane and the radial direction of the optical cable form an oblique angle, and the oblique angle is 40-50 degrees;
the outer torsion layer 203 is loosely sleeved outside the middle buffer layer 202, a plurality of scattered torsion blocking structures 500 are circumferentially arranged between the outer torsion layer 203 and the middle buffer layer 202, each torsion blocking structure 500 is composed of an outer blocking block 501 and an inner blocking block 502, the outer blocking block 501 is fixedly connected to the inner surface of the outer torsion layer 203, and the inner blocking block 502 is fixedly connected to the outer surface of the middle buffer layer 202;
as shown in fig. 3, the outer blocking block 501 and the inner blocking block 502 are obliquely abutted, the radial cross section of the abutting inclined plane forms an oblique angle with the radial direction of the optical cable, the oblique angle is 40-50 degrees, and in the same radial cross section, the abutting inclined planes of the outer blocking block 501 and the inner blocking block 502 are obliquely intersected with the abutting inclined planes of the outer buffer block 402 and the inner buffer block 401, and the abutting inclined planes are not parallel to each other;
the abutting surfaces of the internal blocking blocks 502 on the middle buffer layer 202 face the same circumferential direction, the abutting surfaces of the external buffer blocks 402 face the same circumferential direction, and the abutting surfaces of the internal blocking blocks 502 and the external buffer blocks 402 face the same direction;
the sheath layer 100 is coated on the outer surface of the outer torque layer 203.
Under the cooperation of the above-mentioned structure,
as shown in fig. 4, when the sheath layer 100 is subjected to a circumferential acting force to cause the sheath layer 100 to twist, the sheath layer 100 directly acts on the outer torsion layer 203, so that the outer torsion layer 203 twists along the circumferential direction, and due to the dispersed arrangement of the torsion blocking structure 500, all abutting surfaces of the inner blocking blocks 502 on the middle buffer layer 202 face the same circumferential direction, so that when the outer torsion layer 203 generates a circumferential guiding force towards the inner centering buffer layer 202, only a guiding force in one direction is generated, for example, in this embodiment, when only the outer torsion layer 203 clockwise forms a circumferential rotation guiding force along the a direction, a guiding force can be formed towards the inner centering buffer layer 202, and when the outer torsion layer 203 anticlockwise rotates along the b direction, the outer blocking blocks 501 on the inner surface of the outer torsion layer 203 are actually separated from the inner blocking blocks 502 on the outer surface of the middle buffer layer 202, and a guiding force cannot be formed, so as to realize the blocking of the torsion;
and well buffer layer 202 receive the circumference of outer torsion layer 203 and lead the effect under force, because the butt surface of the interior buffer layer 202 inside and outside internal resistance piece 502 is opposite with the butt surface orientation of outer buffer block 402, well buffer layer 202 actually can make torsion buffer structure 400's outer buffer block 402 and interior buffer block 401 separate when twisting in circumference, can't further realize inside circumference and lead the force, in order to ensure that optic fibre line 301 can not receive the effect of circumference distortion, especially can avoid many optic fibre lines 301 intertwine distortion in the multicore cable, in addition, can make the whole very excellent antitorque effect that produces of optic cable.
Further, in the above-mentioned case,
the radial sections of the outer blocking block 501, the inner blocking block 502, the outer buffer block 402 and the inner buffer block 401 are all semicircular or quasi-semicircular;
both in this embodiment as shown in fig. 2 and 3 are quasi-semi-circular;
the outer blocking block 501, the inner blocking block 502, the outer buffer block 402 and the inner buffer block 401 which are in the shape structure are matched with the torsion blocking structure 500 and the torsion buffer structure 400, so that when the torsion structure is subjected to an excessive external force, the external force can be further absorbed through deformation, and the conduction of the internal circumferential acting force is reduced.
