Examples
A mating optical cable as shown in fig. 1, comprising in particular:
the optical fiber cable comprises an outer sheath 100, an inner sheath 200 and a bundle pipe 300 which are sequentially arranged from outside to inside, wherein the outer sheath 100 is arranged outside the inner sheath 200, the inner sheath 200 is arranged outside the bundle pipe 300, and a plurality of optical fiber wires 400 arranged along the axial direction of the optical fiber cable are arranged in the bundle pipe 300;
the optical fiber line 400 is a single-mode optical fiber or a multi-mode optical fiber or an optical fiber bundle;
the outer sheath 100 and the inner sheath 200 are fixed in a contact manner by adopting the protrusions arranged in a dense array form, and both are made of materials with certain elasticity, for example, in the embodiment, the outer sheath 100 and the inner sheath 200 are made of elastic PVC materials;
in particular, the method comprises the following steps of,
as shown in fig. 1 and fig. 2, the inner surface of the outer sheath 100 is provided with convex structures 101, the convex structures 101 are uniformly arranged on the inner surface of the outer sheath 100 along the circumferential direction of the radial cross section of the optical cable, the convex structures 101 are protruded inwards along the radial direction of the optical cable, adjacent convex structures 101 are separated from each other and do not contact with each other, and an outer groove 1011 is formed between adjacent convex structures 101;
the width of the outer groove 1011 on the radial section of the optical cable is larger than that of the convex structure 101 on the radial section of the optical cable;
the outer surface of the inner sheath 200 is provided with inner convex structures 201, the inner convex structures 201 are uniformly arranged on the outer surface of the inner sheath 200 along the circumferential direction of the radial cross section of the optical cable, the adjacent inner convex structures 201 are separated from each other and do not contact with each other, an inner groove 2011 is formed between the adjacent inner convex structures 201, and the convex direction of the inner convex structures 201 and the radial direction of the optical cable are arranged in an oblique angle;
the width of the inner convex structure 201 on the radial section of the optical cable is equal to that of the outer groove 1011 on the radial section of the optical cable, and the width of the inner groove 2011 on the radial section of the optical cable is equal to that of the outer convex structure 101 on the radial section of the optical cable;
the convex structure 101 on the inner surface of the outer sheath 100 is obliquely meshed with the convex structure 201 on the outer surface of the inner sheath 200;
as shown in fig. 3, in cooperation with the above-mentioned structures, the inclined side wall of the inner groove 2011 of the inner sheath 200 can abut against and support the end of the outer convex structure 101 of the outer sheath 100 along the a direction, so as to form a supporting force along the radial direction of the optical cable, and at the same time, the elastic support formed by the engagement between the inner and outer sheaths can help to recover the roundness of the optical cable;
in addition, when the external force F1 acts on the optical cable, the optical cable of the present invention can form a strong compressive effect in all directions and multiple angles, because when the external force acts on the optical cable, the inner groove 2011 can form a deformation guide along the direction b in fig. 3 for the outer convex structure 101, and under the condition that the outer convex structure 101, the inner convex structure 201, the outer groove 1011, and the inner groove 2011 are all arranged along the radial direction of the optical cable, the outer convex structure 101 can move directly inward along the radial direction of the optical cable, and the external force is weakened by means of extrusion deformation and friction buffering, but the actual external force still forms conduction along the radial direction of the optical cable, so that in order to further weaken the radial force, the present invention makes the concave direction of the inner groove 2011 and the radial direction of the optical cable in an oblique crossing state by means of obliquely arranging the inner convex structure 201;
under the exogenic action, evagination structure 101 inserts along inner grove 2011 slant, has changed the actual power direction of leading, increases simultaneously evagination structure 101 and inner grove 2011's frictional force, and also can drive evagination structure 101 and warp when interior bulge 201 inserts outer groove 1011, forms multiple deformation and friction buffering effect, has blocked the radial power of leading of optical cable to a very big degree for the optical cable possesses excellent compressive property.
Further, in the above-mentioned case,

as in the present embodiment, the outer crescent cavities 102 are uniformly arranged in six in the circumferential direction of the optical cable, and the inner crescent cavities 202 are uniformly arranged in six in the circumferential direction of the optical cable;
the circumferential wrapping angle of the outer crescent cavity 102 on the cross section of the optical cable is 30-45 degrees, and the circumferential wrapping angle of the inner crescent cavity 202 on the cross section of the optical cable is 35-50 degrees;
the inner crescent cavities 202 and the outer crescent cavities 102 are uniformly and alternately arranged in the circumferential direction;
the optical cable can be effectively and circumferentially completely coated by the outer crescent cavity 102 and the inner crescent cavity 202 with the coating angle and the alternate arrangement mode, so that the total coating angle of the outer crescent cavity 102 and the inner crescent cavity 202 is more than or equal to 390 degrees (more than 360 degrees of one week), the omnidirectional compression resistance of the optical cable is improved, and the optical fiber 400 in the optical cable can be well protected by the buffer edges of the outer crescent cavity 102 and the inner crescent cavity 202;
if the total wrapping angle is set to be 360-370 degrees, it is found in a specific use process that when the external force which just passes through the boundary of the outer crescent cavity 102 and the inner crescent cavity 202 shown in fig. 1 acts, the outer crescent cavity 102 and the inner crescent cavity 202 cannot generate a good deformation buffering effect;
if the circumferential coating angle of the outer crescent cavity 102 and the inner crescent cavity 202 is too large, a similar conventional annular structure is easily formed, which may cause the roundness support performance of the optical cable to be weakened, and the high roundness characteristic of the optical cable cannot be effectively maintained, so that the total coating angle of the outer crescent cavity 102 and the inner crescent cavity 202 should be further limited to be less than or equal to 510 degrees;
the maximum circumferential wrap angle of the inner crescent cavity 202 is greater than the maximum circumferential wrap angle of the outer crescent cavity 102, because the inner crescent cavity 202 is close to the inside of the optical cable structure, the structural compactness is higher;
the outer wall surface of the outer crescent cavity 102 is provided with an outer reinforcing piece 103 in a fitting manner, and the inner wall surface of the inner crescent cavity 202 is provided with an inner reinforcing piece 203 in a fitting manner;
the arrangement of the crescent cavity and the reinforcing piece can further strengthen the pressure resistance of the optical cable;
the inner reinforcement 203 and the outer reinforcement 103 are made of non-metallic materials, such as FRP, GFRP or elastic materials, including elastic PE, PVC or TPU.
The inner crescent cavity 202 and the inner reinforcement member 203 are mainly used for further improving the radial buffering effect of external acting force, so that the inner sheath 200 has stronger deformation buffering capacity;
and the arrangement of the outer crescent cavity 102 and the outer reinforcing member 103 can effectively prevent the problem of permanent deformation of the optical cable caused by the fact that the outer acting force is too large and the outer convex structure 101 is embedded deeply, so that the optical cable is easier to recover after being deformed by stress.
