The 5G network requires a large core number, high density optical cable; the skeleton-type optical cable is popular because the required optical fiber can be taken for the groove independently, but the skeleton diameter is large, the optical cable diameter is large, the cost is high and the cost is not economical when the core number is large; the layer-stranded optical cable is characterized in that a plurality of loose sleeves are stranded to form a cable core, polyester binding yarns are bound outside the cable core to fix the positions of the sleeves and prevent the sleeves from being scattered in the subsequent processes of turnover, production, use and the like; when a certain loose sleeve is taken, all polyester binding yarns need to be cut, and other unnecessary loose sleeves are also taken out due to untwisting, and after construction, twisting and binding are manually restored, so that the efficiency is low; on the other hand, as the number of the loose tubes increases, in order to make the loose tubes fit with the loose tubes, the diameter of the central reinforcing member increases continuously, which causes diameter increase, cost increase and cannot be overcome, for example, in a 1+6 structure, 6 indicates the number of the loose tubes, the following is analogized in sequence, the diameter of the central reinforcing member is 1 time of the diameter of the loose tube, and actually is slightly larger because the loose tubes are sometimes made into an upper tolerance; in the 1+12 structure, the diameter of the central reinforcing member is 2.8637 times of the diameter of the loose tube, and is actually slightly larger, and the increased diameter of the central reinforcing member means the increase of the cost; in order to achieve the corresponding structure, the cost can be actually lower; in addition, in the prior art, no matter the layer stranded optical cable or the skeleton optical cable is formed, the diameter and the structure cannot be changed once the layer stranded optical cable or the skeleton optical cable is formed, so that the flexibility and the universality are poor.

In the application, the existence of the elevated component makes the elevated component overcome the defects in the prior art, the high extension of the elevated extension body increases the space and can form a plurality of accommodating cavities, but the reinforcement body does not need to be thick, so that the cost is saved, the weight is lightened, and the flexibility is better; the filling body realizes enough strength and firmer combination of the elevated body; the embodiments in fig. 10 to 14 of the present application not only achieve the quick replacement and assembly of the light-transmitting and electricity-transmitting components, but also achieve the quick replacement and assembly of the elevated body, so as to be more flexible and reliable, the compression and the stretching of the opening component enable the structure and the diameter of the product to be flexibly changed, the framework-type optical cable in the prior art must increase the integral diameter in order to achieve a large core number, the material cannot be reduced, the cost is high, the volume is large, and once the structure is formed, the structure cannot be changed, and once the local part is damaged, the whole structure needs to be changed; in the layer stranded optical cable in the prior art, the structure cannot be changed after the optical cable is formed, and the larger the core number is, the more the sleeves are required, the larger the diameter of the central reinforcing part is, so that the product has the defects of large diameter, high cost, heavy weight, poor flexibility, two-time cabling and the need of using a large amount of manpower, material resources, electric power, machine equipment and fields when the number is larger than twelve loose sleeves; in the application, the elevated components can be integrally formed or produced for standby and are relatively universal, and can be finished on one extrusion molding device, so that the investment of the device, the occupation of a field, the large use of personnel and the like are saved; when the device is used, the loose sleeve does not need to be withdrawn, the binding material is cut, and when the device is recovered, manual twisting and binding are not needed, only the required yarn is needed to be taken and put, so that the labor cost is saved, the efficiency is higher, and the speed is higher; the supporting cavity is formed, materials are obviously saved, and in addition, the reinforcing part does not need to be large and only needs to meet the strength requirement; through accurate accounting, compared with a layer stranded optical cable, the non-fiber comprehensive cost of the optical cable with more than 96 cores is saved by 30 percent.

The invention has the following main beneficial effects: the cost is lower, the outer diameter is smaller, the soft bending performance is better, the universality is stronger, the manufacturing speed is faster, the required equipment and the required field are fewer, the technical requirement of production personnel is lower, and the inspection and construction efficiency is higher.

The above-mentioned embodiments are merely preferred technical solutions of the present invention, and should not be construed as limiting the present invention. The protection scope of the present invention is defined by the claims, and includes equivalents of technical features of the claims. I.e., equivalent alterations and modifications within the scope hereof, are also intended to be within the scope of the invention.
