Description
Technical Field
The invention belongs to the technical field of communication, cables and electric power, and particularly relates to a layered optical cable and a high-density optical cable.
Background
Along with the rapid construction of the 5G network, the use amount of the optical cable is increasing day by day, and China is in a high demand stage as the country with the fastest construction, the earliest and the most network coverage of the 5G network; with 5G applications, the demand for foreign fiber optic cables is also rapidly increasing. 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.
From a layout point of view, the applicant believes that the optical cable is missing; the requirements of RRU, BBU, power fiber to the home and the like can not be met, and multiple functions can not be realized by laying once. In addition, the applicant believes that there is a possibility of further improvement in structure and reduction in cost; therefore, the applicant makes further compensation and obtains beneficial technical effects.
