Problems solved by technology
Furthermore, the current conventional non-ribbon optical cable has a maximum number of cores of 288 cores (including 288 optical cables). Using a ribbon optical cable will lead to an excessively large overall size of the optical cable, which requires extremely high application space, which is not conducive to the implementation of subsequent laying operate

Embodiment Construction
[0024] Below in conjunction with specific embodiment, content of the present invention is described in further detail, figure 1 It shows a schematic structural view of the first embodiment of the 5G ultra-large-core optical cable in the present invention. It can be seen that it is mainly composed of several parts such as the central strength member 1, the signal transmission body 2, and the first sheath layer 3. Among them, the central The reinforcement member 1 , the signal transmission body 2 , and the first sheath layer 3 are sequentially and concentrically fitted together along the direction from inside to outside. Such as figure 2 As shown in , the signal transmission body 2 is at least divided into functional layers placed at a certain distance for signal transmission, which are respectively an inner layer signal transmission unit 21 and an outer layer signal transmission unit 22 . The inner layer signal transmission unit 21 is composed of 12 inner layer core wires 211...

The invention relates to a 5G optical cable with an ultra-large number of cores. The 5G optical cable comprises a central reinforcing member, a signal transmission body and a first sheath layer which are concentrically sleeved in sequence along the radial direction. The signal transmission body comprises an inner-layer signal transmission unit and an outer-layer signal transmission unit which are sleeved concentrically. The inner-layer signal transmission unit and the outer-layer signal transmission unit are both composed of a plurality of core wires which are circumferentially twisted around the central axis of the central reinforcing member. Each core wire is formed by concentrically sleeving an optical fiber bundle, a fiber paste filling body and a loose tube. Each optical fiber bundle is formed by integrating a plurality of optical fibers. In actual forming and manufacturing of the optical cable, the total number of optical fibers, the outer diameter of the optical fibers, the outer diameter of the loose tube, the total number of the signal transmission units and the outer diameter of the first sheath layer which are used for forming the optical fiber bundle are controlled. Therefore, on the premise of ensuring the large-core-number data transmission capability, the cross section size of the molded optical cable can be effectively reduced, and the self weight in unit length is reduced.
Description
technical field [0001] The invention relates to the technical field of communication optical cable manufacturing, in particular to an optical cable with a super large number of cores for 5G. Background technique [0002] As the demand for information continues to grow, optical fiber communication is widely used as the communication method with the fastest signal transmission speed and the best transmission quality. Today, with the rapid development of network construction, the application of optical cables is becoming more and more extensive. [0003] According to the different laying environment of the optical cable, it is divided into indoor optical cable and outdoor optical cable. Low, even breaks during operation, causing great hidden dangers to economy and safety. At present, all optical cables in the industry use Kevlar (aramid) or glass fiber yarn as reinforcement elements, which can improve the tensile performance of optical cables and avoid cable breakage in extre...
