All optical cables in the industry at present adopt a Kevlar (aramid) or glass fiber yarn reinforcing element mode, the tensile property of the optical cables can be improved, and the optical cables are prevented from being broken in an extreme environment. In addition, under the development background of 5G large data transmission, the optical cable is required to contain enough optical fibers to improve the transmission capability. It is known that as the number of optical fibers (i.e., the number of cores) in an optical cable increases, the more material used in the optical cable increases its weight, the more kevlar (aramid) is used, and the cost increases geometrically. Furthermore, the maximum number of cores of the conventional non-ribbon optical cable is 288 cores (including 288 optical cables), and the application of the ribbon optical cable results in an oversize of the whole optical cable, which has extremely high requirements on application space, and is further not beneficial to executing subsequent laying operations. Thus, a skilled person is urgently needed to solve the above problems.

The outer layer signal transmission unit is sleeved on the periphery of the inner layer signal transmission unit and consists of N outer layer core wires which are also circumferentially stranded around the central axis of the central reinforcement. The inner layer core wire and the outer layer core wire have the same design structure. Only for the inner core wire, it is composed of the optical fiber bundle, the fiber paste filling body and the loose tube which are concentrically sleeved from the inside to the outside. The optical fiber bundle is formed by assembling Q optical fibers. (M + N) Q > 288. Assuming that the outer diameter of the optical fiber is D1, D1 is less than or equal to 0.25 mm.

Detailed Description
The present invention will be described in further detail with reference to specific examples, and fig. 1 shows a schematic structural diagram of a first embodiment of an optical cable with an ultra-large core number for 5G in the present invention, which is mainly composed of a central strength member 1, a signal transmission member 2, and a first sheath layer 3, wherein the central strength member 1, the signal transmission member 2, and the first sheath layer 3 are concentrically sleeved in sequence from inside to outside. As shown in fig. 2, the signal transmission body 2 is divided into at least a functional layer for signal transmission, which is disposed at a certain distance, and includes an inner layer signal transmission unit 21 and an outer layer signal transmission unit 22. The inner layer signal transmission unit 21 is constituted by 12 inner layer core wires 211 twisted circumferentially around the center axis of the center reinforcement 1. The outer signal transmission unit 22 is sleeved on the periphery of the inner signal transmission unit 21, and is composed of 16 outer core wires 221 which are also twisted around the central axis of the central reinforcement member 1. The inner layer core wire 211 and the outer layer core wire 221 have the same design structure. Only the inner core wire 211 is composed of an optical fiber 2111, a fiber paste filler 2112, and a loose tube 2113 concentrically arranged from the inside to the outside. The fiber bundle 2111 is formed by collecting 36 g.654.e fibers 21111 (as shown in fig. 3), so that the total core number of the 5G extra-core cable is controlled at 1080. Assuming that the outer diameter of the optical fiber 21111 is D1, D1 is 0.25mm or less. Assuming that the outer diameter of the loose tube 2113 is D2, D2 is less than or equal to 1.8 mm. The outer diameter value (i.e., the size of the optical fiber cable) of the first sheath layer 3 varies depending on the number of optical fibers added, and generally, assuming that the outer diameter value of the first sheath layer 3 is D3, D3 is not easily larger than 10mm in terms of convenience of laying construction and reduction of self weight. Therefore, on one hand, the single optical cable contains 1008 optical fibers, and compared with 288 cables in the market, the number of the optical fibers is increased in geometric grade, which is enough to satisfy all the current 5G application scenarios; on the other hand, the inner layer signal transmission unit 21 and the outer layer signal transmission unit 22 are stranded around the central reinforcement in a layered manner, and the formed optical cable is cylindrical as a whole, so that the compact and miniature design is more favorably realized on the premise of the same transmission capacity compared with the traditional ribbon optical cable; on the other hand, in the molding manufacture of the optical cable, the total number of the optical fibers 21111 for forming the signal transmission unit, the outer diameter of the G.654.E optical fiber 21111, the outer diameter of the loose tube 2113, the total number of the signal transmission unit and the outer diameter of the first sheath layer 3 are controlled, so that the miniaturization design of the optical cable is ensured, the section size of the molded optical cable is effectively reduced, the self weight in unit length is reduced, and the probability of accidental breakage of the optical cable caused by the over-limit tension in the follow-up process is greatly reduced.
As is known, g.654.e optical fiber is mainly suitable for terrestrial transmission systems, and can increase the effective area of the optical fiber and reduce the attenuation coefficient of the optical fiber on the premise of keeping the basic performance of the single-mode optical fiber used in the terrestrial applications consistent with that of the existing single-mode optical fiber, thereby improving the 400G transmission performance.
However, the following points need to be explained here: 1) in addition to the g.654.e optical fiber 21111 for signal transmission, other small-diameter optical fibers may be selected according to the production cost budget and the actual process capability of the plant; 2) the number of inner core wires 211 for forming the inner signal transmission unit 21, the number of outer core wires 221 for forming the outer signal transmission unit 22, and the number of g.654.e optical fibers 21111 wrapped in the loose tube 2113 may be specifically set according to different practical application scenarios and customer requirements; 3) in the above embodiment, a 1080-core optical cable molding structure is disclosed, that is, the number of inner core wires 211 is set to 12, the number of outer core wires 221 is set to 16, and the number of optical fibers included in either the inner core wires 211 or the outer core wires 221 is set to 36. In actual production and manufacturing, the quantity can be selected according to actual application scenes and customer requirements; 4) in practical applications, if the inside of the optical cable is immersed in water, the optical fiber will be damaged by expansion in a cold water icing environment, and the attenuation of the optical cable will be increased, thereby affecting the signal transmission. In view of this, in the above embodiment, the g.654.e optical fiber 21111 is wrapped with the paste filler 2112 at its outer periphery so as to be protected from moisture.
Fig. 4 is a schematic structural diagram of a second embodiment of the extra-large core number optical cable for 5G in the present invention, which is different from the first embodiment in that: 1) the signal transmission body 2 is also internally provided with a water-blocking yarn layer 23, an inner water-blocking tape layer 24 and an outer water-blocking tape layer 25. As is clear from fig. 4, the water blocking yarn layer 23 is interposed between the center reinforcing member 1 and the inner layer signal transmission unit 21, and is composed of a plurality of water blocking yarns twisted circumferentially around the outer side wall of the center reinforcing member 1. The inner water blocking tape layer 24 is interposed between the inner signal transmission unit 21 and the outer signal transmission unit 22, and is formed of a plurality of inner water blocking tapes which are circumferentially twisted around the outer side wall of the inner signal transmission unit 21. The outer water blocking tape layer 25 is formed by a plurality of outer water blocking tapes which are twisted around the outer side wall of the outer signal transmission unit 22 in the circumferential direction. Therefore, when the optical cable is attacked by water, the inner water-blocking tape layer 24 and the outer water-blocking tape layer 25 which are arranged outside can form two mutually independent water-blocking layers, even if a small amount of water is successfully invaded, the water-blocking yarns with high water absorbability can absorb the water, and the subsequent attack on the inner core wire 211 and the outer core wire 221 is avoided; 2) the central reinforcing member 1 is subjected to a plastic coating process to form a PE plastic layer 11 on the periphery thereof. After the optical cable is formed, the existence of the PE plastic layer 11 can effectively prevent the water blocking yarn layer 23 and the inner core wire 211 from sliding axially, which is beneficial to ensuring the forming regularity of the inner signal transmission unit 21.
It should be noted that, in the process of forming and manufacturing the optical cable, the forming thickness of the inner water-blocking tape layer 24 and the outer water-blocking tape layer 25 is limited for controlling the outer diameter of the whole optical cable, and is generally not more than 0.5 mm.
Fig. 5 is a schematic structural diagram of a third embodiment of the extra-large core number optical cable for 5G in the present invention, which is different from the second embodiment in that: an aerogel layer 4 is sandwiched between the outer water-blocking tape layer 25 and the first sheath layer 3. The aerogel layer 4 is formed directly on the outer water-blocking tape layer 25. In the practical application of the optical cable, the aerogel exerts very excellent heat insulation performance, so that the inner signal transmission unit 21 and the outer signal transmission unit 22 inside the aerogel are thermally insulated from the external environment, and the influence of the external high-temperature or low-temperature environment on the signal transmission performance is avoided.
Fig. 6 is a schematic structural diagram of a fourth embodiment of the extra-large core number optical cable for 5G in the present invention, which is different from the third embodiment in that: the periphery of the first sheath layer 3 is wrapped with a second sheath layer 5. The existence of second restrictive coating 5 can further promote the protective capacities of optical cable effectively, reduces its probability that receives the impaired phenomenon of exogenic action and takes place.
In addition, as a further optimization of the structure of the 5G extra-large core optical cable, the second sheath layer 5 is preferably formed by extrusion molding of transparent nylon plastic, so that the second sheath layer has a light transmission function. After the cable is laid, a series of light sources (e.g., illumination level lasers) are added along its length. Therefore, on one hand, the light is transmitted by utilizing the light-transmitting characteristic of the second sheath layer, so that the optical cable emits weak light at night, and birds, beasts, squirrels and the like can be wound away to play a role in preventing the living beings from biting; on the other hand, be convenient for outdoor operating personnel to come the discernment optical cable night, do benefit to the execution and lay or the execution of later maintenance work.
Fig. 7 is a schematic structural diagram of a fifth embodiment of the 5G extra-large core optical cable according to the present invention, which is different from the fourth embodiment in that: a graphene thermal film layer 6 is additionally arranged between the first sheath layer 3 and the second sheath layer 5. The graphene thermal film 6 has good heat conductivity and low cost (10-20 yuan per square meter). In the practical application of the optical cable, energy level lasers are additionally arranged at two ends of the optical cable, and heat is transferred to the surface of the optical cable through the high heat conduction performance of the graphene thermal film 6, so that ice coating is prevented from being formed on the surface of the optical cable, and the ice coating resistance effect is achieved.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
