Background
In 2017, the 4G wide coverage stage of China is basically finished, the number of 4G base stations reaches millions (covering 99% of population), and the direct total investment is about billions; the Ministry of industry and correspondence of 6 months in 2019 officially issued 5G commercial license plates, the magnitude of the demand of 5G base stations is ten million, and the demand of the base stations for cables also meets a new peak. However, in the face of the huge base station cable requirement, the contradiction of the increasingly compact wiring space is faced; especially the distance from the signal tower to the machine room, the optical cable part, the power line and the data cable of the existing signal tower are respectively and independently laid downwards; the multiple cables are laid independently, so that the installation is troublesome, the cost is high, and the data line, the power line and the optical cable need to be protected independently to deal with the complex outdoor use environment.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defects of the prior art and provides a photoelectric combined cable for a 5G tower; the combined cable has the characteristics of high-frequency data transmission, huge access bandwidth, strong electromagnetic wave interference resistance and capability of solving the problem of equipment power consumption.
In order to achieve the above purpose, the utility model provides a technical scheme is:
a photoelectric combined cable for a 5G tower comprises an optical cable; the method is characterized in that: the outer circumference of the optical cable is provided with a plurality of CAT5e data lines and two power lines, and then a ceramic tape, an armored aluminum tape and a sheath are sequentially coated from inside to outside.
The CAT5e data line is an unshielded twisted pair; is composed of multiple twisted pairs and a plastic sheath.
The gaps between the CAT5e data lines, power lines and ceramic tape are filled with PP mesh cords.
Two tearing ropes are further arranged in the ceramic belt and arranged along the length direction of the photoelectric combined cable.
The utility model has the advantages that:
1. the CAT5e data line can transmit high frequency data;
2. the two power lines can independently supply power to the system;
3. the optical cable can provide huge bandwidth access and has strong anti-electromagnetic wave interference capability;
4. meanwhile, a plurality of transmission technologies are provided, and the device has strong adaptability, strong expandability and wide product application range;
5. the optical cable, the power line and the data cable are independently cabled at one time, so that the power supply problem of equipment is solved, and secondary wiring is avoided;

Drawings
Fig. 1 is an enlarged schematic cross-sectional view of an embodiment of the present invention.
Detailed Description
The invention will be further described with reference to the following examples, which are illustrated in the accompanying drawings.
The utility model discloses a satisfy the demand of user to the saving in cost and space, provide the solution of disposable construction (avoiding the secondary construction), one-stop formula for the customer.
The photoelectric combined cable for the 5G tower comprises an optical cable 7 arranged at the central part; the optical cable is a multi-core optical cable (prior art), and comprises a plurality of optical fibers (the number of the optical fibers can be determined according to needs); there is shown an 18-core fiber optic cable comprised of three loose tubes (each containing six optical fibers) and two reinforcing cords. The structure is similar to the existing combined cable.
The improvement of the utility model is that a plurality of CAT5e data 4 and two power supplies 5 are arranged on the outer circumference of the optical cable; the CAT5e data lines and the power lines are arranged in parallel with each other and extend along the length direction of the combined cable; then, the CAT5e data line 4 and the power line 5 are coated by the ceramic tape 3, and then the armored aluminum tape 2 and the sheath 1 (preferably a medium-density polyethylene material) are sequentially coated from inside to outside; the gaps between the CAT5e data lines, power lines and ceramic tape are filled by PP mesh 8.
The AT5e data line is an unshielded twisted pair formed of multiple twisted pairs and a plastic sheath.
Two tearing ropes 6 are further arranged in the ceramic belt and arranged along the length direction of the photoelectric combined cable.
The utility model discloses a design point:
1. the optical cable is designed by using all media, so that the influence of metal materials on the performance transmission of the data line is prevented;
2. the power line adopts American standard THHT requirement to ensure the performance of the power line;
3. the 18-core optical cable is produced by adopting a layer-stranding structure, has a stable structure, enables the optical fiber to generate certain stranding extra length, and ensures the bending property, the mechanical property and the temperature attenuation property of the optical fiber, and the 18-core optical cable is respectively arranged in three 3 loose tubes, so that a movable connector is conveniently additionally arranged.
4. The cabling procedure adopts a ceramic tape wrapping mode to fix 6 CAT5e data cables, an 18-core optical cable and 2 THHT12AWG power lines, and has the characteristics of uniform stress and weak influence on the data cables; and the traditional yarn binding fixing mode is not used, so that the influence on the attenuation performance of the data cable due to the stress concentration of the yarn binding point of the data cable is prevented.
5. When the sheath is produced, the extrusion temperature is up to 230 ℃, heat is easily conducted into the sheath through an aluminum tape, so that the sheath of the data cable and the power line is melted and deformed, the appearance is influenced, and the performance of the data cable and the power supply is also influenced to a certain extent; therefore, the ceramic belt with a good heat insulation effect is selected in the cabling process, heat is isolated outside the belt when the sheath is guaranteed, the data cable and the power line are protected from being influenced by the sheath process, and the performance of each part is guaranteed to meet the design requirement.
