Detailed Description
In order to more clearly understand the technical scheme in the present application, the related art will be described first.
In park network, the photoelectric hybrid cable is mainly used for connection between a switch and an AP or a remote module, and for connection between the switch and the AP, the traditional scheme is to use twisted pair, so that data transmission and PoE power supply of the AP can be completed.
However, with the evolution of Wi-Fi technology, the requirements on the cable between the switch and the AP are higher and higher, and particularly, the cable is required to solve the problems of high-speed data transmission and long-distance PoE power supply in future Wi-Fi 7 technology.
In terms of bandwidth, the Wi-Fi 6 standard currently in large-scale commercial use requires that the bandwidth of the cable reach 10 Gbit/s; future Wi-Fi 7 standards require that the bandwidth of this cable be up to 40 Gbit/s. In terms of PoE power supply, the installation environment of many APs is relatively complex, poE power supply of more than 100 meters is required, for example, 300 meters or even longer PoE power supply is required by some APs in stadiums, but the power supply distance of a traditional twisted pair is only 100 meters, and the requirements cannot be met. An opto-electric hybrid cable is therefore an ideal solution for connecting a switch and an AP.
In the construction process, the photoelectric hybrid cable is also subjected to the influences of limited installation positions, environmental factors and the like, the main structure of the existing building is fixed, large-scale construction transformation cannot be performed, the installation positions of the photoelectric hybrid cable are limited, the photoelectric hybrid cable is required to be installed externally or in the existing structure, and if bending, extrusion and the like occur in the installation process, the optical fibers in the photoelectric hybrid cable can be damaged.
For this problem, it is possible to solve the problem by adding a protective structure inside the photoelectric hybrid cable, but this results in an increase in diameter and weight of the photoelectric hybrid cable, adversely affecting manufacturing costs, transportation and installation. From the aspect of environment, the influence of factors such as outdoor low temperature, underground low temperature and humidity can also influence the normal operation of the photoelectric hybrid cable.
The technical scheme in the application is further described in detail below with reference to the accompanying drawings.
The application discloses a 5G photoelectric communication cable, referring to a 1,5G photoelectric communication cable mainly comprising an outer sheath 1, a first spacer bush 2, a first optical fiber cable 3, a first filler 4, a second spacer bush 5, a cable 6, a second filler 7 and the like, wherein the first spacer bush 2 is positioned at the middle position of the outer sheath 1, and the second spacer bush 5 and the second filler 7 are filled between the outer wall of the first spacer bush 2 and the inner wall of the outer sheath 1.
The first optical fiber cable 3 is located within the first spacer 2.
In some examples, referring to fig. 2, the first optical fiber cable 3 uses an optical fiber bundle, where the first optical fiber cable 3 is composed of optical fibers 31, a cladding 32, an optical fiber sheath 33 and an integrated sheath 35, the number of the optical fibers 31 is plural, each optical fiber 31 is covered with the cladding 32, and the cladding 32 is covered with the optical fiber sheath 33. These optical fibers 31 are all located within an integrated jacket 35.
Referring to fig. 3, a first partition wing 34 is further disposed on the outer wall of the first optical fiber cable 3 (i.e. the outer wall of the integrated sheath 35), and the first partition wing 34 is uniformly disposed on the outer wall of the first optical fiber cable 3 around the axis of the first optical fiber cable 3.
In some possible implementations, the first blocking wing 34 is integrally formed with the fiber optic boot 33.
The first filler 4 is filled between the first spacer 2 and the first optical fiber cable 3, and is used for filling the space between the first spacer 2 and the first optical fiber cable 3. Here, the first partition wing 34 divides the space between the first spacer 2 and the first optical fiber cable 3 into a plurality of parts, and these spaces may or may not be communicated.
In the manufacturing process, after the first optical fiber cable 3 enters the production process, first the first filler 4 is applied around the first optical fiber cable 3, and then the first spacer 2 is manufactured on the first filler 4. In view of manufacturing difficulties, in some possible implementations, the height of the first partition wing 34 is required to be smaller than the minimum distance between the outer wall of the first optical fiber cable 3 and the inner wall of the first spacer 2, so that when the first filler 4 is applied around the first optical fiber cable 3, the first filler 4 can completely wrap the first partition wing 34, providing a smooth curved surface for manufacturing the first spacer 2, and the manufacturing process is less difficult in view of manufacturing difficulties.
In the manufacturing process, the first filler 4 is an elastic particle filler, and the elastic particle filler has certain fluidity, so that when the first optical fiber cable 3 is extruded, the first filler 4 deforms; after the pressure has disappeared, the first filling 4 can also resume its original shape.
In some possible implementations, the first filler 4 is selected from rubber particles. The rubber particles have higher elasticity, gaps are formed among the rubber particles, and when the rubber particles are extruded, the rubber particles can absorb deformation better, so that pressure is prevented from being transmitted to the first optical fiber cable 3.
Referring to fig. 1, the number of the second spacers 5 is plural, the second spacers 5 are located in the outer sheath 1 and uniformly arranged around the first spacers 2, each second spacer 5 is internally provided with a cable 6, the number of the cables 6 can be one or plural, and the remaining space in the second spacers 5 can be filled with talcum powder.
A second filler 7 is located between the outer sheath 1 and the second spacer 5 and serves to fill the remaining space within the outer sheath 1, in some possible implementations the second filler 7 also uses an elastomer particle filler, such as rubber particles.
Overall, the 5G photoelectric communication cable provided by the application has the following advantages:
the cables 6 are uniformly arranged around the first optical fiber cable 3, so that the cables 6 have higher strength and better tensile resistance, and can play a better role in protecting the first optical fiber cable 3. And the protection is uniformly distributed in the circumferential direction of the first optical fiber cable 3, so that the problem of damage to the optical fiber 31 caused by local extrusion, local stretching, overall stretching and bending in the construction process can be effectively resisted.
In the working process of the cable 6, a part of electric energy is converted into heat energy, and the heat energy can prevent the temperature of the middle part of the 5G photoelectric communication cable disclosed by the application from being too low, so that the transmission loss of the first optical fiber cable 3 caused by low temperature can be avoided. Because the expansion coefficients of the optical fiber coating layer, the plastic coating layer and the quartz are different under the low-temperature condition, the thermal expansion coefficients of the organic resin and the plastic are much larger than those of the quartz, the optical fiber is contracted at low temperature and elongated at high temperature, and microbending is generated under the action of axial compression force of the optical fiber so as to increase the loss.
The cables 6 are uniformly arranged around the first optical fiber cable 3, which is equivalent to adding a heating layer capable of actively heating around the first optical fiber cable 3, and the heating layer simultaneously gives attention to heating and protecting functions.
The hardness of the cable 6 is much higher than that of the first partition wing 34 and the first filler 4, so that the 5G optical communication cable disclosed by the application has higher structural strength and the first optical fiber cable 3 inside is in an environment with lower structural strength.
The cable 6 provides a basic support protection function, while the inner first partition wing 34 and the first filler 4 are able to absorb deformations, protecting the integrity of the first fiber optic cable 3.
Referring to fig. 4, in some examples, the second spacer 5 has a contact cambered surface 51 and a supporting cambered surface 52, which are attached to the first spacer 2, and the contact cambered surface 51 is used for increasing the contact area with the first spacer 2, so that the pressure transferred to the first spacer 2 can be more uniformly dispersed to the first spacer 2, and the deformation of the first spacer 2 is further reduced.
In some possible implementations, the arc of the contact arc 51 is equal to the arc of the outer wall of the second spacer 5.
In other possible implementations, the width of the support curve 52 tends to be smaller in the direction away from the contact curve 51, which makes it possible to obtain a second spacer 5 with a cross-section similar to a triangle, which second spacer 5 has a better stability. The second spacer 5 has better bearing capacity when being stressed, and can quickly recover the shape when the stress disappears.
In addition, when the second spacer bush 5 with the shape is deformed after being pressed, the pressure on the supporting cambered surface 52 can be only transferred to the contact cambered surface 51 in a small amount, and in the process, the pressure can be effectively prevented from being transferred to the first optical fiber cable 3.
Further, the plurality of contact cambered surfaces 51 completely cover the outer wall of the first spacer 2.
Referring to fig. 1, in some examples, a second optical fiber cable 8 is added between the outer sheath 1 and the first spacer 2, where the second optical fiber cable 8 is divided into multiple groups, and the number of the second optical fiber cables 8 in each group may be one or multiple.
Each set of second fiber optic cables 8 is located between two adjacent second spacers 5. The addition of the second optical fiber cable 8 can improve the utilization of the space within the outer sheath 1 because when the cross section of the second spacer 5 is similar to a triangle, a blank area exists between two adjacent second spacers 5, which can be used to deploy the second optical fiber cable 8.
Further, referring to fig. 5, a second partition wing 81 is disposed on the second optical fiber cable 8, the second partition wing 81 is uniformly disposed on the outer wall of the second optical fiber cable 8 around the axis of the second optical fiber cable 8, and at least one second partition wing 81 on the second optical fiber cable 8 abuts against the second spacer 5.
The function of the second blocking wing 81 is to avoid the second optical fiber cable 8 from directly contacting the second spacer 5. It will be appreciated that the second optical fibre cable 8 is subject to attenuation at high temperatures, the main reason for attenuation being the increase in inherent losses of the optical fibre. The inherent losses of an optical fiber mainly include absorption losses and scattering losses.
As the temperature increases, the absorption loss of the fiber increases, which is determined by the material properties of the fiber itself; the increase of the scattering loss of the optical fiber mainly comes from impurities in the optical fiber and hydrogen loss in a high-temperature environment, and the increase amplitude of the scattering loss is positively correlated with the temperature.
During long operation, both absorption loss and scattering loss of the optical fiber increase, so that a certain distance needs to be kept between the second optical fiber cable 8 and the second spacer 5, and meanwhile, the cladding and the optical fiber sheath also have loss due to high temperature, so that the performance of the second optical fiber cable 8 is further reduced.
Referring to fig. 6 and 7, in some examples, a metal shielding layer 21 and a heating wire 22 are further added, where the metal shielding layer 21 is wrapped on the first spacer 2, and the heating wire 22 is located on the metal shielding layer 21 and located outside the metal shielding layer 21. The metal shielding layer 21 and the heating wire 22 are to cope with extremely cold conditions.
In some possible implementations, the heating wire 22 is arranged in a two-wire manner, that is, two ends of the heating wire 22 are located at the same connection end of the 5G photoelectric communication cable disclosed in the present application of the metal shielding layer 21, and two ends of the heating wire 22 are connected with a connection interface at the connection end.
When the 5G optical-electrical communication cable disclosed by the application is in an extremely cold environment, the heating wire 22 is started and converts electric energy into heat energy, and the heat energy of the heat wire can raise the temperature of the metal shielding layer 21, and then raise the temperature of the environment where the first optical fiber cable 3 positioned in the metal shielding layer 21 is positioned.
The metal shielding layer 21 is used for uniformly dispersing the heat generated by the heating wire 22 around the first optical fiber cable 3.
In some possible implementations, the heating wire 22 is helically wound on the outside of the metal shielding layer 21.
The application also discloses a communication system comprising any 5G photoelectric communication cable described in the above.
The embodiments of the present application are all preferred embodiments of the present application, and are not intended to limit the scope of the present application in this way, therefore: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
