Description
Technical Field
[0001] The utility model belongs to the technical field of communication equipment, and in particular relates to a photoelectric composite cable with a special structure. Background Art
[0002] In optoelectronic communication systems, transmission carriers are key components for achieving connections between devices. In order to improve the stability of communication signals, it is necessary to use wired communication optical cables to transmit network signals. Network cables refer to cables used to transmit network data signals. They are mainly used to connect computers, network devices or other data communication equipment to achieve data transmission and communication. Network cables are usually various cable types used for local area networks, wide area networks or Internet connections. Different types of network cables have different characteristics and uses. Choosing the right network cable depends on factors such as specific application requirements, transmission distance, bandwidth requirements and environmental conditions.
[0003] In the existing technology, network cables are usually used as carriers, and Ethernet POE power supply technology is used to solve the communication and power supply problems between devices with a single network cable. However, there are the following shortcomings:
[0004] 1. Limited transmission rate: Traditional network cables only support the transmission of electrical signals in copper wires, which are relatively slow and susceptible to electromagnetic interference;
[0005] 2. Limited transmission distance and bandwidth: Traditional network cables cannot cover the transmission distance. As the transmission distance increases, the attenuation will gradually increase, affecting the signal quality and transmission rate. The transmission distance is generally only within 100 meters.
[0006] 3. Limited application scenarios: Traditional network cables are mainly used for local area network construction, office, home and other short-distance data transmission, such as computer connection, network device connection, etc.
[0007] Therefore, a special structure of optical-electric composite cable is needed to solve the problems of limited network line transmission rate, limited transmission distance and bandwidth, and limited application scenarios in the existing technology. Utility Model Content
[0008] The purpose of the present utility model is to provide a photoelectric composite cable with a special structure to solve the problems raised in the above background technology.
[0009] To achieve the above-mentioned objectives, the present invention provides the following technical solution: a photoelectric composite cable with a special structure, comprising a flame-retardant outer sheath, a Kevlar fiber protective layer provided at the center of the flame-retardant outer sheath, a fiber paste provided inside the Kevlar fiber protective layer, an optical fiber core installed inside the fiber paste, PE insulation layers provided near both sides of the flame-retardant outer sheath, and oxygen-free copper conductor power cords installed inside the two PE insulation layers.
[0010] It should be noted that the flame retardant outer cover is made of PVC material.
[0011] It is further worth mentioning that the flame retardant outer cover is designed to be flat, and the corners of the flame retardant outer cover are all chamfered.
[0012] It should be further explained that the Kevlar fiber protective layer is woven from a plurality of Kevlar fibers.
[0013] As a preferred embodiment, the optical fiber core is made of glass fiber material.
[0014] As a preferred embodiment, the two oxygen-free copper conductor power lines are symmetrically arranged on both sides of the optical fiber core.
[0015] As a preferred embodiment, the optical fiber core and the oxygen-free copper conductor power line are provided with independent shielding layers.
[0016] Compared with the prior art, the optical-electric composite cable with a special structure provided by the present invention has at least the following beneficial effects:
[0017] (1) By combining optical fiber and network cable, a multifunctional transmission carrier is formed, which has the high-speed data transmission capability of optical fiber and integrates the function of power transmission. The optical fiber core and oxygen-free copper conductor power cable adopt independent shielding layers, which effectively reduces electromagnetic interference and optical fiber transmission loss, improves the transmission performance of optoelectronic composite cable, maintains a relatively independent structure, and is convenient for introduction, extraction and connection during installation.
[0018] (2) By optimizing the structural design of optical fiber and cable, the problem of long-distance transmission and power supply between devices can be solved at one time. There is no need to repeatedly lay multiple lines. One information composite cable can solve the problem, reducing the space occupied by cables and saving the cost of repeated wiring. At the same time, the optical fiber core is made of glass fiber material, and the production grinding process is strengthened. The attenuation coefficient reaches the telecommunications grade standard, and the maximum high-speed data transmission can reach 100Gbps, and the transmission distance can reach 3 kilometers.
[0019] (3) By combining optical fiber and cable, the equipment can be powered at the same time during long-distance high-speed optical fiber transmission, reducing the space and cost required for wiring. The overall outer diameter is small, the weight is light, the flexibility is high, and the construction and laying are convenient. It can stably transmit in humid, high-temperature, corrosive gas and other environments without affecting performance. It can be used in long-distance communications, power system monitoring, intelligent transportation systems and other fields, especially in situations where high-speed and long-distance transmission is required.

[0024] The present invention will be further described below with reference to the embodiments.
[0025] See also Figure 1-3 The utility model provides an optoelectronic composite cable with a special structure, including a flame-retardant outer sheath 1, a Kevlar fiber protective layer 2 is arranged at the center position inside the flame-retardant outer sheath 1, a fiber paste 3 is arranged inside the Kevlar fiber protective layer 2, an optical fiber core 4 is installed inside the fiber paste 3, PE insulation layers 5 are arranged near both sides of the flame-retardant outer sheath 1, and oxygen-free copper conductor power lines 6 are installed inside the two PE insulation layers 5.
[0026] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth mentioning that the flame retardant outer sheath 1 is made of PVC material. PVC material has good flame retardant properties. Even in a fire or high temperature environment, it can effectively slow down the spread of flames and enhance the safety of the use of optoelectronic composite cables. PVC has good electrical insulation properties and can effectively block the interference of the internal current of the wires to the outside world. At the same time, it protects the current in the line from external interference, ensuring the stability and reliability of signal transmission. At the same time, PVC material has good wear resistance and durability, and can resist physical damage and environmental corrosion in daily use, extend the service life of the optoelectronic composite cable, and reduce maintenance and replacement costs. PVC is a common plastic material. , the manufacturing cost is relatively low, and the manufacturing cost can be controlled while ensuring performance, which is suitable for large-scale applications and wide market demand; when used in outdoor environments, the flame retardant outer sheath 1 can be replaced with a waterproof PE outer sheath. The PE material has good waterproof properties and can effectively block the intrusion of external moisture and humidity, protecting the optical fiber and the inside of the cable from moisture corrosion. It is especially important for outdoor wiring or environments that require frequent contact with water, such as underground communication pipelines, underwater communications and other scenarios. At the same time, the PE material has strong resistance to ultraviolet rays and weather changes, and can operate stably for a long time in outdoor environments without being affected by material aging, ensuring the stability and reliability of the optoelectronic composite cable under various climatic conditions.
[0027] Further as Figure 1 、 Figure 2 and Figure 3As shown, it is worth mentioning that the flame retardant outer sheath 1 is designed in a flat shape. The flat design and the rounded corners make the optoelectronic composite cable easier to install and wire. The rounded corners can reduce the jamming and resistance during wiring, which helps to improve installation efficiency and reduce possible damage during installation. At the same time, the flat design can make more effective use of space and is visually neater and more beautiful than traditional round cables. The corners of the flame retardant outer sheath 1 are all chamfered. The rounded corners can effectively reduce the wear and cracks on the cable sheath caused by cutting or damage to the corners during installation and use. This is especially important for optoelectronic composite cables because they usually need to bend and move in complex environments. Avoiding sharp corners can significantly extend their service life. At the same time, the rounded corner design helps to disperse the stress concentration of the cable under bending and tension, thereby improving its overall tensile strength. It is especially important for places that require frequent movement and bending (such as mobile equipment or places where people frequently enter and exit).
[0028] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the Kevlar fiber protective layer 2 is woven from multiple strands of Kevlar fiber. Kevlar fiber is an extremely strong synthetic fiber with a tensile strength greater than that of steel. Therefore, a protective layer woven with Kevlar fiber can significantly improve the overall tensile strength of the optical fiber composite cable, resulting in excellent performance under tensile and torsional stress. Kevlar fiber also has excellent wear resistance, effectively resisting physical wear and damage from the external environment. This durability is particularly suitable for applications that require frequent movement or use in complex environments. At the same time, its density is very low, so the protective layer woven with Kevlar fiber can achieve a lightweight design. This not only reduces the weight of the entire cable, but also reduces the load on the supporting and suspension structures, facilitating installation and maintenance in complex wiring environments. Compared with traditional metal protective layers, the production process of Kevlar fiber has a smaller impact on the environment, meeting modern society's requirements for environmental protection and sustainable development.
[0029] According to the above working process, it can be seen that: through the combination of optical fiber and cable, during long-distance high-speed optical fiber transmission, power is supplied to the equipment at the same time, reducing the space and cost required for wiring. The overall outer diameter is small, the weight is light, the flexibility is high, the construction and laying are convenient, and stable transmission is achieved in humid, high-temperature, corrosive gas and other environments without affecting performance. It can be used in long-distance communications, power system monitoring, intelligent transportation systems and other fields, especially in situations requiring high-speed and long-distance transmission.
[0030] Further as Figure 1 、 Figure 2 and Figure 3As shown, it is worth mentioning that the optical fiber core 4 is made of glass fiber, which has very low transmission loss and can support long-distance data transmission of up to hundreds of kilometers. Its low attenuation characteristics ensure the stability and reliability of data during transmission, and is suitable for application scenarios requiring high bandwidth and long-distance transmission. Through enhanced production and grinding technology, the attenuation coefficient reaches the telecommunications-grade standard, and the 1310 wavelength can reach 0.32db / KM (industry standard 0.4db / KM), and the 1550 wavelength can reach 0.18db / KM (industry standard 0.3db / KM).
[0031] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the two oxygen-free copper conductor power lines 6 are symmetrically arranged on both sides of the optical fiber core 4. The oxygen-free copper conductor power lines 6 are squeezed into the HD3364 imported PE insulation layer 5. The symmetrical arrangement of the oxygen-free copper conductor power lines 6 helps to maintain the overall structural balance of the optoelectronic composite cable, which is crucial for the installation and maintenance of the cable. It can reduce unnecessary tension or problems caused by structural imbalance and extend the service life of the cable.
[0032] Further as Figure 1 、 Figure 2 and Figure 3 As shown, it is worth noting that the optical fiber core 4 and the oxygen-free copper conductor power line 6 are provided with independent shielding layers. Optical fiber communication and power lines belong to different signal transmission systems, and their operating frequencies and signal types are quite different. By providing independent shielding layers for the optical fiber core 4 and the oxygen-free copper conductor power line 6 respectively, the electromagnetic interference between them can be effectively reduced. This isolation can ensure the stability of the optical signal and the reliability of data transmission without affecting the stable power supply of the power line, maintaining a relatively independent structure, facilitating the introduction, lead-out and connection during installation, and having a smaller bending radius.
[0033] This solution has the following working process: in actual use, the optical fiber and network cable are combined to form a multifunctional transmission carrier, which has the high-speed data transmission capability of optical fiber and integrates the power transmission function, solving the long-distance transmission and power supply problems between devices at one time, without the need to repeatedly lay multiple lines; the optical fiber core 4 is protected by six 1000D Kevlar fibers, the oxygen-free copper conductor power cord 6 is extruded into the HD3364 imported PE insulation layer 5, and the structure is extruded into the flame-retardant outer jacket 1, forming a compact flat finished cable as a whole.
[0034] In summary: by combining optical fiber and cable, during long-distance high-speed optical fiber transmission, power is supplied to the equipment at the same time, reducing the space and cost required for wiring. The overall outer diameter is small, the weight is light, the flexibility is high, the construction and laying are convenient, and the transmission is stable in humid, high-temperature, corrosive gas and other environments without affecting the performance. It can be used in long-distance communications, power system monitoring, intelligent transportation systems and other fields, especially in situations where high-speed and long-distance transmission is required; by combining optical fiber and network line, a multifunctional transmission carrier is formed, which has the high-speed data transmission capability of optical fiber and integrates the function of power transmission. The optical fiber core 4 and the oxygen-free copper conductor are electrically conductive. The source line 6 adopts an independent shielding layer to effectively reduce electromagnetic interference and optical fiber transmission loss, improve the transmission performance of the optoelectronic composite cable, maintain a relatively independent structure, and facilitate the introduction, lead-out and connection during installation; by optimizing the structural design of optical fiber and cable, the long-distance transmission and power supply problems between devices are solved at one time. There is no need to repeatedly lay multiple lines. One information composite cable can solve the problem, reducing the space occupied by the cable and saving the cost of repeated wiring; at the same time, the optical fiber core 4 is made of glass fiber material, and the production grinding process is strengthened. The attenuation coefficient reaches the telecommunications grade standard, and can reach up to 100Gbps high-speed data transmission and a transmission distance of up to 3 kilometers.
