Description

Technical Field

[0001] This utility model relates to the technical field of hybrid optical cables, and in particular to a hybrid optical cable that is easy to lay. Background Technology

[0002] my country is currently in a stage of rapid development in the communications industry. The arrival of the 5G era presents both opportunities and challenges for the industry. At present, 5G networks are already in operation, and intricate optical fiber cables have spread all over the country. Due to the diversity of functions, optical fiber composite cables have complex cable structures. However, with reasonable structural design, the functions of composite cables can be better realized and satisfied, and manufacturing costs can be reduced while meeting manufacturing standards, thereby maximizing benefits.

[0003] At present, optical cables and electrical cables are mostly separate and independent. If communication and power supply are required at the same time, optical cables and electrical cables generally need to be laid separately. However, this increases both the procurement cost of the products and the construction cost of laying the transmission cables. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a hybrid optical cable that is easy to lay, which reduces procurement and installation costs.

[0005] This utility model discloses an easy-to-lay hybrid optical cable, wherein the hybrid optical cable is configured with a butterfly structure, comprising:

[0006] Two low-smoke halogen-free flame-retardant polyolefin outer sheaths, and the low-smoke halogen-free flame-retardant polyolefin outer sheaths are configured as a flat structure.

[0007] The optical fiber is installed inside a low-smoke halogen-free flame-retardant polyolefin outer sheath, and the optical fiber is laid along the length of the low-smoke halogen-free flame-retardant polyolefin outer sheath.

[0008] The feeder cable is installed inside another low-smoke halogen-free flame-retardant polyolefin outer sheath, and the feeder cable is laid along the length of the low-smoke halogen-free flame-retardant polyolefin outer sheath.

[0009] Furthermore, the two low-smoke, halogen-free, flame-retardant polyolefin outer sheaths are connected by a central hanger, facilitating their separation during installation.

[0010] As a preferred option, the low-smoke halogen-free flame-retardant polyolefin outer sheath is symmetrically provided with V-shaped grooves. The V-shaped grooves are arranged along the length of the optical cable. The V-shaped grooves can ensure that the low-smoke halogen-free flame-retardant polyolefin outer sheath can be easily removed, and also ensure the overall mechanical strength and service life of the hybrid optical cable.

[0011] Furthermore, the low-smoke halogen-free flame-retardant polyolefin outer sheath containing optical fibers is also equipped with a reinforcing member inside, and the reinforcing member is arranged along the length direction of the low-smoke halogen-free flame-retardant polyolefin outer sheath.

[0012] Preferably, an isolation layer is provided on the outer wall of the feeder cable to prevent signal interference.

[0013] Furthermore, the outer surface of the optical fiber is coated with a waterproof layer to effectively prevent moisture from entering.

[0014] As a preferred option, the surface of the low-smoke, halogen-free, flame-retardant polyolefin outer sheath has an anti-UV coating, which extends the service life of the optical cable.

[0015] Furthermore, the low-smoke, halogen-free, flame-retardant polyolefin outer sheath material is selected from polyethylene, polypropylene, or copolymers thereof.

[0016] A hybrid optical cable designed for easy installation features a butterfly-shaped structure and flat design that significantly reduces the cable's bending radius, making it easier to lay. This makes it particularly suitable for applications in narrow spaces or complex paths. The low-smoke, halogen-free, flame-retardant polyolefin outer sheath not only improves the cable's safety but also reduces harmful smoke generated in the event of a fire, ensuring the safety of the installation environment and personnel. The optical fiber has high bandwidth and low loss characteristics, ensuring efficient and stable data transmission. The feeder cable provides a stable power supply to meet the equipment's power requirements. Attached Figure Description

[0022] This utility model relates to a hybrid optical cable that is easy to lay, such as... Figures 1 to 3 As shown, the hybrid optical cable is configured with a butterfly-shaped structure, including:

[0023] Two low-smoke halogen-free flame-retardant polyolefin outer sheaths 1, and the low-smoke halogen-free flame-retardant polyolefin outer sheaths 1 are configured as a flat structure.

[0024] Optical fiber 2 is disposed inside a low-smoke halogen-free flame-retardant polyolefin outer sheath 1, and optical fiber 2 is laid along the length of the low-smoke halogen-free flame-retardant polyolefin outer sheath 1. Optical fiber 2 is responsible for data transmission and has the characteristics of high bandwidth and low loss.

[0025] Feeder wire 3 is installed inside another low-smoke halogen-free flame-retardant polyolefin outer sheath 1, and feeder wire 3 is laid along the length of low-smoke halogen-free flame-retardant polyolefin outer sheath 1. Feeder wire 3 is used to provide power supply to meet the power demand of the equipment.

[0026] The butterfly structure and flat design significantly reduce the bending radius of the optical cable, making it easier to lay. It is particularly suitable for applications in narrow spaces or complex paths. The low-smoke, halogen-free, flame-retardant polyolefin outer sheath 1 not only improves the safety of the optical cable but also reduces harmful smoke generated in the event of a fire, ensuring the safety of the laying environment and personnel. The optical fiber 2 has the characteristics of high bandwidth and low loss, ensuring the efficiency and stability of data transmission. The feeder cable 3 provides a stable power supply to meet the power needs of the equipment.

[0028] The design of the central neck 4 allows the optical cable to maintain its integrity during the laying process, and it can also be easily separated as needed, making it particularly suitable for application scenarios in narrow spaces or complex paths.

[0029] As a preferred option, such as Figure 1 and Figure 3 As shown, the low-smoke halogen-free flame-retardant polyolefin outer sheath 1 is symmetrically provided with V-shaped grooves 5. The V-shaped grooves 5 are arranged along the length of the optical cable. The V-shaped grooves 5 can ensure that the low-smoke halogen-free flame-retardant polyolefin outer sheath 1 can be easily stripped, and also ensure the overall mechanical strength and service life of the hybrid optical cable.

[0030] The V-groove 5 design allows the low-smoke, halogen-free, flame-retardant polyolefin outer sheath 1 to be easily peeled off along the V-groove 5 when needed, significantly simplifying the terminal handling and maintenance process and improving work efficiency. The V-groove 5 design does not damage the overall appearance of the optical cable, maintaining the neatness and aesthetics of the optical cable, and is suitable for various application scenarios.

[0032] The reinforcement 6 significantly improves the overall mechanical strength and tensile properties of the optical cable, ensuring that the optical cable is not easily damaged by mechanical forces during laying and long-term use, thus extending its service life. The design of the reinforcement 6 does not affect other functions and structures of the optical cable, making it suitable for various application scenarios, especially for occasions that require the cable to withstand large tensile or compressive forces.

[0033] As a preferred option, such as Figure 1 and Figure 3 As shown, the feeder cable 3 has an isolation layer 7 on its outer wall. The isolation layer 7 protects the internal data transmission lines from the influence of the external electromagnetic environment. The design of the isolation layer 7 takes into account efficient shielding performance, lightweight and compatibility, ensuring that the optical cable can work stably in complex electromagnetic environments and preventing signal interference.

[0034] The isolation layer 7 significantly improves the anti-interference capability of the optical cable, ensuring stable operation even in complex electromagnetic environments and protecting the internal data transmission lines from external electromagnetic interference. The design of the isolation layer 7 does not affect other functions and structures of the optical cable, making it suitable for various application scenarios, especially for occasions that require operation in complex electromagnetic environments.

[0035] As a preferred option, such as Figure 1 and Figure 3 As shown, the optical fiber 2 is also coated with a waterproof coating 8 to protect the optical fiber from the effects of a humid environment and effectively prevent moisture intrusion.

[0036] The waterproof coating 8 significantly improves the waterproof performance of the optical cable, ensuring stable operation in humid environments, protecting the optical fiber from moisture, and preventing signal attenuation and optical fiber aging.

[0037] As a preferred option, such as Figure 1 and Figure 3 As shown, the low-smoke halogen-free flame-retardant polyolefin outer sheath 1 has an anti-ultraviolet coating 9 on its surface to protect the optical cable from ultraviolet radiation and extend the service life of the optical cable.

[0038] The UV-resistant coating significantly improves the weather resistance of optical cables, preventing UV radiation from causing aging and damage to the cable materials. It avoids mechanical performance degradation and signal attenuation caused by material aging, making it suitable for various application scenarios, especially for occasions requiring long-term outdoor exposure.

[0039] As a preferred option, such as Figure 1 and Figure 3As shown, the low-smoke halogen-free flame-retardant polyolefin outer sheath 1 is made of polyethylene, polypropylene or copolymers thereof, and has excellent mechanical properties, chemical resistance and flame-retardant properties.

[0040] The low-smoke, halogen-free flame-retardant properties significantly improve the safety of optical cables, reduce harmful smoke generated in the event of a fire, and ensure the safety of the laying environment and personnel. Polyethylene, polypropylene, or their copolymers have good flexibility, abrasion resistance, and chemical corrosion resistance, and can provide reliable protection under complex laying conditions, making them suitable for various application scenarios.
