Description

Technical Field

[0001] The utility model relates to the technical field of optical cables, in particular to a high-strength, extrusion-resistant composite optical cable. Background Art

[0002] High-strength extrusion-resistant composite optical cable is a composite optical cable with high strength and extrusion resistance. It is composed of a variety of materials, including optical fiber, metal or non-metallic materials, etc. It has good tensile strength and compressive resistance, and can maintain stable optical transmission performance in extreme environments. High-strength extrusion-resistant composite optical cable is widely used in various environments, such as communications, electricity, military, etc. It is used as a transmission medium for optical fiber communication systems and can provide high-speed, high-bandwidth data transmission capabilities. The manufacturing process of high-strength extrusion-resistant composite optical cable is complex and requires the use of high-tech materials and technologies. It usually adopts a multi-layer structure design, including optical fiber layer, reinforcement layer, sheath layer, etc. to provide better protection and support. In addition, it also needs to undergo strict quality control and testing to ensure its reliability and stability in extreme environments. In short, high-strength extrusion-resistant composite optical cable is a composite optical cable with high strength and extrusion resistance. It can maintain stable optical transmission performance in extreme environments and is widely used in communications, electricity, military and other environments.

[0003] According to the retrieval of China Invention Publication No.: CN112327440A, a high-strength, extrusion-resistant composite optical cable is disclosed. The present invention can disperse and buffer the force when subjected to external force extrusion, thereby improving the strength of the optical cable and effectively protecting the optical fiber core. The spiral shape of the inner side of the force-dividing layer matches the first spiral groove, and the force-dividing layer is fixed to the outer wall of the inner sheath body through the first spiral groove, which can prevent the force-dividing layer from sliding on the outer wall of the inner sheath body. The force-dividing layer is spiral, and when the spiral structure is subjected to force at the side, the force will be dispersed to both ends along the spiral outer wall, which can play a role in force distribution, and the spiral structure can play a role in preventing bending, which can effectively protect the optical fiber core. The second spiral groove and the spiral shape of the outer side of the force-dividing layer, the fixed sleeve is fixedly installed on the outer wall of the force-dividing layer through the second spiral groove, which can effectively prevent the fixed sleeve from sliding on the outer wall of the force-dividing layer, and the elastic block plays a buffering role. When squeezed, it can reduce the force received, which can effectively protect the optical fiber core.

[0004] However, there are some issues that need to be considered when implementing the above technical solutions: first, the optical cable sacrifices flexibility while enhancing strength, which makes it easy to be damaged during installation and operation; second, the optical cable is designed to be an integral whole, and the force will be directly transmitted to the optical fiber, which can easily cause the optical fiber to break and be affected by battery interference.

The filling particles 304 are tightly fitted with the inner silicone layer 301, the partitions 302 and the outer silicone layer 303. The polyurethane filling particles 304 can absorb impact and vibration. When the optical cable is subjected to external force, the filling particles 304 change their distribution state and fully unload the force.

[0028] Specifically, a fiber layer 305 is provided on the outside of the outer silicone layer 303. The fiber layer 305 is made of Kevlar material. The fiber layer 305 fits tightly to the outer silicone layer 303. Kevlar fiber is a high-performance synthetic fiber.
