Description

Technical Field

[0001] The invention relates to the technical field of optical fiber communication, in particular to a tubular storage optical cable device used for optical fiber communication. Background Art

[0002] Communication transmission is divided into wired transmission and wireless transmission. The former has good cable connection reliability, while the latter has a long transmission distance, but is easily affected by terrain, environment, weather, electromagnetic interference, etc., and its stability is not as good as the former. The former has two major transmission media: optical cable and copper cable. Optical cable is mainly composed of optical fiber. Optical fiber is the abbreviation of optical fiber. It is a fiber made of glass or plastic. As a medium for communication signal transmission, it has the advantages of long transmission distance, wide bandwidth, low loss, light weight, strong anti-interference ability, high fidelity, and reliable working performance compared with copper cable. In terms of cost, since the source of materials (quartz) for making optical cables is very rich, with the advancement of technology, the cost is getting lower and lower; while the copper raw materials required for cables are limited, the price will be higher and higher. Therefore, optical cables are more and more widely used in the field of communication technology. At the sending end, the image and information signals to be transmitted are converted into optical signals through electro-optical conversion and transmitted in the optical fiber of the optical cable. At the receiving end, the optical signal is converted into an image and information signal through photoelectric conversion and connected to the application equipment. Therefore, optical fiber is a reliable medium for communication transmission, which can be transmitted over long distances. The optical signal transmitted in the optical fiber is not affected by electromagnetic interference and has a wide range of applications.

[0003] Most existing optical fiber transmissions use fixed optical cable lines, but in emergency scenarios such as first aid, they often rely on extended optical cables containing optical fibers. The optical cables are directly bundled on the laid discs, which are large in size, and optical fiber connectors are added at both ends of the cables. Although the discs are designed with lightweight metal and the weight is reduced, the size remains unchanged, and the cost is high. They need to be laid by special personnel, and due to the size, they can only lay a few kilometers of optical cables, which is slow to lay, and they have to be recycled and reeled after use, which is time-consuming and labor-intensive.

[0004] Therefore, in order to solve the above problems, a tubular storage optical cable device for optical fiber communication is designed, which uses low-cost optical cables or optical fibers to achieve high-density storage, and can lay out the optical cables or optical fibers with simple pulling force without the need for recycling.

[0065] Step 8: After the fixation is completed, the limit rod 8 and the shaft rod 6 are removed in sequence, and the lubricating film 7 is elastically contracted and reset and taken out, thereby completing the high-density storage of the optical cable 3 or optical fiber.

[0066] Step 9: After passing the optical cable 3 or optical fiber extending out of the front end disk 1 through the extension tube 37, the mounting piece 39 of the extension tube 37 is snapped into place with the inner circular groove 40 of the front end disk 1. After the installation of the extension tube 37 is completed, the optical cable 3 is led out from the fiber outlet nozzle 38 and connected to the optical fiber connector 12, and the extended optical cable 3 or optical fiber and the optical fiber connector 12 are fixed with nylon tie through the wire buckle groove.

[0067] Step 10: Connect the fiber optic connector 12 to the optical cable 3 or optical fiber extending out of the rear end disk 2, use the heat shrink tube 13 to heat shrink the exposed optical fiber, fix the bottom sealing plate 41 to the rear end disk 2 by screws 50, and lead the fiber optic connector 12 and the extended optical cable 3 or optical fiber out from the second fiber outlet 46 of the bottom sealing plate 41.

[0068] Step 11: Fix the outer shell 5 of the tubular storage optical cable 3 device to the device that needs to be used, connect the optical fiber connector 12 on the bottom sealing plate 41 side to the optical port of the photoelectric converter, connect the optical fiber connector 12 of the extension tube 37 to the optical port of the photoelectric converter at the other end, and release the limit of the optical cable 3 or optical fiber on the extension tube 37. The optical cable 3 or optical fiber can be quickly deployed by arbitrarily moving the photoelectric converter at one end.
