Description

Technical Field

[0002] Optical fiber, a fiber made of glass or plastic, is a crucial component of both optical fiber communications and optical fiber sensing. Fiber optic communications have been developed for decades, and a relatively well-established optical fiber communications industry has emerged in my country. Its advantages, such as low loss, wide bandwidth, and high capacity, have gradually gained favor among industry professionals and are experiencing rapid growth. In the field of optical fiber sensing, optical fiber can serve not only as a path for information transmission but also as a detector for sensing physical parameters, enjoying widespread application.

[0003] Optical fibers are connected to each other through fiber optic connectors and adapters. To protect the fiber optic connections, specific locations are generally set up for unified fiber transfer. Due to the widespread application of optical fiber in various fields, the locations where optical fibers are unified transferred are often very densely packed with optical fiber connectors, adapters, and other components. When a fiber needs to be removed, especially for ST and FC fiber optic connectors that require twisting and moving during assembly and disassembly, the dense layout of the components makes it difficult for workers to find space to remove the fiber. Although optical fibers with different functions are distinguished, workers may still select the wrong target fiber when working in dense fiber areas. The connection between the optical fiber and the optical fiber connector is relatively weak and may break during assembly and disassembly.

[0004] Therefore, it is necessary to develop a portable auxiliary tool for disassembling and assembling dense optical fiber jumpers suitable for connectors that are difficult to disassemble, such as ST and FC. Utility Model Content
