[0002] Single-mode optical fibers have many advantages such as low loss, wide bandwidth, and large information capacity. In recent years, many research departments and manufacturers at home and abroad have been actively researching and developing single-mode optical fiber systems. Correspondingly, the research and application of single-mode optical passive devices have become increasingly important. The x single-mode optical switch with the function of switching optical paths is an important functional device with a wide range of uses. In optical transmission systems, it is mainly used in multi-channel optical monitoring systems, LANs, multi-light source detector switching, and optical sensor multi-point monitoring systems; in optical test systems, it can be used for the testing of optical fibers, optical devices, networks, field engineering optical cables, etc. In addition, it can also be used for the debugging of optical devices.

[0003] A common single-mode optical switch consists of a box body, its internal components, and a mounting bracket. When in use, the single-mode optical switch is first installed in a specified position through the bracket. However, due to the plate structure fixed by bracket bolts, the horizontal position and angle of the single-mode optical switch are fixed after installation, with poor flexibility. When the optical fiber requires a certain installation angle, the fixed bracket cannot be adjusted accordingly, resulting in the possibility of the optical fiber being bent and not meeting the working requirements of the single-mode optical switch. For this reason, a single-mode optical switch is proposed. Content of the Utility Model
