[0002] With the continuous development of optical fiber for information communication, optical fiber arrays have been increasingly used as a main method for image information transmission. In addition, the transmission rate of optical transceiver modules is getting higher and higher, and the integration of devices is getting higher and higher. The requirements for the size and precision of subassemblies are also constantly increasing. When the optical fiber array is installed on the machine, crosstalk caused by the phenomenon of unstable installation angle adjustment (i.e., the scattering and reflection between the light beams emitted by two adjacent optical fibers affect each other) is prone to occur, which will have a certain impact on the performance of the optical fiber array. Moreover, if the optical fiber array is pulled during use, it is easy to cause the optical fiber to break, which is not conducive to the protection of the optical fiber array. Utility Model Content
