[0002] With the continuous development of society and the continuous advancement of science and technology, adapter-related technologies are also constantly improving. Fiber optic attenuators can reduce signal energy to achieve the required optical power range. Fiber optic attenuators reduce fixed light energy through optical fibers with fixed attenuation values ​​to achieve the required optical power range. When in use, optical fibers with fixed attenuation values ​​need to be inserted into ceramic ferrules to make fiber optic fixed attenuators.

[0003] During the current fiber threading process, the optical fiber is generally held and one end of the optical fiber is inserted into the ferrule. During this process, it is difficult to align and insert the optical fiber and the ferrule at one time, and the optical fiber is prone to breakage.
