The optical fiber adapter is a centering connection part for realizing an optical fiber movable connector, is a detachable and movable connection device between optical fibers, and is mainly used for precisely butting two end faces of the optical fibers together so as to ensure that optical signals output by the optical fibers are coupled into receiving optical fibers to the maximum extent. Therefore, to a certain extent, the performance of the optical fiber adapter is good or not, and the performance of the optical transmission system is greatly influenced.

There are various types of fiber optic adapters, such as SC, FC, LC, etc. The LC adapter has wide application due to the advantages of low price, convenient plugging operation, small insertion loss fluctuation, high compressive strength, high installation density and the like.

The optical fiber line is used as a common tool for daily signal transmission of people, and the phenomenon of optical fiber line interruption is inevitable in the use process. At this time, it is necessary to check which position of the optical fiber line is interrupted, and the conventional method for checking the interruption position of the optical fiber line requires that the optical fiber line is firstly pulled out from the previously connected equipment and then inserted into a light-emitting device, and the specific point interruption position is detected in a manner that light can be transmitted in the optical fiber line. The user who has pulled out the optical fiber line knows that the optical fiber line can be pulled out from the equipment only by consuming a great amount of effort, and the pulling out of the optical fiber line is too laborious for each detection.
