To some extent, the performance of the optical fiber connector directly affects the stability and reliability of signal transmission.

[0007] As a further further scheme of the present application: the outer side of the second connecting port is provided with a fine thread, which is matched and connected with the lock nut.

[0008] As a further further scheme of the present application: the height of the lock nut is consistent with the height of the plug.
