the test in the test step comprises end face detection, insertion return loss test and end face reinspection in sequence;
the end face detection comprises the following steps:
turning on the power supply of the end face inspection tester and the monitor;
checking whether residual glue exists on the surface of the ferrule column body, if so, removing the residual glue, and cleaning the ferrule column body with alcohol;
inserting the ferrule into an adapter hole of a corresponding type of the detector, adjusting the longitudinal distance of a lens of the end detector until the end face of the ferrule magnified 400 times is clearly seen in a monitor screen, checking whether the end face of the ferrule has scratches, pits, bubbles, color spots and the like, and reworking if defects exist;
respectively storing the good inserting core and the defective inserting core;
the insertion return loss test is completed by using an insertion return loss detector;
and the end face rechecking and the end face detection have the same operation method, and whether the confirmed end face of the ferrule end face is damaged in the insertion return loss test is detected again.
