the adapter which was removed to clean the built-in ferrule end-face using the
following steps.
Insert the adapter cleaner to the split sleeve interior of the adapter then move it
back and forth while rotating it in one direction.
Note:
Check the ferrule radius. Use only a f1.25 mm or f2.5 mm dedicated
adapter cleaner.
