Cleaning connectors is difficult as the core diameter of a single-mode
fiber is only about 9 µm. This generally means you cannot see streaks
or scratches on the surface. To be certain of the condition of the surface
of your connector and to check it after cleaning, you need a microscope.
In the case of scratches, or of dust that has been burnt onto the surface
of the connector, you may have no option but to polish the connector.
This depends on the degree of dirtiness, or the depth of the scratches.
This is a difficult procedure and should only be performed by skilled
personal, and as a last resort as it wears out your connector.
