How to clean connectors
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.
Polishing a connector 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.
WARNING Never look into the end of an optical cable that is
connected to an active source.
