5.2 Cleaning optical connectors
An optical connector is basically a lens, and its performance can be degraded by
dust particles, finger grease and scratches.
The surface of connector ferrule can be inspected by means of a microscope.
To clean an optical connector

then clean and dry it carefully with a soft tissue, using a circular movement.
Always use one tissue per cleaning activity.

4. Before re-inserting the connector, clean the adapter by applying a drop of
cleaning liquid to the centre hole and removing it immediately, using a
clean, dry air source.

physical contact with fingers or any other object or surface.
