Cleaning Fixed Connectors
Regular cleaning of connectors will help maintain optimum performance.
Do not try to disassemble the unit. Doing so would break the connector.
To clean fixed connectors:
1. Fold a lint-free wiping cloth in four to form a square.
2. Moisten the center of the lint-free wiping cloth with only one drop of
isopropyl alcohol.
3. Gently wipe the connector threads three times with the folded and
moistened section of the wiping cloth.
4. With a dry lint-free wiping cloth, gently wipe the same surfaces three
times with a rotating movement.

Looking into the optical connector while the light source is active
WILL result in permanent eye damage. EXFO strongly recommends
to TURN OFF the unit before proceeding with the cleaning
procedure.

Alcohol may leave traces if used abundantly. Avoid contact between
the tip of the bottle and the wiping cloth, and do not use bottles
that distribute too much alcohol at a time.

Isopropyl alcohol takes approximately ten seconds to evaporate.
Since isopropyl alcohol is not absolutely pure, evaporation will
leave microscopic residue. Make sure you dry the surfaces before
evaporation occurs.
