Note: Make sure you don’t touch the soft end of the cleaning tip.

6. Clean the ferrule in the connector port as follows:

6a. Deposit one drop of isopropyl alcohol on a lint-free wiping cloth.

6b. Gently wipe the connector and ferrule.

6c. With a dry lint-free wiping cloth, gently wipe the same surfaces to

ensure that the connector and ferrule are perfectly dry.

microscope(for example, EXFO’s FOMS) or fiber inspection
probe(for example, EXFO’s FIP).

Avoid contact between the tip of the bottle and the wiping cloth,
and dry the surface quickly.
