Before cleaning, make sure that the tip of the optical connector cleaner is clean and
free of defects, such as lint, dirt, or other foreign substances.
Using a cleaner with a defective tip might damage the ferrule tip.
Always use a dedicated optical connector cleaner. If you use another type of
cleaner, the ferrule tip might become dirty.

Use the stick-type optical connector cleaner to clear any adhered dirt from the
ferrule end.
