Care of fiber optic equipment 13
Procedure steps
Step Action
1 Remove dust or debris by applying canned air to the cylindrical
and end-face surfaces of the connector.
2 Gently wipe the cylindrical and end-face surfaces with a tissue
dampened with optical-grade isopropyl alcohol.
3 Gently wipe the cylindrical and end-face surfaces with a dry
tissue.
ATTENTION
Do not let the IPA evaporate; wipe it dry immediately. Alcohols can
leave a residue that is difficult to remove.
4 Dry the connector surfaces by applying canned air.
5 Inspect the connector to ensure it is clean and undamaged.
To prevent contamination, do not touch the connector surfaces
after cleaning; and cover connectors with dust caps if you are not
going to use them right away.

Cleaning duplex connectors
Clean connectors so that the optical signal is minimally attenuated by the
connector.
This procedure is appropriate when more than dust contamination is
suspected.
Prerequisites
• lens-grade, lint-free tissue (for example, Kimwipes)
• optical-grade isopropyl alcohol (IPA) (98% or more pure)
•
high-quality canned compressed air with extension tube
Compressed air must be free of dust, water and oil, or filmy deposits or
scratches on the surface of the connector can result.
•
fiber optic microscope for inspecting connectors
