Canned compressed air with extension tube
CAUTION
To avoid contamination, optical ports should only be cleaned when
there is evidence of contamination or reduced performance, or
during their initial installation.
To prevent oil contamination of connectors, do not use commercial
compressed air or house compressed air in place of canned
compressed air.
Do not allow the air extension tube to touch the bottom of the
optical port.
Cleaning single SC and FC connectors
Clean connectors so that the optical signal is minimally attenuated by the
connector.
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 pad or a
wipe dampened with optical-grade isopropyl alcohol.
3
Gently wipe the cylindrical and end-face surfaces with a dry, lint-free
tissue.
4
Dry the connector surfaces by applying canned air or letting them
air dry.
To prevent contamination, do not touch the connector surfaces after
cleaning; and cover them with dust caps if you are not going to use
them right away.
