Care of fiber optic equipment 15
Prerequisites
• optical-grade isopropyl alcohol (IPA) (98% or more pure)
• cleaning swabs (also called cleaning sticks or wands)
•
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.
CAUTION
Risk of equipment damage
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, use only high-quality
canned compressed air.
Do not allow the air extension tube to touch the bottom of the
optical port.
Procedure steps
Step Action
1 Remove dust or debris by blowing canned air into the optical port
of the device using the canned air extension tube.
2 Clean the optical port by inserting a wand moistened with alcohol
into the receptacle and rotating it.
Each cleaning wand should only be used to clean one optical
port.
3 Dry the optical port by inserting a dry wand into the receptacle
and rotating it.
ATTENTION
Do not let the IPA evaporate; wipe it dry immediately. Alcohols can
leave a residue that is difficult to remove.
4 Remove any lint by blowing compressed air into the optical port.
5 Reconnect the optical connector and check for proper function.
If you are not reinstalling the connector, be sure to use a
protective cap.
If problems persist, ensure that the connector or receptacle are
not damaged.
