Care of fiber optic equipment 17
Cleaning receptacles
Clean connector receptacles or ports so that the optical signal is minimally
attenuated by the connection.
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, 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.
