Step 9
Repeat the cleaning process as necessary.
End of Procedure
Wet Cleaning Using Lint-Free Swabs
This section describes wet cleaning techniques using lint-free swabs.
Procedure
Step 1
Make sure lasers are turned off before beginning the inspection.
Step 2
Remove protective end cap and store it in a small resealable con-
tainer.
Step 3
Inspect the connector with a fiber scope. Refer to the
Cleaning
Fiber-Optic Connector Plugs
section.
NOTICE
•
Improper cleaning can cause damage to the equip-
ment. Isopropyl alcohol should be removed com-
pletely from the connector or adapter. Residual liquid
alcohol can act as a transport mechanism for loose
dirt on the endface. If the alcohol is allowed to evapo-
rate slowly off the ferrule, it can leave residual mate-
rial on the cladding and fiber core. This is extremely
difficult to clean off without another wet cleaning,
which is usually more difficult to remove than the orig-
inal contaminant. Liquid alcohol can also remain in
small crevices or cavities, where it can re-emerge
during fiber connection.
•
On female multi-fiber connectors, ensure that no
alcohol gets into the guide pin holes. The alcohol may
come out during mating and could contaminate your
connection.
•
Do not use wet cleaning on E-2000 or F-3000 con-
nectors because the connector can trap the alcohol
and re-contaminate the connector.
CAUTION
Invisible laser radiation may be emitted from disconnected fibers or
connectors. Do not stare into beams or view directly with optical
instruments.
