Procedure steps
1 If the connector is in use, disconnect it from the function processor (FP).
If the connector is not in use, slide the protective dust cap off the end to
expose the ferrule.
If an inline attenuator is used for the connection at the FP end, the
receptacles of the attenuator and the connectors that plug into it must also
be cleaned according to its manufacturer’s instructions.
2 Holding a can of compressed gas upright, blow into the cavity surrounding
the ferrule. Avoid having propellant fluid coat the connector.
Do not blow onto the ferrule with your breath. Moisture from your breath
will contaminate the surface.
3 Use the plastic squeeze bottle to apply 1 drop of isopropyl alcohol on the
ferrule.
4 While the ferrule is wet, use a new dry TEXWIPE cloth to firmly wipe its
endface and lateral surface. Do not allow the alcohol to dry on the ferrule
because it will leave a residual film on the adaptor. If the ferrule is visibly
dirty, use figure-eight motions when wiping the endface.
Dirt on the ferrule may not be visible to the human eye. Use a new cloth
for each ferrule so that dirt is not transferred from one ferrule to the next.
WARNING
Risk of eye injury by laser
Never look directly into the end of a fiber cable, let an end
pass in front of your eyes, or use an optical device to look
at the end of an optical fiber unless you are certain the
other end is not connected. The laser travelling through a
fiber cable can injure the human retina.
WARNUNG
Gefahr von Augenverletzungen durch Laserstrahlen
Blicken Sie nie direkt auf das Ende eines Glasfaserkabels,
und überprüfen Sie auch einzelne Faserenden nicht mit
einem optischen Gerät, wenn Sie nicht sicher sind, daß das
andere Kabelende nicht angeschlossen ist. Der über die
Glasfasern übertragene Laser kann die menschliche
Netzhaut verletzen.
