Cleaning LC or SC connectors
Clean LC or SC connectors to maintain optimum connectivity between the
end of a fiber cable and its connection or to stop an intermittent transmission
error.
Prerequisites
• You must be familiar with “Safety considerations and best practices”
(page 53).
• With Passport 15000 or 20000 FPs, each fiber cable connection either
directly plugs into a transceiver or into an adapter on the faceplate. A dust
cap on the end of a fiber connector, in a transceiver, or an adapter is
synonymous with any form of plug-in protection cap.
• Avoid direct skin contact with the part of the connector, ferrules, or
transceiver being cleaned.
• Protect your eyes with safety goggles during cleaning.
• Work in a well-ventilated area. Use small amounts of cleaning alcohol
and avoid breathing the vapors.
• Once a fiber cable is plugged into an FP, it does not require cleaning until
it is unplugged. A fiber cable connector must be cleaned immediately
prior to plugging it into an FP or a test device.
• Refer to the figures “LC fiber connectors” (page 288) and “SC fiber
connector” (page 289). The ferrule and endface of an LC connector is the
same shape as an SC connector but is a different diameter.
• The ferrule is the rigid stem at the connector that contains the optical
fiber. Only clean one ferrule at a time. Wear vinyl gloves to avoid
contaminating the ferrule or the cleaning cloth with skin oil.
• Clean the transceiver (or adapter) before cleaning the connector that was
or is to be plugged into it. See “Cleaning the bore of a transceiver”
(page 293).
