Visually inspect the connector to determine cleanliness and to determine if it needs replacing. You
must replace a connector that has a scratch across the core, or a scratch that appears to end in the
core.
The proper connector cleaning method depends on the connector contaminants:
• Judge cleanliness by visual inspection with a fiber microscope. First inspect the connector, and
then clean as required.
Warning:
Risk of eye injury
When you inspect a connector, ensure that light sources are off. The light source in fiber
optic cables can damage your eyes.
• If you suspect only the possibility of dust particles (for example, which can occur when you
leave a connector uncapped in a clean environment), use high-quality canned air or a reel
cleaner, for example, a Cletop, to clean the connector. A reel cleaner is a good choice to
ensure that no dust contaminates the connector.
• If the connector is visibly dirty or you suspect it to be contaminated by chemicals (for example,
matching gel), use high-quality alcohol and canned air to clean the connector. This method is
the most thorough cleaning method. In some cases, a reel cleaner can suffice.
The more surface manipulation you apply to the connector, the more likely the connector is to
become damaged.
When you insert a connector ferrule into a connector or adapter, ensure that the ferrule tip does not
touch the outside of the mating connector or adapter. This can produce scratches and dirt deposits
on the connector.
To help prevent connectors from collecting dust, cover them when not in use. To avoid the transfer
of oil or other contaminants from your fingers to the end face of the ferrule, handle connectors with
care. Do not touch the connector end face.
Cleaning single connectors
Clean connectors so that the optical signal is minimally attenuated by the connector.
This procedure is appropriate when you suspect more than dust contamination.
Prerequisites
• You need a lens-grade, lint-free tissue,for example, Kimwipes.
• You need an optical-grade isopropyl alcohol (IPA) (98% or more pure).
• You need a 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.
• You need a fiber optic microscope to inspect connectors.
