Cleaning Single Connectors - Avaya 4900 Series Manual

Danger:
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, if 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 contamination 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 you are to damage the
connector.
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 action 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.
Perform this procedure if you suspect more than dust contamination.
Before you begin
• 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.
Danger:

When you inspect a connector, ensure that light sources are off. The light source used in fiber
optic cables can damage your eyes.
To avoid getting debris in your eyes, wear safety glasses when you work with the canned air
duster.
