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.
Warning:
Risk of eye injury
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.
To avoid eye irritation on contact, wear safety glasses when you work with isopropyl
alcohol.
Procedure
1. Remove dust or debris by applying canned air to the cylindrical and end-face
2. Gently wipe the cylindrical and end-face surfaces with a tissue dampened with
