Cleaning Optical Connectors
General
Intrusions (e.g., dust, grease, etc.) at the interface of two optical fibers, such as at a pair of
coupled connectors, attenuate the signal through the fiber. Consequently, optical connectors
must be clean before they are coupled with other connectors.
Tools and Equipment
Following are tools and equipment required for cleaning connectors.
Dust caps
Caps for protecting the connector from intrusions. A cap is usually made from flexible plastic.
When placing a cap over a connector, avoid pressing it against the fiber ferula surface in the
connector so as to prevent contamination.
Isopropyl alcohol
Solvent for contaminants.
Tissues
Soft multi-layered fabric made from non-recycled cellulose.
Procedure
The procedure for cleaning connectors is as follows:
1. If no stains are present, using a new clean dry tissue, gently rub, in small circular
motions, the exposed fiber surface and surrounding area in the connector to remove
dust.
2. If stains are present, moisten a new clean dry tissue with isopropyl alcohol and gently
rub, in small circular motions, the exposed fiber surface and surrounding area in the
connector to remove the stains.
Using a new clean
dry
tissue, gently rub, in small circular motions, the exposed fiber
surface and surrounding area in the connector to remove the dissolved stains and excess
isopropyl alcohol.
3. If a connector is not to be coupled with another immediately, cover it with a dust cap.
