Appendix B: 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 cleaned 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,
A. 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.
B. 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.
C. If a connector is
not
to be coupled with another immediately, cover
it with a dust cap.
