Appendix B: Cleaning Fiber Optic Connectors

Using a Swab
Specially treated swabs, known as stick cleaners, are available for
cleaning inside connector adapters or hard-to-reach ferrule tips. These
swabs, often referred to as “lint free” or “alcohol free” swabs, are available
from many vendors. Examples are shown in Figure 27. Stick cleaners are
available in both 2.5 mm and 1.25 mm sizes for use on SC and MU
connectors respectively.
Note
NEVER use a household cotton swab and/or alcohol to clean a fiber
optic connector. This may leave a residue on the ferrule tip.

Note
Do not use compressed air or aerosol air to clean a fiber optic
connector.
To clean a recessed ferrule using a swab, perform the following
procedure.
1. Insert the swab into the adapter as shown in Figure 26 and rub the
ferrule tip with the swab.
