Appendix D: Cleaning Fiber Optic Connectors
206
Using a Swab
Specially treated swabs (stick cleaners) are available for cleaning inside
connector adapters or hard-to-reach ferrule tips. Shown in Figure 122,
these swabs, often referred to as “lint free” or “alcohol free” swabs, are
available from many vendors. 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.

connector.
To clean a recessed ferrule using a swab, perform the following
procedure.

ferrule tip with the swab.
