Appendix B: Cleaning Fiber Optic Connectors

Using a Swab
Specially treated swabs (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, as shown in Figure 17. 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, do the following.

ferrule tip with the swab.
