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.

Note

Do not use compressed air or aerosol air to clean a fiber optic connector.

To clean a recessed ferrule using a swab, do the following.

1.Insert the swab into the adapter as shown in Figure 16 and rub the ferrule tip with the swab.
