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 62. 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 61 and rub the

ferrule tip with the swab.
