Appendix B: Cleaning Fiber Optic Connectors

62

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 26. 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.

Figure 26. Lint-Free and Alcohol-Free Swabs

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 25 and rub the

ferrule tip with the swab.

Figure 27. Cleaning a Recessed Ferrule

2. If desired, repeat step 1.
