Cleaning Optical Ports

CAUTION: Before conducting the following procedures be certain the instruments are turned Off. Disconnect the external supply from the FLS 101.

Optical ports must be kept free from dirt or other contaminants to ensure accurate measurements and operation. Always clean reference cables before conducting the test procedures outlined in this guide. It is important to keep dust caps in place when instruments are not being used.

For cleaning connector end faces on the FLS 101 light sources, test reference cables, and in fiber frames or adapters, use optical quality cleaning fluid and molded cleaning tips.

For cleaning the FPM 101 optical ports and adapter caps, use lint-free optical cleaning wipes and optical quality cleaning fluid such as IPA -Reagent Grade Isopropyl Alcohol 99% or better) and a can of filtered compressed air.

Cleaning FPM 101 Optical Ports

1.Unscrew the adapter cap from the adapter cap mount.

2.Use lint-free optical cleaning wipes and optical quality cleaning fluid and dampen a portion of the wipe with the cleaning fluid.

NOTE: If using isopropyl alcohol (IPA), be sure to use 99% pure IPA that has not

been contaminated.

3.Gently wipe the exposed FPM 101 port starting with the wet section of the wipe and pulling it to the dry section.

NOTE: Starting with wet cleaning and finishing with dry improves cleaning action,

reduces static buildup, and leaves the end-face dry.

4.Using a can of filtered compressed air (held vertically), blow out any contaminants from the adapter cap.

5.Once the cleaning is complete, replace the adapter cap.
