Cleaning Optical Connectors
Cleaning Universal Connector Adapter (UCA) Bulkheads and Internal Optical Connector
Caution
• Be sure the unit’s UCA and internal optical connector are clean and
undamaged. Connecting an optical connector to the unit when
contaminated/dirty can cause significant damage to the unit’s optics.
• Never clean the connectors when the unit is turned on.
The following items are required for cleaning:
• Filtered compressed air or dusting gas
• Lint-free pipe cleaners or lint-free swab
• Lint-free towels
• Optical grade isopropyl alcohol or optical grade 200° ethanol (do not use rubbing
alcohol, which contains 30% water)
1. Remove the two adapter mounting screws with the No. 0 Phillips screwdriver. Removing
the adapter will expose the internal optical connector that is fastened to the base plate.
The internal connector and base plate are mounted at the factory and should not have to
be adjusted under normal operating conditions.

2. Clean the internal cavity with a pipe cleaner and alcohol (a rotating motion will yield the
best results). The adapter is a critical component that can provide highly reliable mating
of optical connector, if properly maintained.
3. Gently wipe the back surface of the adapter to ensure a clear mating surface to the base
plate.
4. Using the dusting gas or compressed air, blow the base plate and ferrule.
