Cleaning EUI Connectors
Regular cleaning of EUI connectors will help maintain optimum performance. There
is no need to disassemble the unit.
To clean EUI connectors:
1. Remove the EUI from the instrument to expose the connector baseplate and
ferrule.
2. Moisten a 2.5 mm cleaning tip provided by EXFO with one drop of isopropyl
alcohol (alcohol may leave traces if used abundantly).
3. Slowly insert the cleaning tip into the EUI adapter until it comes out on the other
side (a slow clockwise rotating movement may help).
4. Gently turn the cleaning tip one full turn, then continue to turn as you withdraw
it.
5. Repeat steps 3 to 4 with a dry cleaning tip.
Note: Make sure you don’t touch the soft end of the cleaning tip.
6. Clean the ferrule in the connector port as follows:
6a. Deposit one drop of isopropyl alcohol on a lint-free wiping cloth.
