Cleaning Jumper Connectors
Warning
•
Using contaminated or damaged jumpers can affect the performance of the
unit.
•
Never force an optical connector mating. Some connectors have a ceramic
ferrule that can be easily broken.
Optical cable ends need to be inspected before each mating to ensure they are free of contamination or
damage. An inspection scope such as JGR’s CS400K is required.
If they are contaminated, they must be cleaned. The following items are required.
•
Filtered compressed air or dusting gas
•
Lint-free swabs and lint-free wipes
•
Optical grade isopropyl alcohol (IPA) or optical grade 200° ethanol (
do not use rubbing alcohol
which can contain up to 30% water)
To clean the connectors:
1.
Blow the sleeve with compressed air.
2.
Apply the alcohol to a small area of the lint-free wipe and rub the end of the ferrule over the wet
area.
3.
Wipe the ferrule on a dry area of the lint-free wipe.
4.
Blow the end of the ferrule with compressed air.
5.
Apply the alcohol to a lint-free swab to clean the remaining parts of the connector.
6.
With the other end of the swab, dry the areas cleaned.
7.
Blow the areas cleaned with compressed air.
