To Clean Optical Connectors

Warning:



Do not apply power to this equipment if the fiber is unmated or unterminated.

Do not stare into an unmated fiber or at any mirror-like surface that could reflect

light emitted from an unterminated fiber.
Use safety-approved optical fiber cable to maintain compliance with applicable

laser safety requirements.
Important: Ensure that no optical power is present prior to this procedure.
1 Turn optical power off to the connector.
2 Using an optical connector scope, inspect the connector for scratches, burns, or
other signs of damage.
Note: If the connector is damaged, replace the jumper.
3 If the connector requires cleaning, swipe it across the face of the appropriate
ferrule cleaner several times. This will remove dust and some films.
Note: You may hear a slight "squeak" while cleaning the connector, indicating
that it is clean.
4 Inspect the connector again. If the connector requires further cleaning, clean it
using 99% isopropyl alcohol and a lint-free wipe.
5 Swipe the connector across the face of the appropriate ferrule cleaner several
more times to remove any film left by the alcohol.
6 Repeat all the steps above as needed until the connector is clean.
