CAUTION
Wear eye protection when using an aerosol duster.
To clean fiber-optic components:
1. Optical transceivers are ESD-sensitive. Ensure an ESD grounding
cable is connected to the product chassis and your wrist.
2. Disconnect the fiber-optic cable from the optical transceiver as
directed by a customer representative or service procedural step.
3. Use an aerosol duster to blow any contaminants from the
component (part 1 of Figure 4-1 ).
— Hold the duster upright and keep the air nozzle
approximately 50 millimeters (two inches) from the end of the
component.
— For approximately five seconds, continuously blow
compressed air or HFC-134a gas on exposed surfaces and the
end-face of the component.

4. Gently wipe the end-face and other surfaces of the component
with an alcohol pad (part 2 of Figure 4-1 ). Ensure the pad makes
full contact with the surface to be cleaned. Wait approximately
five seconds for cleaned surfaces to dry.
5. Repeat steps two and three (second cleaning).
6. Repeat steps two and three (third cleaning).
7. Reconnect the fiber-optic cable to the optical transceiver.
