Clean Fiber-Optic Components
Perform this procedure as directed by a service procedural step or
when connecting or disconnecting fiber-optic cables from port optical
transceivers.
The following tools (supplied by service personnel) are required:
• ESD grounding cable and wrist strap.
• Fiber-optic cleaning kit with:
— Oil-free compressed air or HFC-134a aerosol duster.
— Alcohol-soaked cleaning pads.
CAUTION
Wear eye protection when using an aerosol duster.
To clean fiber-optic components use the following steps:
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.
