1. Obtain the appropriate tools (portable can of oil-free compressed

air and alcohol pads) from the fiber-optic cleaning kit.

2. Disconnect the fiber-optic cable from the transceiver. Use

compressed air to blow any contaminants from the connector as

described below (see A and B of

Figure 3-6).

— Keep the air nozzle approximately 50 millimeters (two inches)

from the end of the connector and hold the can upright.

— Blow compressed air on the surfaces and end of the connector

continuously for approximately five seconds.

3. Gently wipe the end-face (A) and other surfaces of the connector

with an alcohol pad (B) of Figure 3-6. Ensure the pad makes full

contact with the surface to be cleaned. Wait approximately five

seconds for cleaned surfaces to dry.

4. Repeat step 2 and step 3 of this procedure (second cleaning) and

again (third cleaning), then reconnect the fiber-optic cable to the

port.
