Fiber cleaning

Steps
Complete the following steps to clean a pluggable optics module.
........................................................................................................................................................................................................................
1
Remove the protective process plug from the pluggable optics module. Keep the process
plug clean until reinstalled later, if required.
When performing this step hold the canned dry nitrogen or air upright. If the canned dry
nitrogen or air is held upside down, inert gas may be released onto the connector surface.
The inert gas leaves contamination on the connector surface that cannot be removed.
........................................................................................................................................................................................................................
2
While holding the canned dry nitrogen or air, position the tip of the nozzle extension as
close as possible, but not close enough to make physical contact, to the sleeve inside the
port receptacle and make three consecutive short blows (approximately one second each).
Repeat this step for the other port.
........................................................................................................................................................................................................................
3
Using the stereo zoom scope, visually inspect the optics module. If required, repeat
up to two more times then go to the next step.
........................................................................................................................................................................................................................
4
If required, insert a CLETOP stick into the transmit (TX) port sleeve until vertical force
can be applied to the fiber stub end surface. Rotate the CLETOP stick five full rounds.
........................................................................................................................................................................................................................
5
Using the stereo zoom scope, visually inspect the optics module. If required, repeat Step 4.

CAUTION
Corrosive substance hazard
NOTICE
This step should only be performed on the transmit (TX) port if the air blows
did not work. Do not perform this step on the receive (RX) port. The receive
(RX) port contains a lens for focusing a wide input. The lens is more easily
scratched than cleaned.
NOTICE
It is recommended that the process plug be installed into the optical ports on
the pluggable optics module to maintain cleanliness until the optical fiber is
connected.
