Cleaning of Optical Connector
1. Remove the connector guard cap of optical fiber part, and check the connector end face.
If the end face is not clean, clean it with a reel type fiber cleaner.
2. Push thumb holder of a fiber cleaner and open a cap of the fiber cleaner.
3. When a cap slides and a new cleaning tape comes out, lightly apply the end face to a cleaning tape.
4. Apply the end face of the connector and rotate it (quarter turn four times).
5. Apply the end face to the cleaning tape, and move it to forward direction of a fiber cleaner.
Caution
Do not friction the end face to the cleaning tape. It will cause micro dust or scratch.
6. Take thumb holder off, and close a cap of a fiber cleaner.
7. Check the end face and continue cleaning if necessary.
Removal of Micro Dust
Remove micro dust on the optical fiber part following the method below if necessary.
1. Wipe the optical fiber part with ethanol or cleaning fluid.
2. Softly and slowly wipe the optical fiber part with cleaning fabric.
3. Wipe with a new cleaning stick in the same fashion, and dry the optical connector.
Caution
• Do not use fluid such as bleach because it will damage optical coupling.
• Use ionizer when cleaning in order to avoid the ESD damage to SFP module / SFP+ module.
• SFP module cannot be washed with water. Do not use or clean SFP module / SFP+ module in a
wet space such as bathroom or kitchen.
• Carefully treat SFP module / SFP+ module as it sometimes becomes very hot.
Precautions
• Do not use alcohol, spray, and cotton swab for cleaning of optical connector other than special optical connector
cleaner because dust on the end face of the optical connector plug may not be completely wiped off and more dust
may adhere.
• Immediately connect optical connector to the switch after cleaning. Dust will adhere when the optical connector is
left unconnected.
• Keep the connector guard cap fixed before using SFP module / SFP+ module in order to avoid contamination.
• When SFP module / SFP+ module is contaminated, check end face and clean only if necessary.
• If a lot of fluid is used, it will possibly be accumulated or leak out because SFP module / SFP+ module is not
hermetically closed.
