Clean and maintenance method of the optical fiber active connector

In many times, we misjudge the decline of the optical power or the reduce of optical receiver

output level as the equipment faults, but actually it may be caused by the incorrect connection

of the optical fiber connector or the optical fiber connector has been polluted by the dust or dirt.

Now introduce some common clean and maintenance methods of the optical fiber active

connector.

1. Carefully screw off the optical fiber active connector from the adapter. The optical fiber

active connector should not aim at the human body or the naked eyes to avoid accidental

injury.

2. Wash carefully with good quality lens wiping paper or medical degrease alcohol cotton. If

you use the medical degrease alcohol cotton, still need to wait 1~2 minutes after wash, let

the connector surface dry in the air.

3. The cleaned optical fiber active connector should be connected to optical power meter to

measure output optical power to affirm whether it has been cleaned up.

4. When screw the cleaned optical fiber active connector back to adapter, should notice to

make the force appropriate to avoid the ceramic tube in the adapter crack.

5. If the output optical power is not normal after cleaning, should screw off the adapter and

clean the other connector. If the optical power still low after cleaning, the adapter may be

polluted, clean it. (Note: Be carefully when screw off the adapter to avoid hurting inside

fiber.)

6. Use the dedicated compressed air or degrease alcohol cotton bar to clean the adapter.

When use the compressed air, the muzzle of the compressed air tank should aims at the

ceramic tube of the adapter, clean the ceramic tube with compressed air. When use

degrease alcohol cotton bar, carefully insert the alcohol cotton bar into the ceramic tube to

clean. The insert direction should be consistent, otherwise can not reach ideal cleaning

effect.
