After connecting the
network, the received
optical power of the optical
contact point is unstable
and has large continuous
change. The output RF
signal is unstable, too. But
the detected output optical
power of the optical
transmitter is normal.
The optical fiber active connector
types do not match, maybe the APC
type connect to PC type, make the
optical signal cannot normal
transmission.
The optical fiber active connector or
adapter may be polluted seriously or
the adapter has been damaged.
1. Check the type of optical fiber active
connector and adopt the APC type optical
fiber active connector to ensure the normal
transmission of optical signal.
2. Clean the polluted optical fiber active
connector or adapter. Specific operation
methods see “Clean and maintenance method
of the optical fiber active connector”.
3. Replace the damaged adapter.
10. 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 pull 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 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 connect 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 pull 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 pull 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.
