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