The Clean and Maintenance Method of Optical Fiber
Connector
In many times, we consider the decline of the optical power as the

connector was polluted by dust or dirt. Inspect the fiber connector,
component, or bulkhead with a fiberscope. If the connector is dirty, clean it
with a cleaning technique following these steps:
1. Turn off the device power supply and carefully pull off the optical fiber
connector from the adapter.
2. Wash carefully with good quality lens wiping paper and medical absorbent
alcohol cotton. If use the medical absorbent alcohol cotton, still need to wait
1~2 minutes after wash, let the connector surface dry in the air.
3. Cleaned optical connector should be connected to optical power meter to
measure optical output power to affirm whether it has been cleaned up.
4. When the cleaned optical connector screwed back to adapter, should
notice to make force appropriate to avoid ceramic tube in the adapter crack.
5. The optical fiber connector should be cleaned in pairs. If optical power is
on the low side after clean, the adapter may be polluted, clean it. (Note:
Adapter should be carefully operated, so as to avoid hurting inside fiber.
6. Use compressed air or degrease alcohol cotton to wash the adapter
carefully. When use compressed air, the muzzle aims at china tube of the
