The Clean and Maintenance Method of Optical Fiber Connector
In many times, we consider the decline of the optical power as the equipment
faults, but actually it may be caused by that the optical fiber 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 adapter, clean the
china tube with compressed air. When use degrease alcohol cotton, insert
directions need be consistent, otherwise can’t reach a good clean effect.
Special notice:
a. In the process of clean the active optical fiber connector, you should avoid
direct shining at eye, which will cause permanence burn!!!!
b. Use proper energy to install the active optical connector, or the ceramic tape
in the adaptor will lead to break. Once the ceramic tape is broken, the
optical output power will decrease rapidly. And turn the active optical fiber
connector slightly, the optical output power changes obviously.
c. Please operate the optical fiber under the condition of shut off the pump
laser. Or the high output power will lead to burn the joint of the optical
output fiber, which will cause the output power decrease.
Changes of the equipment lead to some disagree with this manual, without notice.
