 Use degreaser or alcohol cotton to wash carefully, after finishing let the surfaces dry for
two to three minutes before reconnecting.
 Cleaned optical active connector should be connected to optical power meter to measure
out optical power, to confirm that it has been properly cleaned.
 When the cleaned optical active connector screwed back to adapter, care should be taken
to avoid damaging the connector with excessive force.
 The fiber active connector should be cleaned in pairs. If optical power is on the low side
after cleaning, the connector on the other end of the fiber may need to be cleaned.
 Use compressed air or degrease alcohol cotton to wash the adapter carefully. When using
compressed air, aim the muzzle at the tube of the adapter to clean off any dust. When
use degreasing alcohol cotton, wiping motion needs to be consistent, otherwise the
connector won’t be properly cleaned
Special notice:
a. In the process of cleaning the fiber optic connector, you should avoid direct exposure to
the eye, which will cause permanent damage!!!!
b. Use proper force to install the fiber optic active connector, or the ceramic tape in the
adaptor will lead to failure. Once the ceramic tape is broken, the output optical power will
decrease rapidly. If you turn the fiber optic active connector slightly, the output optical power
changes obviously.
c. Please operate the optical fiber under the condition of close the pump laser. Or the big
output power will lead to burn the joint of the output optical fiber, which will reduce the
output power.
