3.5 Connecting the DUT
WARNING
Do not look at the optical fiber laser light that you are measuring or point the laser
at another person’s eye. Doing so may cause eye damage or impair one’s health.
CAUTION
• Before connecting an optical fiber to the instrument, make sure that the start-up
initialization process has finished. If a strong light source is input during start-up,
the optical section can be damaged.
• Be sure to clean the tip of the optical fiber’s optical connector before connecting.
• Do not try to forcefully attach the optical fiber’s optical connector with the plug
inserted at a slanted angle. Doing so may damage the instrument’s optical
connector’s components or the connector itself.
• Before connecting the input light, make sure that it does not exceed the
AQ6370D’s maximum rated level. If input light exceeding the maximum rated
level is introduced, the optical section may be damaged.
• Press the optical connector hard against the cleaning surface of the special
cleaner to clean it. If it is not pressed hard against the cleaning surface, it may
not be possible to properly clean the optical connector.
Cleaning the Optical Fiber End Face
1.
Firmly press the connector end face of the optical fiber against the cleaning
surface of the cleaner.
2.
While pressing the end face against the cleaner, turn it once.
3.
While pressing the end face against the cleaner, move it.
4.
Repeat steps 1 to 3.
Note
• If you do not firmly press the connector end face of the optical fiber against the cleaner, the
end face may not be cleaned completely.
• You can purchase an optical fiber connector cleaner from NTT-AT Corporation.
