Explanation
Real-time Measurement
Measurement conditions are set before the actual measurement takes place, but during real-time
measurement you can change the measurement conditions and adjust markers and the cursor. When
you stop the measurement, the AQ1200 returns to the previous screen.
• In Simple (Full-Auto) mode, you can only change the wavelength.
• You cannot change the attenuation if the averaging mode is set to Hi-Reflection. For details, see
section 3.5.
• The first wavelength that has been set in the Multi WL mode measurement conditions is the
default wavelength in real-time measurement (this applies only to the AQ1200A).
• The wavelength on the AQ1200B is 1625 nm.
• The wavelength on the AQ1200C is 1650 nm.
Installation Completion Notification
Move the cursor to a position a little after the installation point before you perform real-time
measurement. If the fiber end detection position is the same as the cursor position when you perform
real-time measurement, the AQ1200 displays a message on the screen or sounds an alarm. For
details, see section 3.8.
Fiber end
Move the cursor to a position that is a little
after the installation point.
(Example: When the planned installation
point is at 30 km.)
You can perform measurements efficiently by moving the cursor to a position a little after
the installation point (depending on how fast fiber will be installed). This is because the
AQ1200 notifies you of the work completion, which is your sign to measure the connection
loss at that point (splice, connection, etc.).
If work completion notification is turned on, “CheckPoint”
is displayed at the cursor.
