• Measurement Total of Events
The total values of detected events are displayed.
Distance from the measurement start
point (S) to the measurement end point (E)
Total return loss
Total loss
(cumulate loss)
Loss per kilometer between events
Event Analysis Conditions
You can set event search conditions.
• Splice Loss (Splice/Connection)
The instrument recognizes that an event has occurred when it detects a measured result that is
greater than the specified value.
• Return Loss
The instrument recognizes that an event has occurred when it detects a measured result that is
less than the specified value.
• End of Optical Fiber
The instrument recognizes that an end-of-fiber (E) event has occurred when it detects a
measured result that is greater than the specified value.
• Bending Loss
You can select whether to detect bending losses. If you select to detect bending loss, the
instrument recognizes that an event has occurred when it detects a measured result that is
greater than the specified threshold.
• Near-end Dead Zone Prevention (Launch Fiber Setting)
To prevent near-end reflections, if a launch fiber is connected to the measurement start point, the
length of the launch fiber is automatically corrected in the calculations.
For details on near-end dead zone prevention, see “Dead Zone” in section 1.3.
• Splitter Loss
If splitters are inserted, you can select whether to detect the losses caused by them. If you select
to detect splitter loss, the instrument recognizes that an event has occurred when it detects a
measured result that is greater than the specified threshold.
