Icon Explanation
Reflective Event
Reflection from an splice such as a Fresnel reflection.
Non-Reflective Event
Non-reflective events include such low loss events as fusion
Grouped Event
Events spaced too close to each other for Analysis to distinguish
them as separate events are reported as Grouped events.
In the event table, the result of the entire group is displayed
at the first event of the group.
Far End Event
Far end of the optical fiber under test.
Events out of dynamic range or out of distance range.
● Out of Range
The trace reaches the noise level before a far end or break
of the optical fiber cable is detected.
● Out of Distance
The trace reaches the end point set for
before
a far end or break of the optical fiber cable is detected.
Splitter Event
Loss due to fiber splitter.
Loss
Displays the event loss.
Reflect
Displays the reflectance or level difference of the reflective event. You
can change this item at
Type of reflective result shown in 4.2.3,
“Preferences (2-2)”.“***” is displayed for non-reflective events. The value
is followed by S if it is not measured properly.
dB/km
Displays the value obtained by dividing “Loss between events” by
“Distance between events”.
