Event Icons
The following table shows an overview of event icon types.
Table 4 Event Icons
Icon Explanation
Start of the fiber
Location at distance of 0 km.
Reflective Event
Reflection from a splice, for example, Fresnel reflection.
Non-Reflective Event
Non-reflective events include such low loss events as fusion
splices.
Grouped Event
Events spaced too close to each other for Analysis to
distinguish them as separate events are reported as
Grouped events.
Far End Event
Far end of the optical fiber under test.
Questionable End Event
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
Dist. Range
before
a far end or break of the optical fiber cable is detected.
Splitter Event
Loss due to fiber splitter.
Macro Bend Event
Event that causes loss difference when measuring multiple
waveforms.
This can occur when excessively bending the fiber.
