Types of Events Reported
Reflective Event
Reflection from an unsaturated splice point, such as a Fresnel
reflection caused by a mechanical splice or connector.
Non-Reflective Event
Non-reflective events include such low loss events as fusion
splices and macrobends.
Grouped Event
Events spaced too close to each other for Analysis to
distinguish them as separate events are reported as Grouped
events. Individual reflective events within a Grouped event
may be reported separately in the Event table as sub-events as
shown in Figure 4-17.
