OTDR 127
B Description of Event Types
This section describes all types of events that may appear in the events
table generated by the application. Here is a guide to the descriptions:
³ Each type of event has its own symbol.
³ Each type of event is represented by a graph of a fiber trace, which
illustrates the power reflected back toward the source as a function of
distance.
³ An arrow points to the location of the event type in the trace.
³ Most graphs show one complete trace; that is, an entire acquisition
range.
³ Some graphs show only a portion of the entire range to view events of
interest more closely.
Span Start
The Span Start of a trace is the event that marks the beginning of the fiber
span. By default, the Span Start is placed on the first event of a tested fiber
(typically the first connector of the OTDR itself).
Span End
The Span End of a trace is the event that marks the end of the fiber span. By
default, the Span End is placed on the last event of a tested fiber, and is
called the end-of-fiber event.
You can also make another event the end of the span you want to focus
your analysis on. This will set the end of the events table at a specific event
along the trace.
