A 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.
