Analyzing Traces and Events

136 OTDR

Analyzing the Fiber on a Specific Fiber Span

If you want to focus your fiber analysis on a specific fiber span, you can

define events (new or existing) as a span start and/or span end. You can

even define a fiber span for short fibers by placing the span start and the

span end on the same event.

Note: You can set a default span start and end, which will be applied during the

first analysis or reanalysis performed upon trace acquisition.

To set a fiber span:

1. From the main window, go to the Events tab (for existing events) and

tap .

From the main window, go to the Measure tab (for new events) and

tap .

2. For new events, define the span event location by moving marker A

along the trace using the left/right arrows. For more information see

Using Markers on page 83.
