How to Use the Span Function

The Span function on the TOOLS menu lets you get test results
from a section of fiber that you define. For example, if one
segment had a break and was spliced, you can do an OTDR test on
the entire link, but make the test record show results for only the
spliced segment.
You define the span before you do OTDR tests. The tester gives
you results for only the span until you clear the span settings.
If you will test multiple links of different lengths, and must make
sure that all spans include the end of the link, you can set the
Span Stop location to a point beyond the end of the longest link.

When the Tester Will Not Use Your Span Settings

The tester will not use your span settings if Launch

Compensation is On.
 The tester will not use your span settings if you do a
SmartLoop test because that test always uses Launch
Compensation.
