FIXED LENGTH: The tester does not change any parameters
for measurements, even if the trace changes. (The tester
possibly adjusts the resolution and range at the beginning of
the test for a faster test.) This mode helps you stay zoomed-in
on an event when the fiber changes.
If a large change in the fiber length occurs, change to AUTO
LENGTH mode, then change to FIXED LENGTH mode again.
To use the real time trace
1 Clean and inspect the connectors on the launch and tail cords
and the fiber to be tested.
2 Connect the tester to the link as shown in Figure 167 or 168.
3 On the home screen, tap the TOOLS icon then tap Real Time
Trace.
4 In the SELECT A WAVELENGTH popup, select a wavelength

wavelength that gives the best dynamic range and the
smallest dead zones for the link.
