Table 9. Settings for OTDR Tests
Module
Select the OptiFiber Pro module you will use.
To select a different module, tap the Module panel on the
TEST SETUP screen, then tap a module.
Test Type
When you turn on the tester, the Test Type shows the test
that was last selected.
Auto OTDR: The tester automatically selects settings that
give you the best view of the events on the cabling. This
mode is the easiest to use and is the best choice for most
applications. To see the settings the tester used for an
Auto OTDR test, tap SETTINGS on the trace screen.
Note
Some unusual faults can cause the Auto OTDR
test to show an unsatisfactory trace. If this occurs,
use the Manual OTDR test to get a better trace.
Manual OTDR: This mode lets you select settings to control
the qualities of the trace. See “Manual OTDR Mode” on
page 270 for details.
DataCenter OTDR: This test is optimized for fiber
installations that have short links, many connections, and
the possibility of large reflections.
Notes
By default, the DataCenter OTDR test uses 850 nm
for multimode fiber and 1310 nm for singlemode
fiber. These are the wavelengths typically used in
data centers. You can select other wavelengths if
necessary.
You must use launch compensation when you do
a DataCenter OTDR test.
Manual OTDR
Settings
This item shows only if you select Manual OTDR for the
Test Type. See Table 12 on page 271. Manual OTDR mode
lets you select settings to control the qualities of the trace.
Launch
Compensation
Tap the control to turn the launch compensation function
on or off. See“About Launch and Tail Cords” on page 226.
