Table 12. 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 test parameters for the trace. See “The SmartLoop
Test” on page 376 for details.
DataCenter OTDR: This test is optimized for fiber
installations that have short links, many connections, and
the possibility of large reflections. The maximum range for
this test is 1.2 km for multimode and 5 km for singlemode.
For more details on DataCenter OTDR settings, see
“OptiFiber Pro DataCenter OTDR Specifications” on page
625.
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. If you use only one wavelength, the
Macrobend Detection function will not identify
bends.
You must use launch compensation when you do
a DataCenter OTDR test.
