Test Type
(continued)
FaultMap: The FaultMap test can show connections that do
not show on the OTDR EventMap and connections that are
poor because they have high reflectance. See “The
SmartLoop Test” on page 376.
SmartLoop OTDR (Auto) and SmartLoop OTDR (Manual):
The SmartLoop test lets you connect the far ends of the
two fibers in a link so that one OTDR test gives you results
for both fibers. The Auto and Manual settings operate the
same as for the OTDR test. See “The SmartLoop Test” on
page 376.
FiberInspector: The FiberInspector test lets you use an
optional FI-7000 FiberInspector video probe to inspect the
endfaces in fiber optic connectors. See Chapter 8.
Manual OTDR
Settings
This item shows only if you select Manual OTDR or
SmartLoop OTDR (Manual) for the Test Type. Manual
OTDR mode lets you select settings to control the test
parameters for the trace.
Manual
Settings:
Range
The Range is the maximum distance shown on the trace.
Select the range that is nearest to, but not less than, the
distance to the event you want to examine. If the tester
does not correctly identify the end event, select the next
higher range, then do the OTDR test again.
Auto: The tester selects a range that gives the best possible
view of the events on the fiber. The range is not limited to
the fixed ranges provided.
For the manual SmartLoop OTDR test, the maximum range
setting applies to the longest fiber in the pair, including
the loopback and launch/tail fibers. The maximum settings
are 20 km for multimode and 60 km for singlemode.
