Table 12. Settings for OTDR Tests (continued)
This setting shows only if you select SmartLoop OTDR
Bi-directional
(Auto) or SmartLoop OTDR (Manual) for the Test Type.
Off: The tester does the SmartLoop test in only one
direction.
On: The tester does the SmartLoop test in both directions
and automatically calculates bi-directional averages of loss.
See "Bi-directional SmartLoop Tests" on page 383.
Tap the control to turn the launch compensation function
Launch
on or off. See"About Launch and Tail Cords" on page 319.
Compensation
This setting does not show for the SmartLoop test because
it is always enabled for that test.
On: The tester identifies bends. To identify a loss event as a
Macrobend
bend, the tester compares the event's loss at two
Detection
wavelengths, such as 1310 nm and 1550 nm. If the loss is
(singlemode
more at the longer wavelength and is more than the
only)
macrobend threshold, the tester identifies the event as a
bend. This setting is On by default.
For the Auto OTDR test, the threshold for the loss
difference is 0.50 dB. To use a different threshold, set up a
Manual OTDR test. See "Macrobend Setup" above.
Off: The tester does not identify bends. Bends show as loss
events in the results.
Select the wavelengths you want to use. You can do tests
Wavelength
at one or all of the wavelengths supported by the module
you selected. The FaultMap and FiberInspector tests do not
have this setting.
Chapter 11: The OptiFiber Pro OTDR Module
A bend always causes a FAIL result. If you want a
PASS result for a link that has a bend, turn off
Macrobend Detection.
If you use only one wavelength, the Macrobend
Detection function will not identify bends.
