Table 2. Fiber Test Settings (cont.)
Setting Description
SETUP > Fiber >
Index of Ref. Source (n)
> User Defined
or
Default
The tester uses the index of refraction (n) defined in the currently selected fiber type (
Default
) or
a value you define (
User Defined
). The default value defined by the selected fiber type
represents the typical value for that fiber type. You may enter a different value if necessary. To
determine the actual value, change the index of refraction until the measured length matches
the known length of a fiber.
Increasing the index of refraction decreases the reported length.

Setting a reference sets the baseline power level for loss measurements. See “About Setting the
Reference” on page 11.
After you set the reference, you can enter the lengths of the reference test cords used. The
lengths are saved with results to meet TSB-140 reporting requirements for fiber test results.
Settings for saving tests See the
DTX Series CableAnalyzer Users Manual
or
Technical Reference Handbook
for details on
preparing to save tests.
