Table 2. Fiber Test Settings (cont.)
Setting Description
SETUP > Fiber Loss >
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.
SPECIAL FUNCTIONS
> Set Reference
Patch Lengths
(softkey on the View
Connections screen)
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 test reference cords used. The
lengths are saved with results to meet TIA reporting requirements for fiber test results.
