Certifying Fiber Optic Cabling
Autotest in Far End Source Mode 5
5-37
A Overall results for the fiber:
B Loss (Remote -> Main): Overall loss on the fiber
connected between the tester’s output and
input ports. E is PASS, F is FAIL.
C The overall result for the loss measurement.
D The measured loss for the fiber.
Note
If loss is negative, set the reference again and
retest the cabling. See Chapter 7 for more
information on negative loss.
E The maximum loss allowed by the selected test limit.
F The difference between the limit and the measured loss.
Margin is negative if the loss exceeded the limit.
G Meter for the loss measurement. Values in the red zone exceed
the selected test limit.
H Press L View Ref. to view the reference information.
Note
In Far End Source mode, the results do not show a PASS/FAIL
result, limit, or margin if the selected test limit calculates loss
based on fiber length. An example of such a limit is the TIA-
568B Fiber Backbone limit. The tester does not measure
length in Far End Source mode.
