Certifying Fiber Optic Cabling
Autotest in Far End Source Mode
7-41
7
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 page 9-3 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.
