value and the actual measurement for
each fiber will be displayed as Margin. A
positive margin indicates that the
measured loss was less than the
PASS/FAIL value. A negative margin
indicates a fail, and shows how much the
measurement exceeded the maximum
allowable PASS/FAIL amount.
NOTE
If the overall result is FAIL, the failed parameters will be
marked with a reverse highlight.
During Autotest, CertiFiber measures a cable’s
Loss, Length, and Delay. The results are shown
in the top part of the screen.
Optical Power Loss measures
the signal loss in a cable. A
signal is injected into the fiber
cable by the remote unit.
CertiFiber measures the
received signal to determine
loss. The loss in decibel (dB)
and the margin values are
displayed for both wavelengths.
Length measurements are
derived from the propagation
delay results using the GRI
(Graded Refractive Index) at
the appropriate wavelength.
CertiFiber measures the full
length of the fibers under test.
In the Autotest Results screen,
the length is displayed in
meters or feet depending on
your unit’s setup.
