Propragation Delay is the measure of the time
required for a signal to advance from one end
of the circuit to the other. When measuring
propagation delay, CertiFiber measures the
round trip delay through both fibers, and then
divides the result by two, assuming that the
cables are equal in length. Propagation delay
cannot be measured on a single fiber; duplex
fibers must be used.
2. To view results for
bidirectional Autotests,
press F1 (Direction) to
switch between the results
measured for each
direction. The arrow in
the titlebar will indicate
the direction in which the
fiber was measured.
3. Use the up and down
arrow keys to scroll to the
bottom part of the
Autotest results screen.
The Job Name, the
Circuit ID, the number of
Connector Pairs and
Splices used for the
Autotest are revealed.
Each test is stored with a
date and time stamp.
4. Use the left- or right-
arrow keys to toggle
between results for Fiber
1 and Fiber 2.
