Averaged Bi-Directional Results
Note
Unless otherwise noted, this section applies to
bi-directional results from SmartLoop tests and bi-
directional OTDR tests on single fibers.
Figure 77 shows an EventMap with averaged results from a bi-
directional SmartLoop test.
For averaged results, the tester shows the EventMap and the
event TABLE tabs, but not the OTDR tab. The averaged results do
not include Ghost events.
 For Hidden events, the tester calculates the average loss of
the event that causes the hidden event, then divides that loss
among the events inside the dotted lines. For example, if the
average loss of an event is 0.24 dB, and the event causes one
event to be hidden, then the average results show 0.12 dB for
the event and 0.12 dB for the hidden event.
 For these measurements, the averaged results show the larger
or the worst of the two results:
 Distance between events: larger distance is shown
 Reflectance: worst value is shown (for example, -30 dB is
worse than -40 dB). The reflectance measurements from
the unconnected ends are not used in the averaged
results.
 Segment length: larger value is shown
 Segment attenuation: larger value is shown
 Fiber length: larger value is shown
 Overall loss: average value is shown
 Optical return loss: worse value is shown (for example,
30 dB is worse than 40 dB)
 The Port Connection Quality in the averaged results is the
rating from End 1.
