8.6 Bidirectional OTDR Testing (X-view)
When Bidirectional fiber testing results are available, the OTDR can be used to view the
results using the X-format. The OTDR results table will be unidirectional, meaning results can
be viewed from one trace at a time. Use the green arrow in thumbnail view to switch active
trace/even table results.
In some cases, a more detailed analysis may be needed. This can be
accomplished by averaging the test results of both traces. Results are averaged
to counteract variation in attenuation at connector junctions between fiber
sections.
Fiberizer Cloud or Fiberizer Desktop Plus software is recommended to:
•
Generate test reports that will include the results table that shows both
individual results and averaged bidirectional results, along with traces in
an X-view format.
• Automate bidirectional test reports for a batch of fiber strands, instead of
individual strands at a time.
For more information on Fiberizer Cloud or Fiberizer Desktop Plus, go to
www.veexinc.com or contact Customer Care.
To create a bidirectional X-view screen:
1. Before saving bidirectional test results, configure Autosave settings so that it is easy to
track bidirectional results. In the Setup tab, tap Autosave . The Autosave Parameters
window appears.
• Set
Increment
to Trace ID and
Other
tab to enter Origin and Termination sites.
•
The Trace ID label should reflect the physical location for each direction (e.g. first trace
labelled “origin_end” and the second opposite end labelled “end_origin”).
Do not use “-“ in the Trace ID field.
• Reset or Force the Trace Index counter number to the fiber port you are testing at;
otherwise, it will continue incrementing from the previous test. To change the number,
tap Trace Index .
