Analyzing Traces with the Bidirectional Analysis Application (Optional)
196 FTB-700 Series
Creating Bidirectional Measurement Files
The A->B and B->A traces must respect the following criteria:
Note: The information such as the Cable ID and Fiber ID does not need to be the
same in the A->B and B->A files for the application to be able to generate
the bidirectional measurement.
Item To be valid...
Trace Both must be unidirectional files (.trc or .sor files).
Only traces of native format or of Telcordia
(Bellcore) EXFO version 200 format can be
reanalyzed and be used to generate the
bidirectional measurement.
You can open traces of Telcordia (Bellcore)
non-EXFO version 200 format, but you cannot
reanalyze them. However, they can be used to
generate the bidirectional measurement.
Pulse width Must be identical or adjacent for both traces.
Pulses can be considered as adjacent when
(for example, 2.5 s and 10 s are adjacent, because 10
is equal to 2.5 x 4).
Fiber types Use only traces acquired using singlemode fibers.
Acquisition offset Must be set to zero for both traces.
Wavelengths At least one wavelength must be common to both trace
files. Only the wavelengths that are common to both
traces will be used to generate the bidirectional
measurement and will be saved along with the
bidirectional file.
