Managing Bidirectional OTDR Files (FR2-FC Mode)
Creating Bidirectional Measurement Files
You can combine unidirectional measurements into a bidirectional
measurement file. It is possible to use both single-wavelength and
multiwavelength measurements. FastReporter 2 matches the wavelengths.
The A->B and B->A measurement files must respect the following criteria:
To create bidirectional files in FastReporter 2, you must first match A->B
files with B->A files. For information on file matching, see Matching Files
on page 48. Changes made to event matching tolerances will affect
bidirectional event table results.
Item To be valid
Pulse width Must be identical for both measurement files.
Fiber types Use only measurements acquired using
singlemode fibers.
Wavelengths Must be identical for both measurements.
Measurement file Both must be unidirectional files.
