• The information bar with:
– module reference
– number of acquisitions used for the statistics (Acq)
– wavelength range (1525-1610 nm),
– fiber number (N:)
– fiber length in defined unit
– date and time of acquisition.
– file name (if result stored in memory)
– Pass/fail indication
• The FFT curve and its gaussian shape (for strong mode coupling only).
• the table of results: PMD delay and coefficient, second order PMD (PMD2) delay
and coefficient. This table is different if statistic measurement is selected (see
"Statistics results" on page
The results are displayed in black when no alarm is defined, in green if alarms are within
the threshold defined in the Setup menu and in red if the alarms exceed the thresholds
defined.
