The DGD distribution plot shows the calculated distribution of DGD values that
corresponds to the selected parameters. This plot can be used to find a combination of
average DGD and sample number that will yield a good distribution.
The SOPMD distribution plot shows the calculated distribution of SOPMD values that
corresponds to the selected parameters.
If the dwell time per point (scan interval) is
≥
1 s, the program monitors the progress of
the emulation. As each point is generated, the status block at the lower left of the screen
shows the DGD and SOPMD, sample number, number of completed cycles, and input
and output DOP. The generated PMD, DGD, and SOPMD distribution plots track the
progress of the emulation. When the emulation is complete, the generated value plots will
match the calculated value plots above them.
For dwell time values >1 s, the WSOP function is also available. Click the “WSOP
Enable” button at the bottom left of the screen before starting the emulation to enable
automatic polarization optimization for the worst-case PMD effect at each DGD value.
For dwell time values <1 s, the WSOP and scan monitoring functions are disabled. The
monitor plots are replaced by a progress bar:
