Modes command

The “Modes” command opens the “Modes” dialog box, where you can perform initial
calculations and select fiber modes to be calculated further.

This command can be accessed from:

  • Simulation menu
  • Modes icon on the Navigator pane:

Optical Fiber - Modes iconFundamental Mode command

The “Fundamental Mode” command opens the “Properties of Fundamental Mode”
dialog box, where you can select calculation options for the fundamental fiber mode.

This command can be accessed from:

  • Simulation menu
  • Fundamental Mode icon on the Navigator pane:

Optical Fiber - Fundamental Mode icon

Higher Order Modes command

The “Higher Order Modes” command opens the “Properties of Higher Order Mode”
dialog box, where you can select calculation options for a higher order fiber mode.

This command can be accessed from:

  • Simulation menu
  • Higher Order Mode icon on the Navigator pane:

Optical Fiber - Higher Order Mode icon

Cutoff command

The “Cutoff” command opens the “Cutoff” dialog box, where you can calculate the
cutoff wavelength for a selected higher mode.

This command can be accessed from:

  • Simulation menu
  • Cutoff icon on the Navigator pane:

Optical Fiber - Cutoff icon

Birefringence command

The “Birefringence” command opens the “Birefringence” dialog box, where you can
enter the fiber birefringence data.

This command can be accessed from:

  • Simulation menu
  • Birefringence icon on the Navigator pane:

Optical Fiber - Birefringence icon

PMD command

The “PMD” command opens the “Polarization Mode Dispersion” dialog box. When the
“Birefringence” command was not previously executed, then the program opens the
“Birefringence” dialog box first and, after performing the birefringence calculations,
opens the “Polarization Mode Dispersion” dialog box.

This command can be accessed from:

  • Simulation menu
  • PMD icon on the Navigator pane:
