If the current fiber design supports multiple modes the characteristics of a group of
modes can be calculated for comparison:
| Step | Action |
| 1 | In the “Modes” dialog box recalculate and select the group of modes, in this case all the modes from LP(0,1) to LP(2,6) |
| 2 | Then proceed to the “Properties of High Order Mode”. Its left-side controls are now disabled and the “Multiple Mode Scan” is checked as the parameter of this calculation is the mode itself, instead of some technological figure of the fiber. |
The user can also choose to sort the results according to the initial sequential number
of the mode in the selected group…
…or according to the effective refractive index in descending order.
