If the current fiber design supports multiple modes their characteristics can be
calculated the following way:
| Step | Action |
| 1 | In the “Modes” dialog box recalculate and select the higher-order mode of interest. In that example of a typical 65/125 multi-mode graded-index fiber it is LP(3,6) |
Click the “High Order Mode” icon in the Navigator pane. The “Properties of High Order
Mode” dialog box appears.
It offers the choices to calculate (scan) the characteristics of the selected mode vs.
the wavelength, the proportionally reduced/expanded profile width, etc. After the
calculation the results are displayed in the same view tabs described above.
