Abstract :
We derive an equation that relates the differences between the mean transit times of modes of a multimode fibre with loss, multimode dispersion and mode-conversion parameters. The concept of dynamic equilibrium is developed for the temporal difference. Further, we propose a new method of simultaneous measurement of loss and mode-conversion parameters which utilises the temporal difference.
