Dispersion

In statistics, the placement of data points along a chart relative to an average or mean line. Dispersion is important to finance as the data points of say, a stock, determine the mean, which in turn helps determines the stock's trend. Dispersion is also used to determine volatility: data points all over the chart indicate that a stock has wild fluctuation in price.

Modal dispersion can be observed in multimode optical fibers, where multiple modes of the same signal pulse propagate at different velocities along the optical fiber and cause pulse broadening.
The modal dispersion for installed runs of multimode fiber with distances in the 200-m to 300-m range can completely close the eye as seen at the system receiver.
Modal dispersion is reduced, and a cleaner optical signal is transmitted.
