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.

Single-mode fiber is the most effective means of limiting modal dispersion since its core diameter is small enough that the fiber propagates only one mode efficiently.
Other multimode fiber optic cabling systems strive to minimize just the effects of modal dispersion, only to eventually become limited by chromatic dispersion.
While these earlier LED-based networks were limited equally by modal and chromatic dispersion, GBE will be affected almost entirely by the modal dispersion since it uses narrow-spectral-width lasers as sources.
