Understanding Basic Concepts and Dispersion
Dispersion can be measured in a number of ways: Range – The range of a dataset gives the difference between the largest and smallest value. Therefore, the range only takes the two most extreme values into account and tells nothing about what falls in the middle. Range = (Max. Value – Min. Value)Web

Statistical dispersion tells us how spread out (dispersed) the data points in a distribution are. A low dispersion means the data is clustered close together, and a high dispersion means the data is spread far out. For example, we can use various metrics to measure statistical dispersion of the height of humans.Web

ITU G.653 is a dispersion-shifted fiber (DSF), designed to minimize chromatic dispersion in the 1550 nm window with zero dispersion between 1525 nm and 1575 nm. But this type of fiber has several drawbacks, such as higher polarization mode dispersion than ITU G.652, and a high Four Wave Mixing risk, rendering DWDM practically impossible.Web

In a statistical sense, dispersion has two meanings: first it measures the variation of the items among themselves, and second, it measures the variation around the average. If the difference between the value and average is high, then dispersion will be high. Otherwise it will be low. According to Dr. Bowley, "dispersion is the measure of ...Web

Crossovers and dispersion. A speaker's crossover can have a huge effect on dispersion. Consider a two-way speaker with a 6-inch woofer and a 1-inch tweeter. Using the formula from above, we can calculate that the woofer will get beamy above about 2.3 kHz. If the crossover is at 3 kHz, the dispersion will narrow between 2.3 and 3 kHz.Web

high bandwidth efficiency reveals itself by the low pulse energy threshold, needed for the 1/e width to exceed the sign-inversion dispersion bandwidth (marked in yellow in Figure 2a) at 34 pJ ( 24 pJ measured after the output lens). At the threshold pulse energy at 34 pJ, the bandwidth spans from approx. 1500nm to 2450nm, i.e., 950 nm.Web

Standard deviation is generally the preferred method of calculating Dispersion. This is a measure of the amount of dispersion in a given set of data. If the data has a low standard deviation, that means that the values are closer to the mean of the set, while a high standard deviation means they're more spread out from the mean of the set.Web
