- The cause of bandwidth limitations in fiber. in multimode systems, modal dispersion is caused by differential optical path lengths known as differential path delay. for singlemode systems, chromatic dispersion is a combination of material dispersion (caused by the line width of the laser source) and waveguide dispersion (caused by the difference in the speed of light in the core and the cladding of the fiber). another type of dispersion is polarization mode dispersion (pmd), which is caused by random vibration, temperature variations, and bending of the fibers known as birefringence

Standard error of the mean, sx, английский
A statistic which indicates the dispersion or spread of values for a mean of a set of measurements. standard deviation index, sdi. generally used in reports from proficiency testing (pt) surveys to describe how far a pt result is from the target value (tv). an sdi of +2.0 means that the laboratory’s reported result is 2 standard deviations of the group above the target value or mean of the group.
Standard deviation of y about the regression line, sy/x, английский
Also known as standard error about the regression line and standard deviation of the residuals (sres). a statistic calculated as part of linear regression analysis. it is the standard deviation of the differences yi-yi, where yi is the observed value corresponding to xi and yi is the value calculated from the regression equations (yi = a + bxi). this statistic measures the dispersion or spread of the data points about the regression line. in the comparison of methods experiment, its ideal value would be zero. values greater than zero describe the random error between the methods, which is composed of the random error or imprecision from both the test and comparison methods, as well as any matrix interferences that vary from sample to sample.
