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.

Important topics this year were dispersion measurements, both polarization dispersion and chromatic dispersion, and nonlinear optical measurements.
Civcom's 100G DP-QPSK is equipped with an advanced Digital Signal Processing (DSP) unit that eliminates the need for optical compensation in chromatic dispersion, and featuring the lowest power consumption in the optical market today.
These DSP designs are field-proven and provide electrical compensation for chromatic dispersion (CD), polarization mode dispersion (PMD), and nonlinear impairments in the fiber channel.
Dispersion is the largest category and contains two sessions on polarization mode dispersion, and one session each on chromatic dispersion and group-delay measurements on fiber Bragg gratings.
com/research/5bhw8s/highspeed_fiber_o) has announced the addition of the "High-speed Fiber Optics Communications and Chromatic Dispersion Compensation" report to their offering.
chromatic dispersion, polarization mode dispersion, noise) and allows the use of alien wavelengths in research networks over DWDM systems from multiple vendors," said Roeland Nuijts, Optical Network Architect for SURFnet.
The company has the best testing laboratory in fiber optic communications, which is equipped with more than 100 devices for complex measurements during commissioning and start-up of DWDM systems, for the analysis of optical line parameters like chromatic dispersion, polarization mode dispersion (PMD), for transmission quality testing, GbE measuring and many others.
