| dispersion |
The cause of bandwidth limitations in a fiber. Dispersion causes a broadening of input pulses along the length of the fiber. Two major types are: mode dispersion caused by differential optical path lengths in a multimode fiber and material dispersion caused by a differential delay of various wavelengths of light in a waveguide material.

| dispersion |
More correctly known as chromatic dispersion. Dispersion results when light of different wavelengths propagates at different velocities down a fiber span. The result is pulse spreading that is a function of length. Total dispersion is measured in units of ps/nm and the dispersion coefficient of a fiber is in units of ps/nm-km, or pico-seconds per nanometer per km of fiber length.
