1. The window of an optical fiber at which material dispersion is very small.
Note 1: In silica-based fibers, the minimum-dispersion window occurs at a wavelength of approximately
1. 3 m.
Note 2: The minimum-dispersion window may be shifted toward the minimum-loss window, i.e.,
1. 55 m, by the addition of dopants during manufacture. [After FAA]
2. In a single-mode… (Read More →)

Of an optical fiber, the transmission window at which the attenuation coefficient is at or near the theoretical (quantum-limited) minimum.
Note 1: If the losses from various mechanisms are plotted on a single graph as a function of wavelength, the minimum-loss window occurs in the vicinity of the wavelength at which the Rayleigh-scattering attenuation curve and the infrared-phonon-absorption curve intersect.… (Read More →)

A unit of measurement expressed as either holding time or conversation time. [47 CFR Pt.36-A]

The product of (a) the number of minutes-of-use-and (b) the average route kilometers of circuits involved. [47 CFR Pt.36-A]

Abbreviation for medium interface point.

Mobility for IPv6

1. Of a network server, the maintenance of an identical copy of its files in (a) another network server, or (b) a redundant drive in the same server chassis.
Note: Mirroring can be used as a rudimentary backup system for the original files, but is more often used to spread out the access load for popular sites, e.g., Web sites,… (Read More →)

Abbreviation for management information system.
