For a specific excitation condition, the length of multimode optical fiber necessary to attain equilibrium mode distribution.
Note: Equilibrium length is sometimes used to refer to the longest such length, as would result from a worst-case, but undefined, excitation. Synonyms equilibrium coupling length, equilibrium mode distribution length.

That condition in a multimode fiber wherein after propagation has taken place for a certain distance, called the "equilibrium length," the relative power distribution among modes becomes statistically constant and remains so for the course of further propagation down the fiber.
Note 1: In practice, the equilibrium length may vary from a fraction of a kilometer to more than a… (Read More →)

Synonym equilibrium length.

Synonym equilibrium mode distribution.

For an optical fiber, a device or optical system used to create an approximation of the equilibrium mode distribution.

A clock that satisfies the particular needs of equipment and, in some cases, may control the flow of data at the equipment interface.

Intermodulation noise introduced into a system by a specific piece of equipment.

In a building, a centralized space for telecommunications equipment that serves the occupants of the building.
Note: An equipment room is considered distinct from a telecommunications closet because of the nature or complexity of the equipment housed by the equipment room. [After ANSI/TIA/EIA-568A]

The portion of a device that is directly connected to facilities internal to a station, such as the data terminal equipment (DTE) side of the DTE/data-circuit-terminating (DCE) interface, switches, and user end instruments.
