amplitude-modulated sensor
A type of fiber optic sensor that detects alteration in position, distance, pressure, liquid level or temperature by transmitting light across a gap to a reflector; a change in the light returned to...
acceptance pattern
A curve expressing an optical fiber's total transmitted power as a function of its launch angle at the input.
adapter
1. In optics, the housing, usually cylindrical, that contains the lenses and iris diaphragm of a camera. 2. In fiber optics, a device for coupling two connectors.
armor
A protective jacket added to an optical fiber to facilitate use in harsh environments. Armor usually consists of steel or aluminum and is placed between the fiber and its outer jacket.
attenuation meter
A device used to measure power loss in fiber optic connectors, cables or systems.
attenuation-limited power
In fiber optics, the limitation on performance imposed by the amplitude of a received signal rather than distortion.
attenuator
An attenuator is an electronic or optical device used to reduce the power or intensity of a signal without significantly affecting its waveform or other characteristics. Attenuators are commonly used...
automatic profiling
In fiber optics, the use of a detector to study the range of refractive indices achieved at various wavelengths. This information is calculated electronically to establish the divergence between...
axial slab interferometry
->
slab interferometry
The method for measuring the index profile of an optical fiber by preparing a thin sample that has its faces perpendicular to the axis of the fiber, and measuring its index profile by interferometry.
axial vapor-phase deposition
A vapor-phase oxidation process for fabricating graded-index optical fibers. It differs from outside vapor phase deposition in that the preform is developed radially rather than longitudinally. An...
