Fiber Optics Dictionary Terms

endoscope
A medical instrument used to view inside the human body by inserting the instrument into a natural or created aperture. The endoscope may use a coherent fiber optic bundle or conventional optics to relay the image to the eye or a television camera....
automatic profiling
In fiber optics, the use of a detector to study the range of refractive indices achieved at various wavelengths. This...
free-space optics
Free-space optics (FSO), also known as optical wireless communication or optical wireless networking, refers to the...
tolerance field
In fiber optics, the annular region between two concentric circles; used to specify fiber cladding and core sizes.
laser
A laser, which stands for "light amplification by stimulated emission of radiation," is a device that produces coherent and...
vapor-phase axial deposition
A process by which high-quality fiber optics are made. See axial vapor-phase deposition.
buffer
1. In fiber optics, a protective material applied as an optical fiber cover that has no optical function. 2. In image...
space-division multiplex
In fiber optics, the condition in which each fiber of a bundle carries a separate channel.
optoelectronics
Optoelectronics is a branch of electronics that focuses on the study and application of devices and systems that use light...
Brillouin scattering
Brillouin scattering is a phenomenon in physics where an incident electromagnetic wave (usually light) interacts with...
normalized frequency
Also referred to as the V number in fiber optics; the normalized frequency is a dimensionless quantity, denoted by the...
photonics
The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The...
hygroscopic
In fiber optics, a material whose properties, usually of transmission, are distinctly affected by the absorption of water...
PIN photodiode
A PIN photodiode is a type of photodetector or semiconductor device used to convert light signals into electrical signals....
fiber optics
The use of thin flexible glass or plastic fibers as wave guides — or "light pipes" — to channel light from one...
cladding glass
In fiber optics, the glass that is found around the glass core of the fiber, and that has a lower refractive index than the...
edge-emitting LED
An edge-emitting light-emitting diode is a type of LED structure where light emission occurs primarily along the edge of the...
silicon photodiode
A silicon photodiode is a semiconductor device that converts light into an electrical current. It is a type of photodetector...
distributed feedback laser
A distributed feedback laser (DFB laser) is a type of semiconductor laser diode designed to emit coherent, narrow-bandwidth...
bandwidth-limited operation
In fiber optics, the limitation on performance imposed by the system bandwidth rather than the amplitude of the signal.
polishing jig
In fiber optics, a device used to polish a biconic plug to a specified length and surface finish. Also called a polishing...
optics
Optics is the branch of physics that studies the behavior and properties of light, including its interactions with matter...
attenuation-limited power
In fiber optics, the limitation on performance imposed by the amplitude of a received signal rather than distortion.
adapter
1. In optics, the housing, usually cylindrical, that contains the lenses and iris diaphragm of a camera. 2. In fiber optics,...
cutoff wavelength
1. In detector technology, the long wavelength at which detector response falls to a set percentage (usually 20 or 50...
stimulated Brillouin scattering
In Stimulated Brillouin Scattering (SBS), an incident photon (usually laser light) interacts with acoustic phonons in a...
double-clad fiber
Double-clad fiber (DCF) is a specialized optical fiber that features two concentric cladding layers surrounding a core. The...
intensified vidicon
A standard direct-readout vidicon tube linked by fiber optics to an intensifier for increased sensitivity.
breakout cable
A breakout cable, also known as a fan-out cable or breakout assembly, is a type of cable that combines multiple individual...
