Panda fiber
| Fiber Optic Glossary |
Panda is a common style of pm fiber, using round and symetrical stress rods on either side of the core to induce polarization.

Fiber, английский
- General term for any long, narrow cell of wood.
- Волокно, нить
- A single optical transmission element characterized by a core, a cladding, and a coating. two common structures, single-mode (with a step-index profile) or multimode (with a graded-index profile) are used for fiber optic communication systems. different variations are made depending on the attenuation, bandwidth, dispersion, wavelengths, and mechanical requirements
- Us same as fibre
- Волокно
- [1] any substance (such as cotton, flax, or hemp) that can be separated into threads and twisted or braided together (i.e., to make rope). [2] the word has other meanings in anatomy (nerve, muscle, or connective tissue), botany (slender, threadlike root), nutrition (bulk, dietary fiber, roughage), optics (optical fiber), and as a character trait (moral fiber).

- Term for a unit of any natural or synthetic textile raw material used for manufacturing fabric.
- Термин для единицы любого натурального или синтетического текстильного сырья, используемого для производства ткани.
- A unit of matter, either natural or manufactured, that forms the basic element of fabrics and other textile structures. a fiber is characterized by having a length at least 100 times its diameter or width. the term refers to units that can be spun into a yarn or made into a fabric by various methods including weaving, knitting, braiding, felting, and twisting. the essential requirements for fibers to be spun into yarn include a length of at least 5 millimeters, flexibility, cohesiveness, and sufficient strength. other important properties include elasticity, fineness, uniformity, durability, and luster. (also see manufactured fiber and natural fiber.)

Fiber (fibre), английский
- The characteristic of wrought metal that indicates directional properties and is revealed by the etching of a longitudinal section or is manifested by the fibrous or woody appearance of a fracture. it is caused chiefly by the extension of the constituents of the metal, both metallic and nonmetallic, in the direction of working.
- The pattern of preferred orientation of metal crystals after a given deformation process, usually wiredrawing.

Fiber amplifier, английский
- Most common are the erbium doped fiber amplifiers (edfas), semiconductor optical amplifiers (soas), and raman amplifiers, which are used to increase signal gain without electrical conversion
- An optical fiber doped to amplify light from an external source. the most important type is the erbium-doped fiber amplifier.

Fiber architecture, английский
The spatial arrangement of fibers in the preform. each architecture has a definite repeating unit.
Fiber axis, английский

Fiber bandwidth, английский
The lowest frequency at which the magnitude of the fiber transfer function decreases to a specified fraction of the zero frequency value. often, the specified value is one-half the optical power at zero frequency.
Fiber bed filter, английский
Fiber bonding (binding), английский
Fiber bragg grating (fbg), английский
- A piece of photo-refractive fiber that is exposed to highintensity uv interference patterns, causing it to reflect a specific wavelength while being transparent to all other wavelengths. used as a filter in wdm systems
- An optical fiber in which the core refractive index varies periodically, causing bragg scatting at wavelengths selected by the period and refractive index. a fiber bragg grating reflects the selected wavelength and transmits others.
Fiber bragg gratings, английский
Reflective structures in the core of an optical fiber with a periodic or aperiodic perturbation of the effective refractive index
Fiber cables, английский
Cables containing one or several optical fibers

- Поляризация
- A characteristic of the electric field on an electromagnetic wave in space. the directional aspects of a signal. signals can have circular or planar polarization. four types of polarization are used with satellites; horizontal, vertical, right-hand circular and left-hand circular. electromagnetic waves have the ability to vibrate in different radial directions. typically, satellite signal polarization is either horizontal or vertical. the signal coming from the satellite to the dish will either be vibrating along a horizontal or vertical plane. the receiving equipment must be adjusted to receive the correct polarization.
- Vibration of the electric field vector in specific direction perpendicular to the direction of propagation of the wave. also, restriction of the vibrations of the electromagnetic
- Alignment of the electric and magnetic fields that make up an electromagnetic wave; normally refers to the electric field. if all light waves have the same alignment, the light is polarized.
- When light penetrates certain crystals the emergent light is different than the entrance light. the emergent light emitted by the crystal vibrates in only one direction.

Longitudinal modes, английский
Oscillation modes of a laser along the length of its cavity. each longitudinal mode contains only a narrow range of wavelengths, so a laser emitting a single longitudinal mode has a narrow bandwidth. distinct from transverse modes.
