Interference bands
| Fiber Optic Glossary |
Measured on an interferometer, the dark lines or “bands” optically projected across the face of an object to determine its shape by means of measured elevation

Band, немецкий
That portion of the closure that releases when the closure is removed from a bottle. the band is used for tamper indication.
Band, немецкий
Band, английский
- Is a range of radio frequencies between two defined limits which are used in wireless communications. 800 to 1900 mhz is the band used for cdma.
- Область. интервал. диапазон.
- Пояс; полоса, диапазон (частот); лента
- A range of optical spectrum allocated based on optical amplifiers. six bands are specified by the itu: o (original), e (enhanced), s (short), c (conventional), l (long), and u (ultra). these cover the optical spectrum from 1260 nm to 1675 nm
- N полоса vocal ~s голосовые полосы
- The musicians of a band are called idlers in large ships. also a small body of armed men or retainers, as the band of gentlemen pensioners; also an iron hoop round a

Band brake, английский
- A flexible circular ribbon of steel lined with wooden blocks or asbestos-impregnated material that through a hand or mechanically actuated lever can be brought to bear on the surface of a projecting flange on a hoisting drum, capstan, or wheel and, through friction, control the rotation of the drum, capstan, or wheel.
- External band with friction lining, sometimes used as an additional parking brake, and as a change

Interferometer, английский
- A measurement instrument that projects interference bands across the face of fiber optic connector. the bands are used to determine the centering, angle of apex offset and radius of curvature of the fiber optic connector
- A system containing two or more signals that are combined in phase to cause interference.
- An instrument that employs the interference of lightwaves to measure the accuracy of optical surfaces; it can measure a length in terms of the length of a wave of light by using interference phenomena based on the wave characteristics of light. interferometers are used extensively for testing optical elements during manufacture. typical designs include the michelson, twyman-green and fizeau interferometers.

Splice-on plugs use a prepolished fiber stub and then are, английский
Mechanically or fusion spliced. military, industrial, and heavy-duty specialized connectors may use expanded beam lenses and termini contacts (instead of ferrules) based on standard mil/aero dimensions. key specifications for all connectors include attenuation, reflectance, and repeatability
Extrinsic loss, английский
- Loss caused by imperfect alignment of fibers in a connector or splice such as lateral offset, angular misalignment, end separation, and end finish
- Splice losses arising from the splicing process itself.
