Single mode
| Fiber Optic Glossary |
Containing only one mode. when dealing with lasers, beware of ambiguities because of the difference between transverse and longitudinal modes. a laser operating in a single transverse mode typically does not operate in a single longitudinal mode. a type of low-loss optical waveguide with a very small core (2-9 microns). it requires a laser source for input signals because of the very small entrance aperture. the smallest of the core radius approaches the wavelength of the source. consequently, only a singlemode is propagated.

Mode, английский
- В общем случае, гармоническое колебание в системе. в оптоволокне возможная траектория прохождения светового луча. число мод зависит от длины волны, диаметра сердцевины волокна, числовой апертуры и других параметров.

- For lists, the mode is a most common (frequent) value. a list can have more than one mode. for histograms, a mode is a relative maximum ("bump").
- Мода (в статистике наиболее часто встречающаяся величина признака)
- A term used to describe how the power of a laser beam is geometrically distributed across the cross section of the beam. also used to describe the operating mode of a laser such as continuous or pulsed.
- An electromagnetic field distribution that satisfied theoretical requirements for propagation in a waveguide or oscillation in a cavity (e.g., a laser). light has modes in a fiber or laser. a single electromagnetic wave traveling in a fiber.
- A way of doing things. exposure modes are pre-programmed, user-selectable ways of controlling the readings from the exposure system to meet certain subject or picture conditions. these include aperture-priority mode, shutter-priority mode, program-depth mode, etc. autofocusing modes allow a choice of how the camera/lens will go about autofocusing.
- Мода. статистический термин для описания пика кривой распределения множества данных (т.е. наиболее часто встречающегося класса или значения). множество данных только с одной модой называется унимодальным. множество данных с двумя модами описывается как бимодальное.
- Mid-ocean dynamics experiment.
- In statistics, (a) the most probable occurance in a probability distribution of possible occurances and, if the occurances are ordered, (b) the occurance that is more probable than any nearby occurance. if a distribution contains two modes by the letter definitiona it is called bimodal.

- The manner in which acoustic energy is propagated through a material as characterized by the particle motion of the wave.

Mode conditioning patchcord (mcpc), английский
Designed for gbe and fibre channel links using legacy multimode fibers and vcsel light sources operating at 850 nm. normally it is a pair of duplex jumpers that are installed between the transmission equipment at each end of the fiber link. the transmit side has a short singlemode section “offset” fusion spliced to mmf so the light is coupled outside of the center core defect of the mmf

Mode coupling, английский
- A concept for describing and calculating light propagation in certain situations, e.g. involving nonlinear interactions
- The transfer of energy between modes. in a fiber, mode coupling occurs until equilibrium mode distribution (emd) is reached.

Difference, английский
- Disagreement, inequity, contrast, dissimilarity, incompatibility
- Разница; разность
- An important army term, meaning firstly the sum to be paid by officers when exchanging from the half to full pay; and, secondly, the price or difference in value of the several commissions.
Transverse, английский
- Across. a transverse section is a section across the length of a building or room.
- Поперечный
- Directions in wood at right angles to the wood fibers
- Perpendicular to the keel (athwartship).
- Across the vessel; athwartships. trim - fore and aft balance of a boat.
- Literally, “across,” usually signifying a direction or plane perpendicular to the direction of working.
Longitudinal, английский
- Generally parallel to the direction of the wood fibres.
- Продольный
- Generally, parallel to the direction of the wood fibers.
- Продольный, относящийся к долготе, стрингер
- [1] extending in the lengthwise direction, as distinguished from transverse. [2] said of any fore-and-aft structural member, such as a frame or bulkhead.
- Running lengthwise.
- Along the length of a structure.
- Direction parallel to the long axis of an object and perpendicular to its radius — for example, down the length of a cylinder. compare circumferential; radial; transverse. lot tolerance percent defective (ltpd): the poorest quality, in percent defective, individual lot that is acceptable in a sampling plan. ltpd is the percent defective that will be accepted by the sampling plan at most 10 percent of the time. with such a plan, the producer agrees to supply just enough nonconforming product such the consumer will accept the lot using the agreed to sampling plan and acceptable quality level. compare acceptable quality level. lumen (lm): si photometric unit of luminous flux, weighted according to the photopic vision response. one lumen equals the light emitted by one candela (cd) point source into one steradian (sr) solid angle (1 lm = 1 cd/sr).
