Diplexer
| Fiber Optic Glossary |
- A component used to provide two functions, such as multiplexing or filtering optical signals. for example, a diplexer used at an fttx optical network terminal filters the downstream 1490-nm wavelength and multiplexes the upstream 1310-nm wavelength to or from a single fiber
- A device that combines two or more types of signals into a single output. usually incorporates a multiplexer at the transmit end and a demultiplexer at the receiver end.

Multiplexing, английский
- Мультиплексирование
- The process where several analog message signals or digital data streams merge into one signal over a shared medium.
- Transmission of two or more information streams over a single physical medium at the same time such that each data source has its own channel. allows a number of simultaneous transmissions over a single circuit. common methods are frequency division multiplexing (fdm) where the frequency bands are split to constitute a distinct channel and time division multiplexing (tdm) where the common channel is allotted to several different information channels, one at a time.
- The process by which two or more signals are transmitted over a single communications channel. examples include time-division multiplexing (tdm) and wavelength-division multiplexing (wdm).
- Уплотнение (каналов); разделение (каналов); объединение (сигналов); мультиплексирование; мультиплексная передача
- A technique used in communications and input/output operations to transmit a number of separate signals simultaneously over a single channel or line. to maintain the integrity of each signal on the channel, multiplexing can separate the signals by time, space, or frequency. the device used to combine the signals is a multiplexer.
Downstream, русский
Нисходящий (поток). в спутниковой связи: канал от спутника к наземной станции.
Wavelength, английский
- Light is made up of electromagnetic waves; wavelength is the crest (peak)-to-crest distance between two adjacent waves.
- Для оптических сетевых устройств длина волны светового потока составляет 850, 1300, 1310 и 1550 нм
- The optical term for frequency. fiber optics generally uses the 850 nm, 1300/1310 nm, 1550 nm and 1625 nm wavelengths for transmission purpose due to the marriage of performance with light sources, optical fibers, and optical detector technologies

- The length of the light wave, usually measured from crest to crest, which determines its color. common units of measurement are the micrometer (micron), the nanometer, and the angstrom unit.
- The spatial period of a plane wave
- The distance between "waves" in the electromagnetic field, specified as angstroms or nanometers.
- The distance an electromagnetic wave travels in the time it takes to oscillate through a complete cycle. wavelengths of light are measured in nanometers (10-9 m) or micrometers (10-6m).
- The linear distance occupied by one complete cycle of vibration of an energy form from any given point to the next point characterized by the same phase.
- For light waves or sound waves, the distance between two successive points of a periodic wave in the direction of propagation, in which the oscillation has the same phase; the distance the wave travels in one period. for light waves three common units of wavelength are: micrometer, nanometer, and angstrom. wave molding, oundy molding, swelled chamfer, undulating molding, undy

- The physical length between corresponding points of successive cycles of a wave. low frequencies have long wavelengths; high frequencies have short wavelengths.
- The distance between the crests of a wave in a radio signal, measured as the speed of light divided by the frequency in- hz.
- The distance between one peak of a wave and the next peak
- Light is measured by its wavelength (in nanometers) or frequency (in hertz). one wavelength. equals the distance between two successive wave crests.
- The distance between two points having the same phase in two consecutive cycles of a periodic wave, along a line in the direction of propagation.
- Distance between repeating values of a wave — for example, the distance from one peak to the next peak on a sine wave. wavelength is a fundamental descriptor when discussing wave behavior, system sensitivity, and diffraction effects.
- Distance between repeating values of a wave. for example, the distance from one peak to the next peak on a sine wave.
- Distance between repeating values of a wave. for example, the distance from one peak to the next peak on a sine wave. wavelength is generally measured in nanometers when considering uv-a radiation (for example, 365 nm). compare frequency.
- Distance between repeating units of a wave. for example, the distance from one peak to the next peak.
- Distance needed in the propagation direction for a wave to go through a complete cycle.7,21
Multiplexer, английский
- A device that combines a number of signals into one. often used in cctv to describe a device that is primarily used to multiplex several video signals into one for the purposes of recording or microwave transmission. it can also refer to a fibre optics mu
- Устройство, объединяющее несколько входных информационных потоков в один выходной. существуют следующие методы мультиплексирования: временное, статистическое, частотное
- Mux - мультиплексор
- This is a device that takes inputs from 2 or more video channels and combines them into one signal. this is often done by using time division multiplexing, which interleaves frames from each channel in such a way that they can be split out again. frequency division multiplexing uses different frequencies to achieve the separation of the signals.
- A device that combines two or more signals into a single output.
- Многоканальный коммутатор
- A device that funnels several different streams of data over a common communications line.
Demultiplexer, английский
- Демультиплексор, разуплот- йитель
- A device that separates a multiplexed signal into its original components; the inverse of a multiplexer.
- Демультиплексор; устройство разделения (каналов); устройство разуплотнения (каналов)

Cleave and crimp, английский
A connector installation technique, also known as a nopolish connector. the plug is installed onto the cable with the optic protruding from the end. the cable is crimped to the connector and the optic is cleaved as close to the connector endface as possible
Four wave mixing (fwm), английский
A collective name for a group of nonlinear processes where up to three different incident waves interact in the medium, resulting in a fourth wave
