Schematic of a 1-to-2 demultiplexer. Like a multiplexer, it can be equated to a controlled switch. In electronics, a multiplexer (or mux; spelled sometimes as multiplexor), also known as a data selector, is a device that selects between several analog or digital input signals and forwards the selected input to a single output line.

A DWDM terminal demultiplexer. At the remote site, the terminal de-multiplexer consisting of an optical de-multiplexer and one or more wavelength-converting transponders separates the multi-wavelength optical signal back into individual data signals and outputs them on separate fibers for client-layer systems (such as SONET/SDH).
Multiplexing. Multiple low data rate signals are multiplexed over a single high-data-rate link, then demultiplexed at the other end. In telecommunications and computer networking, multiplexing (sometimes contracted to muxing) is a method by which multiple analog or digital signals are combined into one signal over a shared medium.
An optical add-drop multiplexer ( OADM) is a device used in wavelength-division multiplexing (WDM) systems for multiplexing and routing different channels of light into or out of a single-mode fiber (SMF). This is a type of optical node, which is generally used for the formation and the construction of optical telecommunications networks.
The orange lines only illustrate the light path. The light path from (1) to (5) is a demultiplexer, from (5) to (1) a multiplexer. Conventional silica-based AWGs, as illustrated in the figure above, are planar lightwave circuits fabricated by depositing layers of doped and undoped silica on a silicon substrate.
Learning styles. Learning styles refer to a range of theories that aim to account for differences in individuals' learning. [ 1] Although there is ample evidence that individuals express personal preferences on how they prefer to receive information, [ 2]: 108 few studies have found validity in using learning styles in education. [ 3]: 267 Many ...
A three-port to one-port multiplexer is known as a triplexer, and a four-port to one-port multiplexer is a quadplexer or quadruplexer. A typical diplexer may have around 30 dB isolation between its L and H ports. That isolation is sufficient for many applications, but it is insufficient to allow simultaneous reception and transmission on one ...
A high data rate signal is inverse multiplexed over multiple slower links, then recombined. An inverse multiplexer (often abbreviated to inverse MUX or IMUX) allows a data stream to be broken into multiple lower data rate communication links. An inverse multiplexer differs from a demultiplexer because the multiple output streams from the former ...
