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. [ 1] The selection is directed by a separate set ...
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.
Multiplexing. Time-division multiplexing ( TDM) is a method of transmitting and receiving independent signals over a common signal path by means of synchronized switches at each end of the transmission line so that each signal appears on the line only a fraction of time according to agreed rules, e.g. with each transmitter working in turn. It ...
e. In telecommunications, frequency-division multiplexing ( FDM) is a technique by which the total bandwidth available in a communication medium is divided into a series of non-overlapping frequency bands, each of which is used to carry a separate signal. This allows a single transmission medium such as a microwave radio link, cable or optical ...
Conceptually, OFDM is a specialized frequency-division multiplexing (FDM) method, with the additional constraint that all subcarrier signals within a communication channel are orthogonal to one another. In OFDM, the subcarrier frequencies are chosen so that the subcarriers are orthogonal to each other, meaning that crosstalk between the sub ...
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.
If a signal is connected to different outputs (changeover switches, multiplexers), multiple transmission gates can be used as a transmission gate to either conduct or block (simple switch). A typical example in 4000-series and 74-series called the 4066 4-way "bilateral switch" can handle analog or digital signals and is available from various ...
An add-drop multiplexer ( ADM) is an important element of an optical fiber network. A multiplexer combines, or multiplexes, several lower- bandwidth streams of data into a single beam of light. An add-drop multiplexer also has the capability to add one or more lower-bandwidth signals to an existing high-bandwidth data stream, and at the same ...
