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.
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). Originally ...
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 ...
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.
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 ...
Statistical multiplexing is used to allow several video, audio and data streams of different data rates to be transmitted over a bandwidth-limited channel (see Statistical multiplexer ). The packets have constant lengths. The channel number is denoted Program ID (PID). The UDP and TCP protocols, where data streams from several application ...
STS multiplexer and demultiplexer. STS multiplexer and demultiplexer provide the interface between an electrical tributary network and the optical network. Add-drop multiplexer. Add-drop multiplexers (ADMs) are the most common type of network elements. Traditional ADMs were designed to support one of the network architectures, though new ...
