Difference Between Multiplexer and Demultiplexer

Introduction

Multiplexing and demultiplexing are two terms used often in the realm of network transmission. Whether or whether you have any questions regarding your network connection, it is always a good idea to have a broad awareness of it in case of emergency. This article will explain what they are and how they vary from multiplexing and demultiplexing.

What is the definition of Multiplexing?

Multiplexing (Muxing) is a word used in computer networking and communications. It refers to the method and practise of sending several analogue or digital input signals or data streams via a single channel. The high-speed channel is successfully exploited because many low-speed channels may be combined into one high-speed channel for transmission. Communication carriers may avoid maintaining several lines by employing multiplexing, resulting in significant cost savings.

A multiplexer (Mux) is a device that accomplishes the process of multiplexing. It's a piece of gear that combines many analogue or digital input signals into a single transmission line.

What is the definition of Demultiplexing?

Multiplexing is referred to as demultiplexing (Demuxing). The procedure is the inverse of multiplexing. Demultiplexing is the process of turning a signal with multiple analogue or digital signal streams back to their original, unconnected signals.

Demultiplexing is the inverse of multiplexing, however it is not the polar opposite of multiplexing. Inverse multiplexing (iMuxing) is the polar opposite of multiplexing, in which one data stream is split into numerous related data streams. The distinction between demultiplexing and inverse multiplexing is that demultiplexing's output streams are unrelated, but inverse multiplexing's output streams are linked.

A demultiplexer (Demux) is a device that reverses the multiplexing process.

Comparison Table Between Multiplexing and Demultiplexing

Multiplexing Demultiplexing
  • Multiplexers combine digital data from several sources into a single source.
  • A demultiplexer takes digital data from a single source and splits it into multiple sources.
  • It's called Data Selector.
  • It's called a Data Distributor.
  • A digital switch is a multiplexer.
  • A digital circuit is a demultiplexer.
  • It is based on combinational logic.
  • It also adheres to the logic of combination.
  • It accepts n data inputs.
  • There is just one data entry.
  • It just has one data output.
  • There are n data outputs.
  • It operates on the premise of many to one.
  • It operates on the one-to-many concept.

Conclusion

Multiplexing and demultiplexing are two common CWDM and DWDM technologies. A multiplexer (Mux) is used to multiplex signals, while a demultiplexer is used to demultiplex signals (Demux). Nowadays, a typical device will be capable of both multiplexing and demultiplexing. FS's CWDM Mux Demux and DWDM Mux Demux are two examples.
