Some Multiplexer Types Introduction

 

 

Telephone networks first used multiplexing to transmit conversations over twisted pairs of wires. Multiplexing allows people the ability to receive large amounts of information through one line on computer and telecommunications networks. It works with a multiplexer, an apparatus that compresses data. Analog or digital data streams combine on one signal through a shared medium. There are various types of multiplexing that helps transfer data.

 

Frequency Division Multiplexing (FDM)

 

Frequency division multiplexing or FDM initially worked with early telephone systems. It splits the various frequencies to maintain numerous users. For example, a multiplexer can divide the frequency to support 6 users or more on a standard sound spectrum with 20 Hz to 20,000 Hz. This type of multiplexer commonly supports FM radio, cable television, and older model analog mobile networks.

Time Division Multiplexing (TDM)

 

The time division multiplexing was released with digital technology in the late 1950s. With a time division multiplex, more data can pass through one particular network, and it converts analog signals to digital signals. A type of time division multiplexing is the synchronous TDM that people opt for with ISDN. Another type of TDM is a statistical TDM, when the multiplexer uses times slots based on a particular channel's needs.

 

Dense Wavelength Division Multiplexing (DWDM)

 

A dense wavelength division multiplexing system is a variation of a FDM or TDM. This type of multiplexing system operates similar to a FDM by dividing the frequency across the channels. However, DWDM also operates with different colored lasers that transmit each segment of frequencies. Some people may refer to this type of multiplexing as a wave division multiplexing.

 

Code Division Multiplexing

 

Code division multiplexing is a method of transmitting each channel that has pulses of codes. Additionally, each channel has a different code and relays over a fiber or asynchronously through a multiplexer. Global positioning system use code division multiplexing.
