Multiplexing

The combining of two or more information channels onto a common transmission medium is called multiplexing. In electronical communications, the two basic forms of multiplexing are time-division multiplexing (TDM) and frequency-division multiplexing (FDM).

In optical communications, the analog of FDM is wavelength-division multiplexing WDM.

A simple form of multiplexing is to use a lot of wires in one cable. This is called space division multiplex.

The application shows graphics for all three multiplexing types
