Analog signals, for example, are combined using frequency-division multiplexing (FDM), in which the bandwidth is divided into parallel channels of different frequencies. Digital signals can be transmitted using time-division multiplexing (TDM), in which signals are carried using alternating time slots. On Fiber Optic networks, multiple signals are transmitted as light split into different wavelengths, a process known as wavelength-division multiplexing (WDM).
