![Time division multiplexing [TDM, left] uses very brief but broad-spectrum laser pulses to send data. Wavelength division multiplexing [WDM, center] packs in bits by using several frequencies of light at once. Orthognonal frequency division multiplexing [OFDM, right] does the same, but uses overlapping frequencies to make better use of the available spectrum.
