Free-space optical transceiver, illustration. Free-space optical communication (FSO) is a communications technology that uses light beams to transmit data wirelessly through air, a vacuum, or space. The optical part of the device is the receiver optics (centre left). The input beams (blue) are focused by the optics onto the detector (centre right), which then passes the signal to the data processor (far right). Outgoing data is passed from the processor to a laser transmitter (centre), which sends the data as output beams (pink) via the transmitter optics (centre left). This technology in its ultra-long-range form can be used by spacecraft, but long range applications on Earth are hindered by the effects of weather.
