Free Space Optics (FSO) is an optical communication technology that uses light propagating in free space to wirelessly transmit data for telecommunications or computer networking. Originally developed by the military and NASA, Free Space Optics has been used for nearly thirty years.
This surprisingly simple technology is based on connectivity between Free Space Optic-based optical wireless units, consisting of an optical transceiver with a transmitter and a receiver to provide full-duplex capability. Each optical wireless unit uses an optical source, plus a lens or telescope that transmits light through the atmosphere to another lens receiving the information.
FSO (Free Space Optics) is capable of sending up to 1.25 Gbps of data, voice and video. Free Space Optics is like fiber-optic connectivity without using physical fiber-optic cable. It enables optical communications at the speed of light, achieving the fastest data transmission possible.
