Hi Remo,
As FSO is line-of-sight technology approach uses invisible beams of light to provide optical bandwidth connections. It’s capable of sending up to 1.25 Gbps of data, voice, and video communications simultaneously through the air — enabling fiber-optic connectivity without requiring physical fiber-optic cable. It enables optical communications at the speed of light.
Originally developed by the military and NASA, FSO has been used for more than three decades in various forms to provide fast communication links in remote locations.
FSO technology is surprisingly simple. It’s based on connectivity between FSO-based optical wireless units, each consisting of an optical transceiver with a transmitter and a receiver to provide full-duplex (bi-directional) 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.
At this point, the receiving lens or telescope connects to a high-sensitivity receiver via optical fiber.
Thanks,
