Free Space Optics (FSO) is a telecommunication technology that uses light propagating in free space to transmit data between two points. The optical links usually use infrared laser light, although low-data-rate communication over short distances is possible using LEDs. IrDA is a very simple form of free-space optical communications.

FSO systems can function over distances of several kilometers. As long as there is a clear line of sight between the source and the destination, communication is theoretically possible. Even if there is no direct line of sight, strategically positioned mirrors can be used to reflect the energy. The beams can pass through clean glass windows with little or no attenuation.

Sintelsat Free Space Optics (FSO) Solution is aimed to provide link availabilities up to 99.999% over rated ranges 50 m up to 5000 m. Cost effective solutions can be designed for the deployment of Metropolitan Data Networks and Cellular/PCS Backhaul links.

• Uses 1550 nm wavelength laser technology, Eye Safe even directly in front of the laser transmitter window


• Engineered to higher laser power performance that allows to operate over longer distances, penetrate denser fog for higher availability, support higher data rates- or any combination of these benefits


• Critical subsystems were extensively designed and manufactured to ensure high reliability even when used in laser communications systems for military and space applications


• Significant advances in FSO technology into the transmitter and receiver subsystems enable to deliver improved performance relative to competing systems

Free space optical (FSO) systems offers a flexible networking solution that delivers on the promise of broadband. Only free space optics or Free Space Optics (FSO) provides the essential combination of qualities required to bring the traffic to the optical fiber backbone – virtually unlimited bandwidth, low cost, ease and speed of deployment. Freedom from licensing and regulation translates into ease, speed and low cost of deployment.

Since Free Space Optics (FSO) optical wireless transceivers can transmit and receive through windows, it is possible to mount Free Space Optics (FSO) systems inside buildings, reducing the need to compete for roof space, simplifying wiring and cabling, and permitting the equipment to operate in a very favorable environment. The only essential for Free Space Optics (FSO) is line of sight between the two ends of the link.
