We report on the demonstration of a bidirectional free-space link over 18 km as part of the
European-Union project “VERTIGO” that investigates technologies for the optical GEO …

A 1 Tbit/s 53km single channel free-space optical (FSO) link is demonstrated. High
bandwidth, high order modulation formats and advanced adaptive optics are utilized. We …

A 2.5 Gb/s optical link at 1550 nm over a distance of 1.1 km has been demonstrated
between two identical terminals by using standard commercial optoelectronic devices …

Free-space optical (FSO) communication based on laser technology is a promising
opportunity for the nextgeneration ultra-high data rate links from satellites to ground and vice …

A 5.6 Gbps optical communication link has been verified in-orbit. The intersatellite link uses
homodyne BPSK (binary phase shift keying) and allows to transmit data with a duplex data …

Today, coherent optical inter-satellite links are operational in LEO-LEO constellations for
more than two years. With data transmitted error free at rate of 5.625 Gbps and links …

Current satellite communication systems based on RF technology are often limited by the
available spectrum. Free-Space Optical Communication Links are a promising solution to …

A 2.1 km terrestrial free-space optical data link operating at 5 Gbps by using WDM and 1550
nm fiber communication techniques was established. Two 2.5 Gbps pattern generators are …

Free-space optical (FSO) communication technologies constitute a solution to cope with the
bandwidth demand of future satellite-ground networks. They may overcome the RF …

We report on a demonstration of a bidirectional, multi-aperture free-space optics (FSO)
system and discuss general system design aspects. A multi-aperture terminal is used for …
