The instant invention relates to a method and an arrangement for optical information transmission via satellites by means of broadband optical modulation and reception technology. As a rule, the arrangement is realized in optical satellite terminals, which have optical units, a laser unit, control and supply as well asmonitoring units. In the exemplary embodiment, these terminals are designed for a data rate of 1.5 Gbit/s and a transmission distance of more than 1,200 km, whilehaving a weight of less than 8 kg.

La présente invention porte sur une méthode et une installation de transmission optique d'informations par satellites au moyen d'une technologie de modulation et de réception optique à large bande. En général, l'installation de l'invention est réalisée dans les terminaux de communication optique par satellites, lesquels comportent des unités optiques, une unité laser et des unités de commande, d'alimentation et de surveillance. Dans la concrétisation servant d'illustration, ces terminaux ont un débit de données de 1,5 Gbit/s et un poids inférieur à 8 kg, alors que la distance de transmission dépasse 1 200 km.
