PROBLEM TO BE SOLVED: To provide a device for wirelessly transmitting optical signals via a satellite communication link.SOLUTION: There is provided a device (10) for wirelessly transmitting optical signals via a satellite communication link (1). The device includes a first sending arrangement (110, 210) and a first receiving arrangement (120, 220). The first sending arrangement (110, 210) is configured to transmit optical signals via a first transmission path (100) and a second transmission path (200) to the first receiving arrangement. The first transmission path (100) has a first transmission channel (130A) and the second transmission path (200) has a second transmission channel (130B). Here the first transmission channel (130A) is physically separated from the second transmission channel, while the second transmission channel is a low-rate transmission channel for transmitting amplitude-modulated optical signals.SELECTED DRAWING: Figure 2 |
