Abstract
A device configure to wirelessly transmitting optical signals via a satellite communication link includes a first sending arrangement and a first receiving arrangement. The first sending arrangement is configured to transmit optical signals via a first transmission path and a second transmission path to the first receiving arrangement. The first transmission path has a first transmission channel and the second transmission path has a second transmission channel. In addition, the first transmission channel 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.

A device configured to wirelessly transmit optical signals via a satellite communication link, the device comprising:
- a first sending arrangement;
- and
- a first receiving arrangement;
- wherein the first sending arrangement is configured to transmit optical signals via a first transmission path and a second transmission path to the first receiving arrangement,
- wherein the first transmission path has a first transmission channel and the second transmission path has a second transmission channel,
- wherein the first transmission channel is physically separated from the second transmission channel,
- wherein the second transmission channel is a low-rate transmission channel for transmitting amplitude-modulated optical signals,
- wherein a bandwidth of the second transmission channel is lower than a bandwidth of the first transmission channel, and
- wherein the second transmission channel is a control channel between terminals which are not compatible with one another via the first transmission channel such that at least one of confirmation packets and configuration packets are transmitted via the second transmission channel.
A satellite communication link, comprising:
- a device configured to wirelessly transmit optical signals via a satellite communication link, wherein the device includes a first sending arrangement and a first receiving arrangement,
