Abstract

Transmitting at least two optical signals to at least two receivers, using a source, an alignment module, and a telescope. The telescope has a field of view in which the at least two receivers are located, and at least a first beam path and a second beam path are aligned in the alignment module in order to respectively steer the first optical signal via the telescope to the first receiver and the second optical signal via the telescope to the second receiver.
