ABSTRACT:
The invention concerns an apparatus and a system for the transfer of optical data between satellites, which encompasses a laser oscillator (10) for generating an optical signal, a modulator (11) for modulating the optical signal with data information, and an amplifier assemblage, a collimator assemblage, and a transmission device for transfer of the signals.Provision is made for a preamplifier (12) to be connected to a power divider section (13) downstream from which is a parallel circuit of at least two phase shifters (14) and main amplifiers (15), respectively connected in series, for amplification and adjustment of the optical signals; and for the main amplifiers (15) to be connected, via a bundle (16) of optical waveguides corresponding to the number of series circuit(s), to the corresponding number of collimators (17).
