Abstract: An apparatus comprises an optical data receiver to receive first and second data-modulated optical carriers in different wavelength bands via a free space optical link and to generate an output digital data stream from demodulated segments of the first and second data-modulated optical carriers. The optical data receiver is configured to make selections between temporally corresponding portions of the first and second data-modulated optical carriers for generating successive portions of the output digital data stream. The optical data receiver is configured to make one of the selections between two of the temporally corresponding portions of the first and second data-modulated optical carriers based on at least one value of a quality indicator obtained for at least one of two temporally corresponding portions.
