PROBLEM TO BE SOLVED: To provide a system that decides alignment data in optical communication connection between a receiver and a transmitter placed apart from the receiver. SOLUTION: In the system that decides alignment data for optical communication connection between a receiver and a transmitter, at least one of the following processes, that is, a process in which an output spontaneously emitted from an optical pre-amplifier in the receiver is used as an output signal for alignment of an optical telescope of the transmitter, or a process in which an output spontaneously emitted from an optical output amplifier of the transmitter is used by the receiver for the alignment of the reception telescope, is executed. This receiver is provided with a filter 11 to separate a data signal 8 from a spontaneously emitted output 9 and with a means 12 that processes the spontaneously emitted output as an output signal for alignment of a telescope 10. |
