  • a plurality of optical transmitting and receiving devices that radiate an outgoing optical signal to a space, or receive an incoming optical signal from the space;

    arrangement mechanics on which is mounted said plurality of optical transmitting and receiving devices at different positions;

    an optical system that transmits, when the optical signal is radiated from said optical transmitting and receiving devices, the optical signal to the space by refracting the optical signal to form spherical waves, and focuses, when the optical signal arrives from the space, the optical signal onto said optical transmitting and receiving devices; and

    a selector that selects a desired optical fiber from a plurality of optical fibers mounted on said arrangement mechanism, and that connects the optical fiber selected to said optical transmitting and receiving devices.
