This patent application discloses transmitting device for transmitting a plurality of spatial laser beams over a single fiberoptic glass monofilament, for conveying a plurality of signals without multiplexing. Means are provided for generating a plurality of laser beams, each of which are directed into the core of the fiberoptic monofilament of glass at a different angle to the longitudinal axis of the monofilament. Each of the beams also exit from the exiting end of the monofilament at different angles. Those inserted at an angle of the longitudinal axis exit in a conical annulus having the same angle as the angle in which the beam was originally inserted into the monofilament. Means are provided for intercepting each of said signals as they exit from the exiting end of the monofilament and converting them into electrical energy or extracting data therefrom.
