1. A system for the optical transmission of signals, comprising:

  • a first and a second light guide with internally reflecting boundaries respectively connected to a transmitter and a receiver of luminous signals, said light guides having proximal ends respectively emitting and collecting bundles of light rays with axes angularly intersecting in a common plane, each bundle being bounded by a pair of limiting rays on opposite sides of the respective axis; and

    a mirror confronting said proximal ends for reflecting light rays from said first light guide to said second light guide, said mirror having a cross-section in said common plane in the shape of a segment of an ellipse whose foci are the center points of said proximal ends within said common plane, said segment extending between the intersection of the axis of said first light guide with the position of a limiting ray of said second light guide and the intersection of the axis of said second light guide with the position of a limiting ray of said first light guide.
