ABSTRACT:
An optical coupler includes a transparent sphere having a reflective coating on the surface thereof for reflecting light within the sphere. A light source optical transmission line introduces light into the sphere which radiates directly to output optical transmission lines. The light introduced into the sphere is also reflected one or more times and is then introduced into one of the transmission lines.
