The apparatus includes several optical waveguides which form passive node points at their connection points. These node points provide for the splitting up of the data transmitted as light, into the combined optical waveguides. The node points each have coupling surfaces (5) in the input region of an associated waveguide (2). These surfaces lead to a maximum precisely defined reflection of the light and thus lead to transmission of maximum optical power to a next node point. The coupling surfaces also provide for separating a defined minimum optical power for the optical waveguide of the individual node points. At the coupling surface (5), there may be provided a coupling body with a smooth surface and a prism structure. An optical coupling body with an opto-coupler may be provided at the coupling surface. The coupling bodies may be made of polycarbonate. The coupling bodies may have associated lens systems. |
