ABSTRACT:
Optical signals are coupled between circuit cards, electrically connected to a backpanel, by means of parallel elongate optical conductors formed by an optically conductive plastics moulding mounted on the backpanel. Each elongate optical conductor ends in an inclined face to direct an optical signal between the optical conductor and an optical signal source or detector on a respective circuit card.
