On-board optical interconnection of 2.5Gb/s x 12 channels data using fiber-embedded PCB

A simple method for fabricating fiber-embedded boards using a grooving technique for optical interconnects is described. It is quite cost effective and fully compatible with conventional PCB processes. On-board optical link of 2.5Gb/s signals between the transmitter and the receiver modules was demonstrated by placing connecting blocks having 45°-mirror planes at the ends of the fiber-embedded boards.
