Experimental demonstration of 10?Gbit?s transmission with an optical backplane system using optical slots

A practical optical backplane system was prepared with transmitter–receiver processing boards and an optical backplane made from polymeric-waveguide-embedded optical printed-circuit boards. Optical slots were used as connection components between the transmitter–receiver processing boards and the backplane board to permit easy and repeatable insertion and extraction of the boards with micrometer precision. We report $10\mathrm{Gbit}∕\mathrm{s}$ data transmission between an optical backplane and the transmitter–receiver processing boards.
