Abstract
A daisy-chain optical interconnection technique provides connectivity among a plurality of circuit boards. A plurality of optical cables is connected between pairs of the circuit boards to form a ring. Optical connection matrices disposed on each circuit board accept the ends of the optical cables. The optical connection matrices include optical vias to connect selected ones of the optical paths between ends of the optical cables. Unselected ones of the optical paths are coupled to optical transmitters and optical receivers on each board.
