Abstract
Abstract An optically connectable circuit board and optical components mounted thereon. At least one component includes optical transceivers and provides an optical connection to the board. Electronic components may be directly connected to the board electrically or optically. Also, some electronic components may be indirectly connected optically to the board through intermediate optical components.
