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.
Claims6
An optically connectable circuit board comprising:
- a printed circuit card with a plurality of component attach locations and a plurality of optical channels, at least one surface including ones of said plurality of optical channels;
- a plurality of electronic components mounted in said component attach locations;
- at least two electronic components of said plurality of electronic components including a plurality of optical transceivers, a first electronic component of said at least two electronic components being an optical connection to said printed circuit card;
- and
- a second electronic component of said at least two electronic component comprises:
- an optical interposer including at least one chip attach location on a first surface and attached to one said component attach location, at least one integrated circuit chip mounted on said chip attach location, and
- optical transceivers electrically connected to said integrated circuit chip and optically connected to corresponding said optical channels;
- wherein said optical transceivers optically connect said second electronic component with said plurality of optical transceivers included with said first electronic component through said plurality of optical channels;
- and
- wherein one or more of said plurality of component attach locations are on said at least one surface.
