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.
Claims9
An optically connectable circuit board comprising:
- a printed circuit card with a plurality of chip attach locations;
- a plurality of optical channels in a surface layer of said printed circuit card;
- an electronic component mounted in each of said chip attach locations and grouped into local area groups;
- a plurality of optical components including at least one onboard transceiver, the at least one said onboard transceiver comprising a plurality of optical transceivers, each of said plurality of optical transceivers optically connected to a corresponding optical channel, each of said local area groups being indirectly optically connected to said printed circuit board through an electrically connected one of said plurality of onboard transceivers;
- and
- at least one of said plurality of optical components includes an off board transceiver having a plurality of said optical transceivers, each having an optical connection to one of said plurality of optical channels.
