ABSTRACT:
The invention provides a printed circuit board having an optical data buss incorporated therein. Optical fibers are imbedded within the body of the printed circuit board and form an optical data circuitry within the board. Holes are formed in the printed circuit board at predetermined locations to receive a novel chip carrier. The chip carriers have a transparent area that interfaces with the optical fibers. Optical data entering the chip carrier is intercepted by an optical beam-splitter where the signals are directed to a photo transistor die for conversion to electrical signals which are then conducted to an integrated circuit die and into the printed circuitry of the printed circuit board. Electrical data signals from the printed circuit board may be conducted to the chip carrier which also contains a photo-transmitter die where the electrical data signals are converted to optical signal data and are projected to a beam-splitter for deflection into the optical fiber circuitry. When arranged in a stack, printed circuit boards are separated by physically contacting heat conductive plates which may be aluminum that act as heat sinks for cooling purposes. Holes drilled through the plates allow optical data signals to be projected from any one printed circuit board to another throughout the stack. A novel connector is provided to supply electrical power, electrical data input, and optical data input to the system. The optical circuitry is bidirectional.
