Optical I/O bus system

An optical input/output (I/O) bus system for connecting a plurality of external devices with a central processing unit (CPU) or memory in a specific system using an optical signal, comprising:

• an array module including an laser diode (LD) array configured to convert an electrical signal output from the CPU or memory into an optical signal, a photonic diode (PD) array configured to convert an optical signal output from the external devices into an electrical signal, a transceiver array configured to transceive the electrical signals, and a controller configured to control the PD array, the LD array, and the transceiver array to connect the CPU or memory with a corresponding external device using the optical signal according to an address of an input signal;
• a plurality of optical transmission means disposed in parallel to transfer the optical signal converted by the array module;
• a plurality of photoelectric converters connected to the array module through the respective optical transmission means, and configured to convert an electrical signal into an optical signal or an optical signal into an electrical signal;
• a plurality of serializer and deserializers (SerDeses) connected with the respective photoelectric converters, and configured to divide a serial electrical signal into parallel electrical signals or combine parallel electrical signals into a serial electrical signal;
• and
• a plurality of electrical slots connected to the respective SerDeses to connect the external devices so that the serial/parallel electrical signals are input/output.
