Patent ID: 8428459

Claim:
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 a 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 the 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; and a plurality of optical slots connected to the respective optical transmission means to connect the external devices so that the optical signal is input/output.
