A platform for video data link between FPGA microprocessors based on an optical printed-circuit board (OPCB) was implemented. Optimized compact size of 9.5 x 10.5 x 1.0 mm3 Tx/Rx modules were prepared and applied for the optical link of the platform. A low insertion loss of 0.42 dB and stable optical fiber-layer integrated with connectors was embedded in FR4 board for the implementation of the OPCB. The platform shows that embedding the optical fiber-layer with connectors can improve the degree of freedom for packaging as well as optical and physical characteristics. Real time video image from a charge-coupled-device (CCD) camera was successfully transmitted to a monitor through optical link between FPGA microprocessors of the platform. The captured image was successfully saved in a static random access memory (SRAM) and clearly shown on the monitor. This study shows that chip-to-chip optical interconnection technology based on fiber-layer embedded OPCB can be applied for the CPU-to-CPU/memory optical interconnections.
