A two-layer parallel optical interconnection network has been designed. The top layer was a star network,which was made up of digital routing nod,node computer and optical network interface cards. The maximum transmission rate of single channel was 1.4 Gbit/s and the total throughput of network was more than 10 Gbit/s with eight channels. The bottom layer was a ring comprising optical network interface cards and node computer. The peak transmission rate of optical interface cards was 1.065 Gbit/s. Fiber optic rotary joints that can transmit dynamic data were assembled in sub-layer network between the node computer and sensors. The maximum communication latency inside a ring was less than 5.292 μs. The average communication latency of parallel optical interconnection network was 11.03 μs,and the bandwidth of the ring network was less than 50 Mbit/s.
