Large-throughput parallel optical interconnection for a distributed parallel computing system

We produced a large-throughput optical interconnection for a distributed parallel computing system. It transmits optical data at a rate of over 800-Mbit/s/spl times/10-bit through a 50-m single-mode fiber, using a CMOS MUX/DEMUX and retiming circuits. We measured the BER to be less than 10/sup -9/.
