RHiNET-2/SW: a high-throughput, compact network-switch using 8.8-Gbit/s optical interconnection

We have developed a high-throughput, compact network switch (the RHiNET-2/S W) for a distributed parallel computing system. Eight pairs of 800-Mbit/s x 12-channel optical interconnection modules and a CMOS ASIC switch are inte grated on a compact circuit board. To realize high-throughput (64 Gbit/s) a nd low-latency network, the SW-LSI has a customized high-speed LVDS I/O int erface, and a high-speed internal SRAM memory in a 784-pin EGA one-chip pac kage. We have also developed device implementation technologies to overcome the electrical problems (loss and crosstalk) caused by such high integrati on. The RHiNET-2/SW system enables high-performance parallel processing in a distributed computing environment.
