An 80 Gbit/s ATM-switch multi-chip module (MCM) has been developed that use
s only an optical I/O interface for high-speed signal interconnection. The
MCM was fabricated using 0.25 mu m CMOS/SIMOX technology, 622 Mbit/s/channe
l 40 channel/module parallel-optical-interconnection technology, and highpe
rformance cooling technology. Its small size (220 x 174 x 15mm) will enable
80 Gbit/s optical ATM cell switching.
