Small-sized 10-gbit/s Optical Transmitter And Receiver Modules Including 8-bit Mux/demux Ics

Abstract

High-speed optical data transmitter and receiver modules have been developed. These modules are core parts of the high-speed optical bus link, which will support an environment of highperformance computer networking. These modules have been made an extremely smallsize of 63 x 14.7 x 12 mm and can not only transmit or receive optical 10-Gbit/s signals but also make 8-bit parallel-toserial data conversion, or vice versa. GaAs MESFET ICs of 0.5-pm gates were used in the modules for their ability of over 10-Gbit/s operating and a good yield of them. The structure of packages and substrates are contrived to suppress all unintentional resonances up to around 10 GHz. High-speed signal transmitting and receiving tests for individual modules have shown successful operation at 10 Gbits/s.
