Over-40-Gb/s IC module technology using 8-mm-square leadless chip carrier packages mounted on four-layer resin printed circuit boards

A key technology for realizing small, low-cost IC modules for over-40-Gb/s optical communication systems has been developed. The technology mainly features 8-mm-square leadless chip carrier (LCC) packages and four-layer resin printed circuit boards (PCBs). It was applied to build a prototype multichip 1:4 DEMUX module operating at 45 Gb/s.
