A compact 4 × 25 Gbps optical transceiver has been fabricated for an optical backplane system, which consists of a 4 × 25 Gbps DFB-LD array, a 4 × 25 Gbps PIN-PD array, and a CMOS transceiver chip. These are directly mounted on 9 × 14 mm(2) multi-layer ceramic package with an electromagnetic shield structure to suppress inner-channel crosstalk effectively.(More)
With the aim of prodi~ing a switch 121 with several-hundred-Gbh-class throughput, we first developed LAN-LSIs with 10-Cbh-class optical inpidoutput (I/O) buffer: The optical 110 buffer was supplied as a set consisting of an optical-electrical package, soft or hard macros of the optical interface, and library files for a targeted CMOS technology. Using such(More)
