Embedded World: Renesas builds Ethernet controller into RJ45 socket

Renesas is aiming at industrial controllers by building an entire Profinet interface inside an RJ45 connector. EtherCAT and EtherNet/IP versions will follow once associated software is ready. The hardware is accompanied by software to support the industrial Ethernet protocol stacks. Dubbed I-RJ45, there are single and dual port versions “which simplify integration for industrial Ethernet ...

Glasgow’s CST samples lasers for 10G optical networks

CST Global, the Glasgow semiconductor laser manufacturer, says it is sampling its 1270nm, 2.5Gbit/s asymmetric and 10Gbit/s symmetric, DFB lasers for 10G PON (passive optical network) applications. The firm is currently beta sampling its asymmetric 2.5Gbit/s lasers and alpha sampling its symmetric, 10Gbit/s lasers. The asymmetric beta samples, which are undergoing ITU-GR468 reliability testing, are ...
