A tour of the show floor at DesignCon revealed boards, testers, and other enabling technologies for high-speed systems hitting 100G rates.
Texas Instruments and TE Connectivity collaborated on a demo of a backplane carrying 100 Gbit/s Ethernet signals based on the emerging IEEE 802.3bj standard. TI supplied the re-timer chips, and TE provided connectors for the 4x25G demo (above) that carried signals for a meter in the face of 35 dB loss conditions.
They also showed two other working 100 Gbit/s system demonstrations: an orthogonal midplane and a two-meter backplane cable assembly. The orthogonal midplane eliminates the backplane to reduce insertion loss, providing needed margin to send next-generation 40 Gbit/s and 56 Gbit/s signals between two boards.
