Spectra7 Microsystems Inc. announced that Tencent demonstrated 200Gbps and 400Gbps Active Copper Cables (ACCs) enabled by Spectra7’s technology at China’s Open Data Center Committee (ODCC) conference held in September in Beijing. Tencent recently completed qualification of these 200Gbps Spectra7 enabled cables and has now begun an initial trial run network deployment. Tencent is already using Spectra7 enabled ACC cables in its data centers for 25Gbps server interconnect. The 200Gbps demonstration showed a Spectra7 enabled ACC “splitter cable” connecting from a 200Gbps top-of-rack (ToR) switch port to 2 separate servers with 100Gbps ports. The signaling in the cable was 50Gbps PAM4. This architecture is being widely planned in China for next generation deployments. Tencent also demonstrated a 400Gbps QSFP-DD PAM4 Spectra7 based ACC for future applications. GaugeChanger™ is an innovative and disruptive technology that allows copper to extend much longer lengths without the cost and power penalty of optics. It works equally well at 25 Gbps NRZ and 50 Gbps PAM4 enabling new connector standards of 100, 200 and 400 Gbps.
