400Gbps interconnects are increasingly being used to interconnect high-powered Artificial Intelligence (AI) and Machine Learning (ML) servers that need this massive bandwidth to analyze increasingly large and complex data sets as well as to serve the rising focus on parallel computing in these data centers. At lower speeds of 25Gbps, 40Gbps and 100Gbps these servers have been connected with passive direct attached copper (DAC) cables. Now at 400Gbps, Hyperscalers are requiring thinner and more flexible cables to accommodate the increased rack density. Bringing a 400Gbps passive DAC to each server is challenging, as these cables are usually 26AWG and extremely difficult to route. Bend radius and bend space are key cable parameters. Spectra7’s GaugeChanger^TM chips allow smaller gauges down to 34AWG copper to be used thus dramatically improving both measurements. Foxconn will be demonstrating a 2.5-meter 34AWG ACC to address this application.

Hyperscalers are also requiring longer cables to accommodate increased switch radix. At 400Gbps, passive DACs can only reach about 2.5 meters. Foxconn will be demonstrating a 5 meter 28AWG ACC to address these longer reach applications.

“Foxconn is a technology and market leader,” said Spectra7 CEO Raouf Halim. “We are proud to be partnering with them in the burgeoning Active Copper Cable market and delighted to be showcasing our technology with them at the DesignCon 2021 expo.”
