Spectra7 and Foxconn to Demonstrate 400Gbps PAM4 Active Copper Cables
At lower speeds of 25Gbps, 40Gbps and 100Gbps these servers have been connected with passive direct attached copper (DAC) cables.
- 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.
- Spectra7's GaugeChangerTM chips allow smaller gauges down to 34AWG copper to be used thus dramatically improving both measurements.
