Spectra7 Microsystems Inc., a leading provider of high-performance analog semiconductor products for broadband connectivity markets, announced that it will partner with Volex plc (Volex) to demonstrate Spectra7’s new 112G PAM4 GaugeChanger chip intended for next generation 800Gbps data center interconnects at this year’s annual DesignCon Conference and Exhibition being held in Santa Clara, CA from February 1-2, 2023. The demonstration will highlight a Volex 3-meter 28AWG Active Copper Cable with Spectra7’s GC1122 ICs.
“New network architectures and increased server speeds are causing the connectivity market inside the data center to embrace active solutions,” said Alan Weckel, Founder and Technology Analyst with 650 Group. “By 2026, we expect over 70% of the Cloud server market to be active copper. From a revenue perspective, the market will quickly exceed US$1B and can exceed US$3B by 2026, far higher than the DAC market it will replace. Active copper cables also help support the US$20B, and growing, Ethernet market in the data center which is critical for the future growth of Cloud and AI/ML applications.”

“We are proud to have Volex as a partner for 800G interconnects using our GaugeChanger™ ICs,” said Spectra7 CEO Raouf Halim. “We see strong demand from customers for the low power cost effective 800G cables that we are jointly bringing to the hyperscale data center market.”
The GC1122 is the latest addition to the GaugeChanger™ product line and extends the data rate from 56 to 112Gbps per lane. Since the GC1122 is analog and highly linear, dynamics such as line rate adjustment, multi-level signaling, intermittent line silence, transmit pre-emphasis or amplitude adjustment and receiver adaptivity are fully preserved. GC1122 chips are now sampling to leading cable partners and end customers.
Spectra7’s GaugeChanger™ is an innovative technology that allows copper to extend much longer lengths without the cost and power penalty of optics or DSP based retimed copper solutions. It works equally well at 25G NRZ, 56G PAM4 and 112G PAM4 signaling, enabling Ethernet interface standards of 100, 200, 400, 800Gbps and 1.6Tbps.
