As next generation data center interconnects transition to 112Gbps PAM4 per lane to meet higher bandwidth and throughput demands, passive copper cables can only enable reaches of up to 1.5 meters. This severely limits the use cases of passive copper cables in data centers at 112Gbps and has created a strong demand for active copper cables (ACCs) that extend the copper cable reaches to allow for the high-volume switch-to-server connections. The CopperEdge GN8112 is a 112Gbps PAM4 quad channel linear equalizer designed to enable low cost, manufacturable ACCs that can deliver reaches of up to five meters over a copper twinaxial (Twinax) cable assembly. This reach extension enables ACCs to service the large volume 400G and 800G data center interconnects while offering ultra-low power (
