400G QSFP-DD DAC

High-speed cabling solutions for 800G data centers, including DAC, AOC, and fiber optics, are essential for efficient, reliable, and seamless data transmission in modern data centers.

While optical cables dominate many data center applications, copper cables, such as DAC, remain widely used due to their cost-effectiveness and reliability. However, DAC cables have distance limitations, which can be mitigated by combining them with ACC. This approach significantly reduces the connection costs for high-speed data centers.

DAC cables are becoming crucial in AI clusters. See how copper interconnects save costs and improve efficiency over traditional multimode optical modules. NADDOD's cost analysis of HGX H100 AI clusters shows that combining DAC with single-mode optical modules offers significant savings.
