Preserve 800G throughput across extended rack and row connections with this QSFP-DD to QSFP-DD active electrical cable. The 7 m reach gives infrastructure teams more placement flexibility than short passive DACs, while keeping the link in a direct copper path for low-latency interconnects. Designed for 800GBASE-CR8 deployments, this cable fits high-density switching environments where port count, cable management, and signal integrity all matter. Active electrical construction helps maintain link quality over longer distances, making it a practical choice for top-of-rack to end-of-row designs, switch interconnects, and tightly packed data center fabrics. Arista compatibility simplifies qualification in environments built around that platform, reducing deployment friction for teams standardizing on specific switch families. For buyers comparing lower-cost passive options, this model earns its place when the run length, port density, and operational margin demand more than a basic twinax assembly can provide.
