Build 800G interconnects with the reach needed for tightly packed infrastructure using a 2 m QSFP-DD to QSFP-DD active copper cable. This 800GBASE-CR8 twinax assembly is designed for short-reach, high-bandwidth links between switches, servers, and adjacent network nodes. The active copper design helps maintain signal integrity across the cable run, making it a practical choice when equipment is not mounted side by side but still sits within a compact rack or neighboring cabinet. Arista compatibility supports environments standardized on QSFP-DD 800G ports, reducing friction during deployment and procurement. At 2 m, this cable gives teams more placement flexibility than a 1 m assembly while staying within the direct-attach copper category. That makes it well suited for leaf-spine fabrics, lab validation, and dense production rows where optics would add cost and complexity without improving the use case. For infrastructure teams that need dependable 800G connectivity with disciplined cable management, this model fits the brief.
