Axiom QSFP-DD DAC Cable for Cisco 3m | QSFP-DD, 400G, DAC — QDD-4ZQ100-CU3M-AX

When a short copper run needs a little more reach, this 3 m QSFP-DD DAC cable keeps the design straightforward. The Axiom QSFP-DD DAC Cable for Cisco 3 m is built for direct attach connectivity in high-density environments where predictable performance matters more than optical flexibility. By using copper instead of transceivers and fiber, it helps reduce power consumption, simplify procurement, and keep port planning clean. The 3 m length is well suited to adjacent-rack and cross-rack connections where a 1 m cable would be too short but optics would be unnecessary. That makes it a strong fit for top-of-rack switching, aggregation layers, and storage or compute fabrics that rely on short, direct interconnects. Cisco-aligned compatibility supports enterprise standardization, while the DAC design helps minimize latency and operational overhead. For infrastructure teams building dense fabrics with disciplined cable management, this cable offers the right amount of reach without adding complexity. It is a practical, cost-aware choice for high-speed links that stay close to the rack. Ideal For Adjacent-rack switch-to-switch links Top-of-rack to server connections with extra slack Storage fabric interconnects across nearby racks Aggregation-layer cabling in Cisco-based data centers Why This Product 1 3 m reach for more flexible rack-to-rack routing 2 Direct attach copper keeps short links simple 3 Cisco-aligned compatibility for enterprise fabrics 4 Better fit than 1 m cables when extra slack is needed
