StarTech QSFPH40GACU7 7 m 40 GbE Direct Attach Cable

Keep high-speed links stable across longer rack-to-rack runs with this 7 m Cisco-compatible QSFP direct attach cable from StarTech. Designed for 40 GbE interconnects, it provides a practical alternative to transceivers and fiber when you need predictable short-reach performance inside the data center. The passive twinax construction helps reduce power draw and simplifies deployment, while the QSFP-to-QSFP design supports direct attachment between compatible switches, servers, and storage platforms. At 7 m, it gives infrastructure teams more reach than typical short DACs without moving to a more expensive optical path. This cable is a strong fit for environments where port density, cable management, and link stability matter. It is especially useful in top-of-rack and adjacent-rack designs where every connection must be easy to trace, quick to install, and dependable under sustained traffic. For teams standardizing on 40 GbE, it delivers the right balance of reach, simplicity, and cost control.
