StarTech QSFPH40GCU05 0.5 m 40 Gbps Direct Attach Cable

Short links deserve purpose-built cabling. The StarTech QSFPH40GCU05 is a 0.5 m 40 Gbps direct attach cable designed for compact interconnects in high-density network environments. Its Cisco QSFP-H40G-CU0-5M compatibility makes it a practical choice for teams standardizing on short-reach 40 GbE connections across supported equipment. At half a meter, this cable is built for the tight spaces where excess length becomes a liability. It helps reduce cable clutter, keeps airflow paths cleaner, and supports orderly port-to-port routing in adjacent switch, server, and storage deployments. For rack builders and network operators, that translates into faster installation and cleaner maintenance. This is the kind of cable you choose when the design brief is precision, not flexibility. In dense infrastructure, a shorter direct attach cable can improve physical organization and make port mapping easier to manage. For environments where every connection is deliberate, this model delivers a focused, short-run 40 Gbps path without unnecessary slack.
