Keep short-reach infrastructure links simple, fast, and predictable with this 2.5 m QSFP-DD DAC cable from Axiom. Built for Mellanox-compatible environments, it delivers direct attach copper connectivity for high-bandwidth links where optical modules are unnecessary overhead. For data center teams, DAC is often the right answer when the run stays inside the rack or across adjacent racks. You get a lower-power interconnect with fewer components to manage, fewer points of failure, and a cleaner bill of materials. That matters when you are scaling ports across top-of-rack switches, leaf-spine fabrics, or high-density compute clusters. This cable is a strong fit when procurement needs to control cost without compromising link integrity. Compared with optical alternatives, it reduces transceiver count and simplifies deployment while preserving the performance profile expected in modern 400G-class environments. The 2.5 m length gives you added routing flexibility for structured cabling in tight enclosures and mixed-depth racks. Choose this cable when the priority is dependable short-distance throughput, efficient power use, and straightforward installation in Mellanox-based networks.
