Keep high-speed infrastructure tightly connected with a 2 m direct attach copper cable built for 400GBASE-CR8 deployments. This NVIDIA Mellanox compatible assembly links an OSFP finned-top port to two QSFP56 endpoints, giving you a practical way to extend 400 GbE connectivity across adjacent racks or within the same cabinet. For environments where every watt, port, and millisecond matters, DAC remains the cleanest answer for short-reach interconnects. It avoids the added expense and thermal load of optics while preserving the signal integrity expected in modern high-density fabrics. That makes it a strong fit for leaf-spine switching, accelerated compute clusters, and storage networks that need predictable short-distance performance. The 2 m length gives teams enough reach for tidy cable routing without introducing unnecessary slack. In procurement terms, this cable helps standardize short-run 400G links at a lower total cost than optical alternatives, while keeping installation simple and maintenance straightforward. It is a focused choice for infrastructure teams that want dependable connectivity in the most demanding rack-level deployments.
