Keep high-speed infrastructure close to the switch with a 2 m QSFP28 direct attach copper cable engineered for 100GBASE-CR4 links. This NVIDIA Mellanox compatible assembly is designed for short-reach interconnects where predictable latency, simple deployment, and lower power draw matter more than optical flexibility. By using passive copper instead of transceivers and fiber, it reduces cost and complexity at the port level while preserving 100 GbE throughput across adjacent racks or within the same cabinet. The no-FEC design aligns with environments that already validate link integrity at the switch and host layer, helping maintain clean, deterministic connectivity in dense fabrics. For procurement teams, the value is in matching performance to distance. At 2 m, this cable is sized for direct switch-to-server or switch-to-switch runs without excess slack, which helps keep cable management controlled in high-density enclosures. TAA compliance also supports public sector and regulated purchasing requirements. When the application calls for dependable 100 GbE transport in a short-reach footprint, this DAC delivers the right balance of speed, simplicity, and deployment discipline.
