Keep high-speed links simple where distance is measured in racks, not meters. The INTELLINET QSFP+ 40G Passive DAC Twinax Cable provides a direct copper path for 40 GbE connections between compatible QSFP+ ports, making it a practical choice for short-reach data center interconnects. Passive DAC design avoids the added cost and power draw of optical transceivers while still delivering the bandwidth needed for aggregation, leaf-spine, and storage networking. That makes it especially useful in environments where port density, thermal load, and procurement discipline matter. Use it to connect switches to servers, top-of-rack equipment to adjacent cabinets, or storage arrays to network fabrics with a cable built for predictable short-distance performance. For teams standardizing on QSFP+ infrastructure, this cable helps keep deployments clean, efficient, and easier to service. When the requirement is reliable 40 Gbps connectivity without unnecessary optics, this cable fits the job with the right balance of simplicity and value.
