Extreme Networks 100G Passive DAC QSFP28 3 m | QSFP28, Twinax

Support short-reach 100G interconnects with a 3 meter passive DAC QSFP28 cable. This direct-attach copper design is well suited to top-of-rack and adjacent-rack connections where simplicity, low latency, and predictable deployment matter more than long-distance reach. Passive DAC is a strong fit for high-density switching environments because it removes the need for separate optics on both ends. That can lower total link cost, reduce power consumption, and simplify spare management across large switch fabrics. For teams building out data center racks, lab environments, or aggregation layers, a 3 meter length gives enough reach for clean routing while staying tight enough for efficient cable management. Compared with optical alternatives, this cable is the practical choice when the link stays inside the rack row or between nearby cabinets. It is built for the kind of short, high-speed connection where direct attach copper delivers the right balance of performance and operational efficiency.
