100G Passive DAC QSFP28 0.5m Extreme Networks | QSFP28, DAC

Keep short 100G interconnects simple with a passive direct attach cable designed for QSFP28 ports. At 0.5 m, this cable is built for close-proximity switch connections inside the same rack or adjacent equipment, where optical modules add cost and complexity without delivering a practical advantage. Passive DACs are a strong fit for dense network fabrics because they reduce power draw, remove transceiver pairing concerns, and keep cabling straightforward. For top-of-rack and leaf-spine environments, that means fewer components to manage and a cleaner path between devices. This 100G passive DAC is the right choice when the requirement is direct, short-reach connectivity with predictable behavior. It supports the kind of tightly controlled infrastructure where every port, every cable, and every watt matters.
