Move 100 GbE traffic across short distances without adding optical complexity. This 3 m QSFP28 DAC cable is intended for Intel/Ruckus-compatible ports in dense infrastructure where adjacent switches, servers, or appliances need a direct, high-speed connection. By using direct attach copper, it keeps the link simple while supporting the throughput expected in modern aggregation and leaf-spine environments. For enterprise teams, DAC is often the right answer when the run is short and the requirement is strict. You avoid separate transceivers, reduce power consumption, and keep latency low. The 3 m length gives enough flexibility for rack layouts and cross-connects while staying within the practical range where copper interconnects make the most sense. This cable fits environments that value predictable deployment and clean cable management: data centers, network closets, and staging labs standardizing on QSFP28 connectivity. When the goal is to connect high-speed equipment without overspending on optics, this compatible DAC delivers a focused, cost-aware path to 100 GbE.
