Keep aggregation layers moving with a direct-attach cable designed for 100 GbE breakout between Cisco and Dell compatible platforms. This 3 m QSFP28 to 4x SFP28 assembly supports 100GBASE-CR4 connectivity, giving infrastructure teams a practical way to fan out a single 100 GbE uplink into four 25 GbE paths without adding optics, patch panels, or extra power draw. For top-of-rack and leaf-spine environments, that matters. Passive DAC construction helps reduce cost and complexity while preserving the short-reach performance expected inside the rack or between adjacent racks. The 3 m length gives enough slack for orderly routing in dense cabinets, while the TAA compliant build supports procurement requirements in regulated environments. Choose this cable when you need deterministic short-distance connectivity, vendor compatibility across Cisco and Dell ecosystems, and a cleaner bill of materials than optical alternatives. It is a straightforward fit for teams standardizing on 25 GbE server links while preserving 100 GbE uplink capacity at the switch edge.
