Aruba JL488A 25G SFP28 to SFP28 3 m DAC Cable

Use direct attach copper where optical optics are unnecessary and short-reach performance is the priority. This Aruba 25G SFP28 to SFP28 DAC cable is designed for 3 m interconnects between compatible SFP28 ports, giving network teams a straightforward way to link switches, servers, and storage within the rack or across adjacent racks. DAC cabling is often selected when procurement wants to reduce the number of separate transceivers and simplify the bill of materials. In dense environments, that matters. Fewer components mean fewer points to source, stage, and manage, while the fixed-length copper assembly keeps the physical layer predictable. For enterprise infrastructure teams, the value is in the balance: 25G throughput, SFP28 compatibility, and a short 3 m reach that fits real rack layouts without excess slack. It is a practical choice for environments that need dependable short-haul connectivity and want to keep the network edge clean, contained, and easy to service.
