Aruba JL489A 25G SFP28 to SFP28 5 m DAC Cable

Keep short-range 25 GbE links clean, predictable, and cost-efficient with the Aruba JL489A direct-attach copper cable. Designed for SFP28-to-SFP28 connectivity over 5 m, it is a practical choice for top-of-rack switching, server uplinks, and adjacent cabinet interconnects where optical modules would add unnecessary expense and complexity. Direct-attach copper is valued in dense infrastructure because it delivers a fixed-length, low-latency path with fewer components to manage. That means fewer transceivers to source, fewer points of failure, and less power consumed at the edge of the network. For teams standardizing on Aruba switching, this cable helps preserve port density while keeping deployment straightforward. Use it where predictable short-run performance matters: between switches, from servers to access switches, or across racks in the same row. The 5 m reach gives you enough slack for clean cable routing without pushing into longer-distance optics. For environments that buy once and deploy at scale, this is the kind of cable that earns its place by reducing friction in the rack and in procurement.
