Keep high-density 40 GbE interconnects straightforward with this AddOn direct attach cable. Built as an IBM 49Y7887 compatible 40GBASE-CU QSFP+ to 4xSFP+ solution, it is designed for short-reach fan-out connectivity where a single QSFP+ port must break out to multiple SFP+ endpoints. That makes it a practical fit for migration paths, aggregation layers, and rack-level designs that need to connect newer 40 GbE hardware to multiple 10 GbE devices. By using copper direct attach instead of separate transceivers and fiber assemblies, teams can reduce component count, simplify ordering, and keep cable management tighter in crowded cabinets. The TAA-compliant construction supports procurement requirements in regulated environments, while the AddOn compatibility focus gives infrastructure teams a dependable alternative to OEM cabling. For organizations standardizing on repeatable, short-distance interconnects, this cable helps preserve port density and deployment speed without introducing unnecessary complexity. It is the kind of cable you choose when the connection must be clean, predictable, and easy to support at scale.
