Keep short-reach 40 GbE links clean, predictable, and cost-controlled with this AddOn direct-attach copper cable. Built for QSFP+ to QSFP+ connectivity, it is designed for environments that need dependable switch-to-switch, switch-to-server, or top-of-rack interconnects without the added complexity of separate transceivers and fiber patching. At 5 m, this cable fits the common distances found inside racks and across adjacent cabinets, making it a practical choice for dense data center layouts. Direct-attach copper is often preferred for these runs because it delivers a straightforward physical layer, lower power draw than optical alternatives, and fewer components to manage in procurement and spares planning. The TAA-compliant design supports government and regulated purchasing requirements, while the HP JG327A compatibility helps simplify replacement planning for installed environments using that platform. For teams standardizing on 40 GbE, this cable offers a clean way to preserve port density and keep deployment overhead low. It is a focused, purpose-built interconnect for infrastructure teams that value reliability, compatibility, and predictable cost per link.
