Maintain high-speed rack-to-rack connectivity without adding transceivers, patch panels, or extra optical components. This 5 m direct attach copper cable is designed for 40 GbE environments that need predictable latency and straightforward deployment in compact infrastructure layouts. The QSFP+ to 4 x SFP breakout format supports mixed-port connectivity where a single high-speed uplink must fan out to multiple SFP-based endpoints. For teams standardizing HP X240-based switching or adjacent equipment, this cable helps simplify short-distance interconnects while keeping signal paths direct. It is well suited for top-of-rack and aggregation designs where cable management, port density, and cost control matter. Compared with optical alternatives, DAC cabling reduces the number of components in the link and can shorten deployment time. Use it where you need dependable short-reach performance between network devices in the same row or cabinet cluster. The 5 m length gives added routing flexibility for clean installations without overextending the cable path. For infrastructure teams balancing performance and procurement discipline, this is a focused, purpose-built interconnect for 40 GbE breakout applications.
