Keep high-speed links simple where distance is short and reliability matters. This HPE JD094B-BX40-U compatible SFP+ module is a 3 m passive direct-attach cable designed for 10 GbE connections between network devices in the same rack or adjacent racks. Twinaxial construction supports low-latency data transfer while avoiding the added expense of separate optics and fiber patching. For infrastructure teams standardizing on SFP+ ports, DAC cabling is often the cleanest way to connect switches, servers, and storage appliances. This cable is programmed and tested for compatibility with supported network hardware, helping reduce deployment risk during refreshes, expansions, and lab builds. The passive design also keeps power draw and heat to a minimum, which is useful in dense environments where every watt and every cable matters. Choose this option when you need dependable 10 Gbit/s connectivity with a straightforward install path and no unnecessary components. It is a practical fit for short interconnects where performance, compatibility, and predictable operation matter more than distance.
