HPE JH235A X242 40G QSFP+ to QSFP+ 3m DAC Cable

Use this HPE X242 direct attach cable to build short 40 GbE links with less overhead and fewer components. The QSFP+ to QSFP+ design is made for direct port-to-port connectivity, which is ideal when switches, routers, or other network appliances sit within the same rack or adjacent racks. At 3 m, it gives you enough reach for practical cable management without introducing unnecessary slack. For infrastructure teams, DAC is often the right choice when the job is to move traffic cleanly between nearby ports. It reduces the number of parts in the path, simplifies procurement, and keeps installation time low. That matters in dense environments where every rack unit and every cable bend radius affects serviceability. As an Aruba-branded HPE cable, this assembly fits environments that standardize on HPE networking hardware and want a direct, vendor-aligned interconnect for 40 GbE deployments. It is a straightforward answer for short-range, high-speed links where reliability and simplicity matter more than optics.
