The HPE JH235A is a direct attach copper (DAC) cable designed for high-speed networking applications. This cable features QSFP+ connectors on both ends, supporting 40 Gigabit Ethernet connectivity. It is suitable for connecting network devices such as switches, servers, or storage arrays within a rack or across adjacent racks, where a 3-meter reach is sufficient. The direct attach copper design offers a cost-effective and low-latency solution for high-bandwidth interconnections compared to fiber optic alternatives over short distances.
