HPE Aruba Networking 100G QSFP28 to QSFP28 1m Direct Attach Copper Cable

The HPE R0Z25A is a direct attach cable that measures 1 meter and carries 100 gigabit signals through QSFP28 connectors on both ends. It links devices within the same rack, providing a straightforward way to move high-bandwidth traffic without the extra cost or complexity of optical transceivers.

The cable plugs directly into compatible HPE Aruba switches such as the 8325-32C and 8325-48Y8C. Because it relies on copper conductors, latency stays low and power draw remains modest, a combination valued by data centers that need both speed and efficiency.

Use it to stack switches, create leaf-spine links, or connect a high-performance server to a top-of-rack switch. Installation involves nothing more than seating the QSFP28 ends, and the fixed 1 meter length helps keep cable management clean while minimizing signal loss on very short runs.

The assembly arrives as a single unit, has an outer jacket in black, and weighs about 122.5 grams. Once in place, it delivers reliable 100 G throughput backed by the quality standards of HPE networking hardware.
