HPE 1m 100GbE QSFP28 to 4x25GbE SFP28 Copper Cable

The HPE Q9S72A is a 1 meter Direct Attach Copper cable that links one 100 Gigabit Ethernet QSFP28 port to four 25 Gigabit Ethernet SFP28 ports. It lets you aggregate or break out bandwidth inside the rack without the cost and complexity of optical transceivers.

This passive copper design moves data at line rate, up to 100 Gbps in total or 25 Gbps on each individual lane, with virtually no added latency. It is a practical choice when you need to connect a top-of-rack switch to servers, storage arrays, or network adapters that reside in the same cabinet.

Administrators who manage dense virtualized environments, high-performance computing clusters, or cloud platforms will appreciate the low power draw and simplified cable management. At just one meter, the cable keeps signal paths short, helps airflow, and avoids the slack that can clutter rack space.

Compliance with the SFF-8665 specification ensures predictable interoperability with HPE networking hardware and other devices that follow the same standard. Installation is straightforward: plug the QSFP28 side into the switch, snap the four SFP28 ends into compatible ports, and the link is ready for traffic.

For organizations looking to scale bandwidth quickly while controlling expenses, this cable provides a solution that is both reliable and cost effective when compared with fiber alternatives.
