HPE 100G QSFP28 Direct Attach Cable

This HPE R0Z25A cable provides a 100 Gbit/s link between two QSFP28 ports. It suits data-centre racks and high-performance clusters that need short-reach copper connectivity. The 3.28 ft length keeps latency low inside a single cabinet. Multi-colour jacketing helps technicians trace links quickly.

Verify QSFP28 Ports And Clearance

Confirm both devices present QSFP28 interfaces before ordering. Check that the 0.27 lb cable weight and bend radius fit your cable-management trays. Ensure the 3.28 ft reach matches the rack layout without excess slack. No adapter is included for other form factors.

Replaces Longer Or Lower-Speed Copper Links

This cable upgrades 10 Gbit/s or 25 Gbit/s direct-attach runs that now limit throughput. It also replaces longer passive copper assemblies that exceed the 3.28 ft design target and risk signal degradation. The jump is worth it when 100 Gbit/s density is required within a single rack.

Questions about this item

Does the 3.28 ft cable ship with both QSFP28 ends attached, or must I buy the connectors separately?

The cable arrives as a single assembly with a QSFP28 connector on each end; no separate connectors are required.

The listing shows 100 Gbit/s — is that the only speed this QSFP28 cable supports, or are lower rates available?

The cable is rated for 100 Gbit/s and will also operate at lower Ethernet speeds negotiated by the connected ports.

At 0.27 lb, is the 3.28 ft copper cable light enough for dense switch stacking without stressing the ports?

At roughly 0.27 lb the cable is lightweight, reducing mechanical strain on switch ports in high-density deployments.
