The HPE Aruba Networking J9281D is a high-performance 10G SFP+ to SFP+ Direct Attach Copper (DAC) cable engineered for reliable short-range high-speed connectivity between switches, servers, and storage devices in enterprise and data center environments.

This passive twinax copper cable features permanently attached SFP+ connectors on both ends and supports data rates up to 10Gbps, making it ideal for top-of-rack (ToR) switching, server aggregation, storage networking, and high-density enterprise deployments. The compact 1-meter cable length provides a cost-effective and low-latency alternative to optical transceivers for short-distance interconnects.

Designed for Aruba and compatible HPE networking platforms, the J9281D offers hot-pluggable installation, low power consumption, reduced electromagnetic interference, and enterprise-grade reliability for mission-critical network infrastructure.
