HPE Aruba Networking 10G SFP+-to-SFP+ 1 m Direct Attach Copper Cable J9281D

BRAND NEW WITH FULL HPE WARRANTY!!!

This 1-metre passive twinax direct-attach copper cable (J9281D) provides a simple, low-latency, cost-effective 10 Gigabit connection between two SFP+ ports. Ideal for short-distance links (within racks or adjacent equipment) in data centers, server rooms, or network closets. Because it uses copper twinax rather than fiber, it is a practical choice when fiber optics aren’t needed, and you want straightforward 10 GbE connectivity with minimal overhead.

Quick Tech Specs – HPE Aruba J9281D

• Connector type: SFP+ on both ends (SFP+ → SFP+) 
• Cable length: 1 m (approx. 3.3 ft) 
• Data rate: Up to 10 Gbps (10G Ethernet) 
• Media: Passive twinax copper cable (DAC) 
• Use case: Short-reach interconnection between 10G-enabled switches, servers, or network gear in same rack or adjacent racks / close distance setups

Why It Matters:

• Great for low-cost, short-distance 10G links — especially useful for connecting two devices in the same rack without needing fiber.
• Lower latency and power use compared to 10G fiber + transceivers — passive DAC cables are simpler, more power-efficient, and often cheaper.
• Plug-and-play — no configuration needed other than inserting into compatible SFP+ ports; ideal for quick deployments or upgrades.
