ALLNET SFP+ 10G Direct Attach Copper Cable, 1m, HP/Aruba J9281D-C Compatible

Data center engineers connecting servers to top-of-rack switches or linking switches over short distances need a reliable, low-latency 10 Gigabit link. This ALLNET direct attach copper (DAC) cable provides a 1-meter passive twinax connection with SFP+ connectors on both ends, engineered for compatibility with HP and HPE Aruba networking equipment, including the J9281D-C part number.

Key specifications

• Length: 1 m (3.3 ft)
• Connector type: SFP+ to SFP+
• Cable type: Passive twinax copper
• Data rate: 10 Gigabit Ethernet
• Compatible OEM part number: HP J9281D-C
• Wire gauge: 30 AWG
• Impedance: 100 Ohm
• Operating temperature: 0°C to 70°C
• Colour: Black

Why choose it

Passive DAC cables consume less than 0.1W, reducing power and cooling costs compared to optical transceivers. The integrated SFP+ connectors eliminate the need for separate optics and fiber patch cords, simplifying deployment and lowering total cost for short-reach 10G links.

Ideal use cases

• Server to top-of-rack switch connectivity
• Switch-to-switch stacking or uplinks within a rack
• High-performance computing clusters requiring low latency
• Storage area networks (SAN) over short distances

Good to know

This cable is hot-swappable and MSA compliant, ensuring interoperability with a wide range of SFP+ ports. It is designed for data center environments with operating temperatures from 0°C to 70°C.
