Product Features
Technical Overview
This Axiom DAC cable utilizes a twinaxial design, which combines two coaxial conductors within a single cable to support high-speed data transmission with minimal signal loss over short distances. The passive architecture means it does not require external power, simplifying deployment and reducing points of failure in network infrastructure.
With a precise length of 3.3 ft (1 meter), this cable is optimized for rack-to-rack or within-rack connections in data centers, server rooms, and network closets. The SFP+ connectors are keyed for proper orientation and provide a robust mechanical connection that resists accidental disconnection.
Key Product Advantages
The Axiom J9281B-AX offers several distinct advantages for network administrators and IT professionals seeking reliable high-speed connectivity. Its passive twinaxial design delivers 10 Gigabit performance without the complexity and cost of active optical cables or separate transceivers.

Deployment / Use Cases
This DAC cable is specifically designed for short-reach 10 Gigabit Ethernet connections in enterprise and data center environments. Its 3.3 ft length makes it ideal for connecting adjacent equipment within the same rack or between neighboring racks in high-density server deployments.
Common deployment scenarios include connecting top-of-rack switches to servers, linking aggregation switches in network closets, and establishing high-speed connections between storage arrays and servers. The cable's passive design makes it particularly suitable for environments where power efficiency and reliability are priorities, as it contains no active electronics that could fail or require cooling.
Data Center Server Connections
Connect servers to top-of-rack switches within the same cabinet for high-performance computing and storage applications.
Network Aggregation Links
Establish 10G links between switches in network closets or between distribution and core switches in enterprise networks.

FAQ
What is the maximum distance this DAC cable can support?
This Axiom 10GBASE-CU SFP+ Passive DAC Twinax Cable is designed for short-reach connections up to approximately 10 meters, though this specific model is 3.3 ft (1 meter) long. Twinaxial DAC cables are typically used for connections within the same rack or between adjacent racks in data center environments where distances are minimal but high-speed performance is critical.
Is this cable compatible with non-HP networking equipment?
While specifically designed and tested for HP compatibility, this SFP+ DAC cable uses standard 10GBASE-CU specifications and should work with other vendors' SFP+ ports that support passive twinaxial direct attach cables. However, for guaranteed performance, it's recommended to verify compatibility with your specific network device manufacturer's documentation before deployment.
What does 'passive' mean for this DAC cable?
A passive DAC cable contains no active electronics or signal conditioning components. It uses the electrical properties of the twinaxial copper conductors to transmit signals directly between devices. This makes passive DAC cables more power-efficient, reliable, and cost-effective than active cables, though they have shorter maximum distance limitations compared to active or optical solutions.
Can I use this cable for connections longer than 3.3 ft?
No, this specific Axiom J9281B-AX model is a fixed-length 3.3 ft (1 meter) cable. For longer connections, you would need to select a different DAC cable with the appropriate length. Twinaxial DAC cables are available in various standard lengths typically ranging from 1 to 10 meters to accommodate different rack and data center layouts.
