Product Features
Technical Overview
This DAC cable adheres to the 40GBASE-CR4 and 10GBASE-CU standards, ensuring interoperability with compliant QSFP+ and SFP+ ports. The twinaxial cable construction provides robust electrical performance, minimizing crosstalk and signal attenuation for reliable 40GbE and 10GbE throughput. The passive architecture means no signal retiming or active electronics, resulting in lower latency and power draw compared to active optical cables or transceiver-based solutions.
The cable features one QSFP+ connector on the first end and four SFP+ connectors on the second end, enabling a single 40GbE port to break out into four 10GbE links. This configuration is particularly useful for connecting high-density switches to servers or storage arrays, optimizing port utilization and simplifying cable management. The 16.4 ft length offers flexibility in rack-to-rack or within-rack deployments, supporting typical data center layouts.
Key Product Advantages
The Axiom 10322-AX delivers significant advantages for network deployments requiring high-speed, short-reach connectivity. Its passive twinaxial design reduces total cost of ownership by eliminating the need for separate optical transceivers and fiber cabling, while providing a durable, plug-and-play solution that minimizes installation time and maintenance overhead.
Cost-Effective High-Speed Links
By using copper twinaxial cabling instead of optical components, this DAC cable offers a lower-priced alternative for 40GbE and 10GbE connections without sacrificing performance, ideal for budget-conscious deployments.
- No transceivers required
- Reduces fiber optic costs
- Lower power consumption
Simplified Network Architecture
The breakout configuration from one QSFP+ port to four SFP+ ports streamlines cabling in dense environments, reducing clutter and improving airflow in racks while maintaining high throughput.
- Consolidates multiple cables
- Improves rack organization
- Supports high-density setups
Reliable and Durable Build
With a lifetime warranty and robust twinaxial construction, this cable ensures long-term reliability in demanding data center conditions, resisting electromagnetic interference and physical wear.
- Lifetime warranty coverage
- EMI-resistant design
- Durable connectors
Deployment / Use Cases
This cable is engineered for specific networking scenarios where short-reach, high-bandwidth connections are critical. Its 40GbE to 4x10GbE breakout capability makes it particularly valuable in modern data center and enterprise network topologies that require efficient port utilization and scalable bandwidth.
Common use cases include connecting top-of-rack switches with 40GbE uplinks to servers or storage devices with 10GbE interfaces, enabling cost-effective spine-leaf architectures. It also supports network aggregation points where a core switch needs to distribute bandwidth to multiple access switches, or in high-performance computing clusters requiring low-latency interconnects. The 16.4 ft length accommodates typical rack distances, making it suitable for within-rack or adjacent-rack deployments without the complexity of fiber management.

FAQ
What is the maximum distance supported by this DAC cable?
This Axiom 10322-AX twinaxial cable supports a reach of up to 5 meters (16.4 ft), which is typical for passive direct-attach copper cables under the 40GBASE-CR4 and 10GBASE-CU standards. It is designed for short-range connections within racks or between adjacent racks in data centers, providing reliable high-speed links without the need for optical transceivers.
Can this cable connect a 40GbE switch port to four 10GbE server ports?
Yes, the cable features one QSFP+ connector on one end and four SFP+ connectors on the other, allowing a single 40GbE QSFP+ port on a switch to break out into four independent 10GbE SFP+ links. This is ideal for connecting high-density switches to multiple servers or storage devices, optimizing port usage and reducing cabling complexity in spine-leaf or aggregation scenarios.
Does this DAC cable require external power or configuration?
No, this is a passive DAC cable, meaning it does not require external power or configuration. It operates as a plug-and-play solution, with no active electronics for signal retiming. This results in lower latency, reduced power consumption, and simpler deployment compared to active optical cables or transceiver-based setups, making it a straightforward choice for short-reach connections.
What types of devices are compatible with this cable?
The cable is compatible with routers, switches, and network devices that support QSFP+ and SFP+ interfaces adhering to the 40GBASE-CR4 and 10GBASE-CU standards. It is designed for use in enterprise and data center environments where high-speed Ethernet connectivity is needed, and it should work with most major networking equipment brands that implement these standard interfaces.
