Product Features
Technical Overview
This DAC cable adheres to the 40GBASE-CR4 and 10GBASE-CU standards, providing a cost-effective and straightforward method for 40GbE to 10GbE connectivity. The QSFP+ end features a single high-density connector that interfaces with 40GbE ports, while the breakout end terminates in four SFP+ connectors, each capable of 10GbE throughput. The twinaxial cable medium offers excellent signal integrity over its 1.6 ft length, suitable for top-of-rack deployments and direct device interconnections.
The passive architecture means the cable does not require external power or signal conditioning electronics, relying on the host device's port capabilities for operation. This simplifies installation and reduces points of failure. The cable is designed to be hot-pluggable, supporting live insertion and removal in compatible networking equipment without disrupting other connections.
Key Product Advantages
This Axiom DAC cable delivers significant advantages for network infrastructure by streamlining connectivity and reducing complexity. Its breakout design eliminates the need for multiple individual cables and transceivers, saving rack space and lowering overall deployment costs. The passive twinaxial construction ensures durability and consistent performance in demanding data center environments.
High-Density Connectivity
Enables a single 40GbE port to support four 10GbE connections, maximizing port utilization and simplifying cable management in crowded network racks.
- 1 QSFP+ to 4 SFP+ breakout
- Reduces cable clutter
- Optimizes switch port usage
Cost-Effective Solution
Offers a more affordable alternative to active optical cables or separate transceivers with fiber, providing reliable short-reach connectivity without sacrificing performance.
- Lower total cost of ownership
- No separate transceivers needed
- Passive design reduces power draw
Deployment / Use Cases
This cable is ideally suited for data center and enterprise networking scenarios where high-speed, short-reach connections are required. It facilitates efficient aggregation of 10GbE links into a 40GbE uplink, supporting scalable network architectures and improved bandwidth management.
Common use cases include connecting top-of-rack switches to aggregation switches, linking servers with 10GbE NICs to 40GbE switch ports, and integrating storage arrays into high-performance networks. Its Dell compatibility ensures reliable operation with a wide range of Dell networking equipment, making it a versatile choice for heterogeneous IT environments.
Data Center Interconnect
Use for spine-leaf network topologies, where leaf switches with 10GbE server connections aggregate traffic to spine switches with 40GbE ports, enhancing network throughput and reducing latency.
Server and Storage Connectivity
Connect servers equipped with 10GbE network interface cards to 40GbE switch ports, or link storage devices to network switches, supporting high-speed data transfer for virtualization and big data applications.

FAQ
What is the purpose of this QSFP+ to SFP+ breakout cable?
This cable converts a single 40 Gigabit Ethernet QSFP+ port into four 10 Gigabit Ethernet SFP+ ports. It allows you to aggregate multiple 10GbE connections into a higher-bandwidth 40GbE link, which is useful for connecting servers, switches, or storage devices in data centers where port density and bandwidth efficiency are priorities.
What does 'passive DAC' mean for this cable?
Passive DAC stands for Passive Direct Attach Copper. It means the cable does not contain active electronics for signal conditioning or retiming. It relies on the host device's port capabilities to drive signals over the copper twinaxial wires. This results in lower power consumption, reduced latency, and a simpler, more cost-effective design compared to active optical cables or active DACs.
Is this cable compatible with Dell networking equipment?
Yes, this Axiom cable is specified as Dell compatible. It is designed to work with Dell switches, routers, and other networking devices that support 40GBASE-CR4 QSFP+ and 10GBASE-CU SFP+ standards. Always verify compatibility with your specific Dell model, but it is engineered for reliable operation in Dell-based network environments.
What is the maximum distance this cable can support?
This twinaxial cable is 1.6 ft (approximately 0.5 meters) in length and is designed for very short-reach applications, typically within a single rack or between adjacent racks in a data center. Twinaxial DAC cables are generally used for distances up to 5-7 meters, but this specific 1.6 ft version is optimized for ultra-short connections where minimal cable length is required.
