Product Features
Technical Overview
This cable adheres to the 40GBASE-CR4 and 10GBASE-CU standards, supporting a total data transfer rate of 40 Gbit/s aggregated across four 10 Gbit/s lanes. The QSFP+ connector on one end interfaces with 40GbE switches or adapters, while the four SFP+ connectors on the opposite end connect to 10GbE devices such as servers, storage arrays, or additional switches.
The passive DAC architecture relies on the host equipment's electrical signaling, making it a plug-and-play solution that requires no configuration or management. Its 24 AWG gauge provides optimal conductivity and durability, suitable for rack-to-rack or within-rack deployments where minimal latency and high reliability are critical.
Key Product Advantages
This DAC cable simplifies high-speed network deployments by reducing cable clutter and eliminating the need for separate transceivers and fiber patches. Its breakout capability allows a single 40GbE port to serve multiple 10GbE devices, optimizing port utilization and reducing hardware costs.
Cost-Effective Aggregation
By converting one QSFP+ port to four SFP+ ports, it maximizes existing switch investments and minimizes the need for additional networking hardware.
- Reduces transceiver costs
- Lowers power consumption
- Simplifies cable management
Reliable Passive Operation
The passive design ensures zero configuration, no external power requirements, and consistent performance without active component failures.
- No heat dissipation issues
- Plug-and-play installation
- Long-term durability
Deployment / Use Cases
This cable is ideal for data centers, enterprise network cores, and high-performance computing environments where 40GbE uplinks need to distribute bandwidth to multiple 10GbE endpoints. Common applications include connecting top-of-rack switches to server racks, linking aggregation switches to access layers, or integrating storage networks with high-speed backbones.
Its Juniper compatibility ensures seamless integration with Juniper QFX series switches and other supported platforms, providing a reliable interconnect for virtualized infrastructures, cloud deployments, and media streaming services. The 16.4-foot length accommodates typical rack spacing while maintaining signal quality.
Data Center Interconnect
Use for spine-leaf architectures where 40GbE spines connect to 10GbE leaf switches, ensuring low-latency, high-throughput fabric.
Server Aggregation
Connect a 40GbE switch port to multiple 10GbE servers or storage devices, optimizing bandwidth allocation and reducing port congestion.

FAQ
What is the purpose of this QSFP+ to SFP+ DAC cable?
This cable aggregates four 10GbE SFP+ connections into a single 40GbE QSFP+ port, enabling efficient bandwidth distribution in data centers. It allows network administrators to connect multiple 10GbE devices, such as servers or storage units, to a 40GbE switch without needing separate transceivers or fiber cables, reducing cost and complexity.
Is this cable compatible with Juniper networking equipment?
Yes, the Axiom QFX-QSFP-DACBO-5M-AX is specifically designed for compatibility with Juniper devices, particularly QFX series switches. It adheres to Juniper's electrical and mechanical specifications, ensuring reliable performance and seamless integration in Juniper-based network environments without requiring additional configuration.
What does 'passive DAC' mean for this cable?
Passive DAC indicates that the cable uses copper conductors without active signal amplification or retiming electronics. It relies on the host equipment's electrical signaling, resulting in a plug-and-play solution that requires no external power, generates minimal heat, and offers a cost-effective, low-latency connection for short-reach applications up to 5 meters.
What is the maximum data transfer rate supported?
This cable supports a total data transfer rate of 40 Gbit/s, achieved by aggregating four 10 Gbit/s lanes. It complies with the 40GBASE-CR4 standard for the QSFP+ end and 10GBASE-CU for the SFP+ ends, ensuring full bandwidth utilization for high-speed networking tasks like data aggregation, virtualization, and storage access.
