Product Features
Technical Overview
This cable implements the 40GBASE-CR4 Ethernet standard over twinaxial copper, delivering 40 Gbit/s full-duplex bandwidth across four lanes. The passive design means no signal conditioning or retiming electronics are built into the cable assembly, making it ideal for connections under 5 meters where signal integrity remains strong.
The QSFP+ connectors feature a latching mechanism for secure attachment and support hot-pluggable installation in compatible QSFP+ ports. While coded for Juniper network platforms, this cable typically works with any device that accepts standard 40GBASE-CR4 QSFP+ DAC cables, though platform-specific compatibility should always be verified.
Key Product Advantages
This DAC cable eliminates the need for separate transceivers and fiber patch cables, reducing both cost and complexity in 40GbE deployments. The passive twinaxial design provides lower latency and power consumption compared to active optical solutions while maintaining full 40 Gbit/s throughput.
Cost-Effective 40GbE Connectivity
Delivers 40 Gigabit Ethernet performance without the expense of optical transceivers and fiber cabling, making it an economical choice for short-distance interconnects.
- No separate transceivers needed
- Lower total cost than optical solutions
- Simplifies inventory management
Plug-and-Play Installation
The passive design requires no configuration or management, allowing for immediate deployment once physically connected between compatible QSFP+ ports.
- No external power required
- Hot-pluggable support
- Minimal setup time
Deployment / Use Cases
This cable is ideal for connecting network devices within the same rack or adjacent racks in data center environments. Common applications include linking top-of-rack switches to servers, connecting aggregation switches, or establishing inter-switch links in high-performance computing clusters.
The 3-meter length provides flexibility for routing within standard 19-inch racks while maintaining signal integrity. This makes it suitable for most intra-rack connections where devices are positioned within the same cabinet or immediately adjacent cabinets in modern data center layouts.
Data Center Interconnects
Connect leaf and spine switches in Clos architectures or link servers to top-of-rack switches for 40GbE server connectivity.
High-Performance Computing
Establish low-latency connections between compute nodes or storage arrays in HPC environments requiring 40 Gigabit throughput.

FAQ
What is the maximum recommended distance for this passive DAC cable?
Passive DAC cables like this Axiom 40GBASE-CR4 QSFP+ model are typically recommended for connections up to 5 meters. The 3-meter length provided here ensures strong signal integrity without requiring signal conditioning electronics, making it ideal for intra-rack or adjacent-rack deployments in data center environments.
Does this cable work with non-Juniper network equipment?
While coded for Juniper compatibility, this 40GBASE-CR4 QSFP+ passive DAC cable generally works with any network device that accepts standard QSFP+ DAC cables. However, compatibility should always be verified with your specific equipment manufacturer, as some platforms may require vendor-specific coding or have unique electrical requirements.
What is the difference between passive and active DAC cables?
Passive DAC cables like this Axiom model contain only copper wiring with no signal conditioning electronics, making them simpler, lower power, and more cost-effective for short distances. Active DAC cables include retiming or signal boosting electronics that extend reach but add cost and power consumption. For 3-meter connections, passive cables provide optimal performance without unnecessary complexity.
