Product Features
Technical Overview
This DAC cable operates on the 40GBASE-CR4 standard, utilizing a passive copper twinaxial design to deliver 40 Gbit/s throughput over a 1-meter distance. The QSFP+ connectors on both ends provide a hot-pluggable interface that supports high-density network environments.
The passive architecture means the cable does not require external power, relying instead on the host device's port power for signal transmission. This design reduces power consumption and heat generation compared to active optical cables, making it ideal for energy-efficient network deployments.
Key Product Advantages
This DAC cable simplifies network connectivity by providing a direct, plug-and-play solution for 40GbE links. Its passive design ensures reliable performance without additional power requirements, while the Cumulus compatibility offers seamless integration into modern network ecosystems.
Cost-Effective Connectivity
Eliminates the need for separate optical transceivers and fiber patch cables, reducing both initial hardware costs and ongoing maintenance expenses.
- No external power needed
- Lower total cost of ownership
- Reduced component count
High-Density Deployment
The compact QSFP+ form factor supports high-port-density switches and routers, maximizing rack space utilization in data center environments.
- Hot-pluggable design
- Standard QSFP+ footprint
- Space-efficient cabling
Deployment / Use Cases
This cable is ideal for connecting network switches, routers, and servers within the same rack or adjacent racks in data center environments. The 1-meter length makes it perfect for top-of-rack switching configurations where minimal cable management is desired.
Common deployment scenarios include spine-leaf network architectures, high-performance computing clusters, and storage area networks requiring 40GbE connectivity. The Cumulus compatibility specifically targets software-defined networking environments where consistent hardware performance is critical.
Data Center Interconnects
Connect leaf switches to spine switches within the same rack row, providing low-latency 40GbE links for east-west traffic flows.
Server-to-Switch Connections
Link high-performance servers directly to top-of-rack switches, ensuring maximum throughput for compute-intensive applications.

FAQ
What is the maximum data transfer rate of this DAC cable?
This cable supports data transfer rates up to 40 Gbit/s, compliant with the 40GBASE-CR4 standard. It provides full 40GbE bandwidth for high-performance network connections between compatible devices.
What does 'passive' mean for this DAC cable?
Passive means the cable does not contain active electronic components that require external power. It relies on the host device's port power for signal transmission, resulting in lower power consumption, reduced heat generation, and generally higher reliability compared to active cables.
What network devices is this cable compatible with?
The cable features QSFP+ connectors that are compatible with standard 40GbE network device ports. It is specifically tested for compatibility with Cumulus networking platforms and works with any network device supporting 40GBASE-CR4 QSFP+ interfaces.
What is the cable length and why is 1 meter optimal?
The cable is 1 meter (3.3 feet) long, which is ideal for connecting equipment within the same rack or adjacent racks in data center environments. This length minimizes cable clutter while providing sufficient reach for top-of-rack switching configurations.
