Product Features
Technical Overview
This 40GBASE-CR4 compliant DAC cable implements the QSFP+ form factor with twinaxial copper construction. The cable supports 40 Gigabit Ethernet data rates using four lanes of 10 Gbit/s each, aggregated through the QSFP+ interface. The passive electrical design transmits signals without signal regeneration, making it ideal for connections under 7 meters in data center environments.
The cable features identical QSFP+ network connectors on both ends, each providing a 1 x QSFP+ interface. This symmetrical design ensures consistent performance whether connecting switch-to-switch, switch-to-server, or within rack-mounted configurations. The twinaxial cable construction provides excellent electromagnetic interference shielding while maintaining flexibility for cable management.
Key Product Advantages
This DAC cable offers several advantages for network administrators seeking reliable 40GbE connectivity. The passive twinaxial design eliminates the need for external power supplies or signal conditioning electronics, reducing points of failure and simplifying deployment. The cable's construction provides robust signal integrity while maintaining flexibility for tight data center installations.
Cost-Effective 40GbE Solution
Compared to optical transceiver modules with separate fiber cables, this DAC cable provides a more economical solution for short-reach 40GbE connections without sacrificing performance.
- Eliminates separate transceiver costs
- No fiber cable purchase required
- Lower total cost of ownership
HP Platform Compatibility
Engineered for compatibility with HP networking equipment, this cable ensures reliable operation in HP switch and server environments without requiring special configuration or firmware updates.
- Tested for HP compatibility
- Plug-and-play installation
- Reliable performance in HP ecosystems
Deployment / Use Cases
This 40GBASE-CR4 QSFP+ passive DAC cable is designed for data center and enterprise network environments requiring high-speed interconnects. The 16.4-foot length makes it suitable for within-rack connections, top-of-rack switching configurations, and short-distance server-to-switch links in high-density computing environments.
Common deployment scenarios include connecting 40GbE switches in spine-leaf architectures, linking servers with 40GbE network interface cards to aggregation switches, and establishing high-speed connections between storage arrays and network infrastructure. The cable's passive design makes it particularly suitable for environments where power efficiency and reliability are priorities.
Data Center Interconnects
Ideal for connecting switches within the same rack or adjacent racks in data center environments, providing 40GbE backbone connectivity for server farms and storage networks.
High-Performance Computing
Supports high-bandwidth requirements in HPC clusters, financial trading systems, and media production environments where low-latency 40GbE connections are essential.

FAQ
What is the maximum data transfer rate of this DAC cable?
This Axiom DAC cable supports a maximum data transfer rate of 40 Gbit/s, which is equivalent to 40 Gigabit Ethernet. It uses the 40GBASE-CR4 standard with four lanes of 10 Gbit/s each aggregated through the QSFP+ interface, providing sufficient bandwidth for high-speed data center interconnects and server-to-switch connections.
What type of connectors does this cable have on both ends?
Both ends of this cable feature QSFP+ network connectors, specifically 1 x QSFP+ network connector on each end. This symmetrical design ensures consistent performance whether connecting switch-to-switch, switch-to-server, or within rack-mounted configurations, and supports hot-pluggable installation in compatible networking equipment.
How long is this twinaxial DAC cable?
This DAC cable measures 16.4 feet in length, which is approximately 5 meters. This length is ideal for within-rack connections, top-of-rack switching configurations, and short-distance server-to-switch links in data center environments where 40GbE connectivity is required over distances under 7 meters.
What does 'passive' mean for this DAC cable?
The 'passive' designation means this DAC cable transmits electrical signals without active signal regeneration or conditioning electronics. Unlike active cables that include signal amplification, passive cables like this one rely on the electrical properties of the twinaxial copper to maintain signal integrity over shorter distances, resulting in simpler installation and lower power consumption.
