Product Features
Technical Overview
This cable adheres to the 40GBASE-CR4 standard, supporting a data transfer rate of 40 Gbit/s across its twinaxial conductors. The passive design means it operates without active electronics, relying on the host device's signal conditioning for optimal performance over its 3.3-foot length.
The QSFP+ connectors are hot-pluggable and provide a secure, high-density interface that supports the full 40 Gbit/s bandwidth. This cable is ideal for interconnecting switches within the same rack or adjacent racks where fiber optic solutions would be unnecessarily complex or costly.
Key Product Advantages
This DAC cable simplifies 40GbE deployments by integrating the transceiver function directly into the cable assembly, reducing component count and potential points of failure. Its passive construction ensures lower power consumption and heat generation compared to active optical cables, while still delivering the full 40 Gbit/s performance required for modern data center interconnects.
Dell Compatibility
Specifically engineered for compatibility with Dell networking equipment, ensuring reliable operation in Dell-based infrastructure environments without requiring additional configuration or compatibility testing.
- Verified for Dell switches and routers
- Plug-and-play installation
- No additional drivers required
Cost-Effective 40GbE Solution
Eliminates the need for separate optical transceivers and fiber patch cables, providing a complete 40 Gbit/s connectivity solution at a lower total cost of ownership for short-reach applications.
- No separate transceivers needed
- Lower power consumption than AOC
- Reduced cable management complexity
Deployment / Use Cases
This cable is specifically designed for data center and enterprise networking environments where high-speed, short-reach connections are required between networking equipment. Its 3.3-foot length makes it ideal for top-of-rack switch configurations, connecting switches within the same rack, or linking adjacent racks in high-density deployments.
Common applications include connecting Dell switches in spine-leaf architectures, establishing 40GbE uplinks between access and aggregation layers, and creating high-speed interconnects for storage area networks or server clusters. The passive twinaxial design provides reliable performance for these mission-critical connections while maintaining signal integrity across the entire cable length.

FAQ
What is the maximum distance this DAC cable supports?
This 40GBASE-CR4 QSFP+ Passive DAC Cable is designed for short-reach applications up to 3.3 feet (1 meter). Passive DAC cables are typically used for connections within the same rack or between adjacent racks in data center environments, where longer distances would require active optical cables or fiber optic solutions with separate transceivers.
Is this cable compatible with non-Dell networking equipment?
While specifically engineered and verified for Dell compatibility, this QSFP+ DAC cable uses standard 40GBASE-CR4 signaling and should work with other vendors' equipment that supports the 40GBASE-CR4 standard. However, for guaranteed performance and compatibility, it's recommended to use it primarily with Dell routers and switches as indicated in the product specifications.
What does 'passive' mean for a DAC cable?
A passive DAC cable contains no active electronics or signal conditioning components within the cable assembly. It relies on the host devices (switches or routers) to provide signal conditioning and equalization. This results in lower power consumption, reduced heat generation, and typically lower cost compared to active DAC or AOC cables, while still providing reliable 40 Gbit/s performance over short distances like the 3.3-foot length of this cable.
Can this cable be used for 10GbE connections?
No, this is specifically a 40GBASE-CR4 cable designed for 40 Gbit/s connections. While some QSFP+ ports support breakout to 4x10GbE, this would require specific switch configuration and compatible breakout cables. This particular cable is optimized for native 40 Gbit/s operation between compatible QSFP+ ports on routers and switches.
