Product Features
Technical Overview
This DAC cable operates on the 40GBASE-CR4 standard, which utilizes four lanes of 10 Gb/s to achieve an aggregate bandwidth of 40 Gb/s. The twinaxial construction provides robust electrical performance with low latency, making it suitable for high-throughput networking where fiber optic solutions may be unnecessary or cost-prohibitive for short distances.
The QSFP+ connectors are hot-pluggable, allowing for installation and removal without powering down connected equipment. This feature supports flexible network reconfiguration and maintenance with minimal disruption. The cable's passive nature means it contains no active electronics, relying instead on the electrical signaling capabilities of the connected devices.
Key Product Advantages
This cable offers several distinct advantages for network administrators seeking reliable, high-performance connectivity solutions. Its compatibility with Palo Alto Networks devices ensures optimized performance within those ecosystems, while the standardized QSFP+ interface maintains broad interoperability with other 40GbE equipment.
Cost-Effective High-Speed Connectivity
Compared to active optical cables or separate transceivers with fiber patches, this passive DAC provides a more economical solution for short-reach 40GbE connections without sacrificing performance.
- Lower total cost of ownership
- No separate power requirements
- Reduced component count
Simplified Deployment and Management
The plug-and-play design eliminates complex configuration, while the durable twinaxial construction resists electromagnetic interference in dense network environments.
- Hot-pluggable installation
- No external management interfaces
- Robust physical design
Deployment / Use Cases
This cable is ideally suited for connecting 40GbE ports between switches, routers, servers, or storage arrays within the same rack or adjacent racks. Common deployment scenarios include spine-leaf architectures in data centers, high-performance computing clusters, and storage area networks where low-latency, high-bandwidth connections are critical.
The 1-meter length makes it particularly useful for top-of-rack switching configurations, where switches connect to servers in the same enclosure. Network administrators can use these cables to create redundant links, upgrade existing 10GbE infrastructure to 40GbE, or expand network capacity without replacing entire systems.
Data Center Interconnects
Connect leaf switches to spine switches or link servers to top-of-rack switches within the same rack for optimized data center fabric performance.
Network Infrastructure Upgrades
Migrate from 10GbE to 40GbE connectivity between existing compatible devices without requiring complete infrastructure overhaul.

FAQ
What is the maximum data transfer rate of this DAC cable?
This cable supports data transfer rates up to 40 Gbit/s using the 40GBASE-CR4 standard. It achieves this bandwidth through four lanes operating at 10 Gb/s each, providing sufficient throughput for high-performance networking applications including data center interconnects, server-to-switch connections, and storage networking.
What type of connectors does this cable have?
Both ends of the cable feature QSFP+ (Quad Small Form-factor Pluggable Plus) male connectors. These connectors are specifically designed for 40GbE networking and provide a secure, hot-pluggable interface that allows for installation or removal without powering down connected equipment. The male connectors mate directly with QSFP+ ports on compatible network devices.
How long is this DAC cable?
The cable measures 3.3 feet, which is equivalent to 1 meter. This length is ideal for connecting devices within the same rack or between adjacent racks in data center environments. The specific distance makes it suitable for top-of-rack switching configurations where minimal cable length reduces signal attenuation and physical clutter.
What does 'passive' mean for this DAC cable?
A passive DAC cable contains no active electronics or signal conditioning components. It relies entirely on the electrical signaling capabilities of the connected devices to transmit data. This design simplifies the cable construction, reduces power consumption, and typically results in lower cost compared to active cables while maintaining performance for short-distance applications.
