Product Features
Technical Overview
This cable implements the 40GBASE-CR4 standard, which aggregates four 10 Gbit/s lanes to achieve a total bandwidth of 40 Gbit/s. The QSFP+ end connects to a single 40GbE port, while the four SFP+ ends distribute the signal to 10GbE ports, enabling flexible connectivity options for network aggregation or breakout configurations.
The twinaxial copper construction provides robust electrical performance with low latency, making it suitable for high-speed data transfer within racks or between adjacent equipment. The passive architecture means no signal processing or retiming occurs within the cable, relying instead on the host device's electrical interfaces for signal conditioning.
Key Product Advantages
This direct-attach cable offers several practical benefits for network administrators seeking reliable high-speed connectivity without the complexity of fiber optics. Its passive design eliminates power consumption and heat generation associated with active cables, while the twinaxial construction provides durable, flexible cabling that withstands typical data center environments.
Cost-Effective 40GbE Solution
Delivers 40 Gigabit Ethernet performance at a lower total cost than optical transceivers and fiber cables, ideal for budget-conscious deployments where short-reach copper meets technical requirements.
- No separate transceivers needed
- Lower power consumption than active cables
- Simplified inventory management
Dell Compatibility Assurance
Designed and tested for compatibility with Dell networking equipment, ensuring reliable operation in Dell-based network infrastructures without compatibility concerns.
- Tested with Dell switches and routers
- Plug-and-play with supported devices
- Reduces deployment risk
Passive Reliability
The passive design means no electronics to fail within the cable itself, increasing overall system reliability while maintaining signal integrity over the specified 5-meter distance.
- No external power required
- Lower failure rate than active cables
- Consistent performance over time
Deployment / Use Cases
This QSFP+ to SFP+ breakout cable is particularly valuable in data center environments where 40GbE uplinks need to connect to multiple 10GbE devices. Common applications include connecting top-of-rack switches with 40GbE uplinks to servers with 10GbE network interfaces, or aggregating multiple 10GbE links into a single 40GbE port for backbone connectivity.
The 5-meter length provides flexibility for within-rack or adjacent-rack connections, while the Dell compatibility makes it suitable for organizations standardized on Dell networking equipment. Network administrators can use these cables to create cost-effective 40GbE links without investing in optical transceivers for short-distance connections.
Data Center Server Connectivity
Connect 40GbE switch uplinks to servers with 10GbE network interface cards, enabling high-speed server access while maximizing port utilization on core switches.
Network Aggregation
Consolidate four 10GbE links into a single 40GbE connection for backbone or inter-switch links, simplifying cabling while increasing aggregate bandwidth.

FAQ
What is the difference between this passive DAC and an active optical cable?
This is a passive direct-attach copper cable that uses twinaxial copper conductors without any signal processing electronics. It relies on the host device's electrical interfaces for signal conditioning and has a maximum reach of 5 meters. Active optical cables contain optical transceivers and fiber, can reach longer distances, but require power and cost more. The passive DAC is ideal for short, cost-sensitive connections within racks.
Is this cable compatible with non-Dell networking equipment?
While specifically designed and tested for Dell compatibility, this 40GBASE-CR4 QSFP+ to SFP+ passive DAC may work with other vendors' equipment that supports the standard 40GBASE-CR4 protocol. However, compatibility is only guaranteed with Dell devices. Always verify compatibility with your specific switch or router model before deployment, as some vendors implement proprietary coding or electrical specifications.
What devices typically use this QSFP+ to SFP+ breakout configuration?
This cable configuration is commonly used with data center switches featuring 40GbE QSFP+ uplink ports that need to connect to servers, storage arrays, or other network devices with 10GbE SFP+ interfaces. It allows a single 40GbE port to serve four 10GbE connections, maximizing port utilization. Typical applications include top-of-rack switches connecting to servers, aggregation switches distributing bandwidth, or network appliances with mixed interface speeds.
