Product Features
Technical Overview
This DAC cable operates on the 40GBASE-CR4 and 10GBASE-CU Ethernet standards, delivering aggregate throughput of 40 Gbit/s across four 10 Gbit/s lanes. The QSFP+ end features a single male connector that interfaces with 40GbE ports, while the breakout end terminates in four SFP+ male connectors for 10GbE connectivity. The passive design eliminates active circuitry, reducing power consumption and heat generation while maintaining signal integrity over the 9.8-foot distance.
The twinaxial cable construction provides superior electromagnetic interference (EMI) resistance and stable electrical performance compared to traditional copper alternatives. This cable is engineered for hot-pluggable operation, supporting live insertion and removal in compatible network devices without system disruption.
Key Product Advantages
This cable simplifies high-density network deployments by consolidating multiple 10GbE connections into a single 40GbE port, reducing cable clutter and improving airflow in rack environments. The passive twinaxial design ensures reliable performance with lower latency and power consumption than active optical cables or transceiver-based solutions.

FAQ
What is the purpose of this QSFP+ to 4 SFP+ breakout cable?
This cable converts a single 40GbE QSFP+ port into four independent 10GbE SFP+ connections, enabling high-density network configurations. It allows network administrators to maximize port utilization on switches, reduce cable clutter in racks, and create efficient spine-leaf or server aggregation architectures without requiring multiple discrete cables or active transceivers.
What does 'passive DAC' mean for this cable?
Passive Direct Attach Copper (DAC) indicates this cable uses passive electrical signaling without active circuitry or power requirements. Unlike active optical cables or transceivers, it relies on the host device's electrical interfaces to drive signals, resulting in lower latency, reduced power consumption, and simplified deployment. The twinaxial construction ensures signal integrity over the 9.8-foot distance suitable for short-reach data center applications.
Is this cable compatible with non-Dell network equipment?
While engineered and validated for Dell compatibility, this 40GBASE-CR4 QSFP+ to 4 10GBASE-CU SFP+ passive DAC cable may work with other vendors' equipment that supports the same Ethernet standards and connector types. Compatibility depends on the specific network device's QSFP+ and SFP+ port specifications, so verifying interoperability with your equipment manufacturer is recommended before deployment.
What are the typical use cases for this breakout cable?
Common deployments include connecting 40GbE top-of-rack switches to 10GbE servers in data centers, creating spine-leaf network fabrics, aggregating multiple storage or virtualization host connections, and building high-performance computing clusters. It is particularly valuable in environments where port density, cable management, and cost-effective high-bandwidth connectivity are priorities.
