Product Features
Technical Overview
This DAC cable adheres to the 40GBASE-CR4 and 10GBASE-CU standards, providing a robust copper-based interconnection for 40 Gigabit Ethernet networks. The QSFP+ end features a single high-density connector that interfaces with 40 GbE ports, while the breakout end distributes the signal across four SFP+ connectors, each capable of 10 GbE throughput.
The twinaxial cable construction ensures stable signal integrity over its 2-meter span, with passive circuitry that requires no external power or management. This design simplifies deployment and reduces points of failure, offering a cost-effective alternative to active optical cables for short-distance applications.
Key Product Advantages
This cable delivers high-performance connectivity with several distinct advantages for network deployments.
High-Density Breakout
Enables a single 40 GbE port to support four 10 GbE connections, optimizing port utilization and reducing hardware costs.
- QSFP+ to 4 SFP+ configuration
- Maximizes switch port efficiency
Passive Reliability
Operates without active components, lowering power consumption and eliminating potential points of failure associated with optics or electronics.
- No external power required
- Plug-and-play installation
Arista Compatibility
Engineered to work seamlessly with Arista network devices, ensuring reliable performance in certified environments without compatibility concerns.

Deployment / Use Cases
This DAC cable is suited for various network scenarios where short-reach, high-speed interconnections are needed.
In data center top-of-rack deployments, it connects leaf switches to servers or storage arrays, aggregating 10 GbE links into a 40 GbE uplink. For network consolidation, it allows older 10 GbE equipment to interface with modern 40 GbE switches, extending infrastructure life without costly upgrades.
Data Center Interconnect
Ideal for linking switches within the same rack or adjacent racks, providing low-latency, high-bandwidth connections for clustered computing or storage networks.
Network Aggregation
Useful for aggregating multiple 10 GbE server links into a single 40 GbE switch port, simplifying cabling and improving manageability in virtualized environments.

FAQ
What is the purpose of this QSFP+ to SFP+ breakout cable?
This cable converts a single 40 Gigabit Ethernet QSFP+ port into four 10 Gigabit Ethernet SFP+ connections. It is designed for network aggregation, allowing you to connect multiple 10 GbE devices to a 40 GbE switch port, optimizing port usage and simplifying cabling in high-density environments like data centers.
Is this an active or passive direct-attach cable?
This is a passive direct-attach copper (DAC) cable. It operates without active electronics or external power, relying on the twinaxial copper construction to transmit signals over short distances. This passive design ensures plug-and-play functionality, lower power consumption, and reduced failure points compared to active cables.
What network devices is this cable compatible with?
The cable is specifically noted as Arista compatible, meaning it is engineered to work with Arista Networks switches and routers that support 40GBASE-CR4 QSFP+ and 10GBASE-CU SFP+ interfaces. It is suitable for network devices requiring short-reach, high-speed copper interconnections within Arista-based infrastructures.
What is the maximum data transfer rate supported?
This cable supports a data transfer rate of 40 Gbit/s. The QSFP+ end handles the full 40 GbE bandwidth, which is then distributed across the four SFP+ connections at 10 GbE each, maintaining high-speed performance for aggregated network traffic without bottlenecks.
