Product Features
Technical Overview
This cable adheres to the 25GBASE-CU standard, which defines 25 Gigabit Ethernet over copper twinaxial cabling for reaches up to 3 meters. The SFP28 connectors on both ends support the full 25 Gb/s data rate, providing a direct electrical connection that reduces latency and power consumption compared to optical solutions.
The twinaxial cable construction ensures signal integrity over short distances, with robust shielding to minimize electromagnetic interference. The passive architecture means the cable does not require external power or signal conditioning, relying on the host device's SFP28 port for operation.
Key Product Advantages
This DAC cable delivers several practical benefits for network infrastructure, focusing on performance, compatibility, and deployment efficiency.
Simplified Connectivity
The integrated SFP28 connectors provide a direct plug-and-play link between devices, reducing cable clutter and installation time compared to separate transceivers and fiber patches.
- No separate transceivers needed
- Direct electrical connection
- Quick deployment
Cost and Power Efficiency
As a passive cable, it consumes no additional power and is more affordable than active optical cables, lowering total cost of ownership for short-reach links.
- Zero power draw
- Lower cost vs. active cables
- Reduced heat generation
Arista Ecosystem Ready
Designed for compatibility with Arista switches and routers, ensuring reliable performance and interoperability in Arista-based networks.
- Tested for Arista devices
- Seamless integration
- Supported topology
Deployment / Use Cases
This cable is optimized for specific networking scenarios where short-reach, high-speed connections are required between SFP28-equipped devices.
Common use cases include top-of-rack switching, where switches connect to servers or storage arrays within the same rack; spine-leaf architectures for inter-switch links in compact data centers; and router-to-switch connections in enterprise networking environments. Its 1.6 ft length makes it suitable for ultra-short runs where minimal cable management is desired.
Data Center Interconnects
Ideal for connecting switches to servers or storage within a single rack, supporting 25GbE for high-performance computing and storage networks.
Network Aggregation
Use for short links between aggregation switches or routers in enterprise or cloud infrastructure, providing low-latency, high-throughput connectivity.
