BlueLAN CAB-SFP-SFP-0.5M Compatible Arista 10GBASE-CR Passive SFP+ to SFP+ Direct Attach Copper Cable, 0.5m

The BlueLAN CAB-SFP-SFP-0.5M is a high-performance passive direct attach copper (DAC) cable designed for 10 Gigabit Ethernet connectivity. It is fully compatible with Arista Networks CAB-SFP-SFP-0.5M and provides a cost-effective, low-power solution for short-range interconnects in data centers, storage area networks (SANs), and high-performance computing (HPC) environments.

Advantages

This passive twinax cable offers reliable 10GbE performance with minimal power consumption (<0.1W) and zero latency. Its SFP+ form factor ensures hot-swappable installation and easy cable management. The 0.5-meter length is ideal for rack-to-rack or intra-rack connections, reducing clutter and improving airflow.

Suitable for

• Data center top-of-rack (ToR) to server connections
• Storage area network (SAN) links
• High-performance computing clusters
• Network switch to switch or switch to NIC interconnects
