Arista CAB-SFP-SFP-2.5 | 10G SFP+ Direct Attach Copper Twinax Cable, 2.5m

Q: What is the maximum distance for this cable?
A: The CAB-SFP-SFP-2.5 has a fixed length of 2.5 meters (8.2 feet) and is designed for short-reach connections within a rack or between adjacent racks in data center environments.

Q: Is this cable compatible with non-Arista equipment?
A: Yes, this SFP+ DAC cable is compliant with industry-standard specifications including IEEE 802.3 and SFP+ MSA, allowing interoperability with other vendors' equipment that supports standard 10G SFP+ ports, though Arista equipment compatibility is guaranteed.

Q: What are the advantages of using DAC cables versus optical transceivers?
A: Direct attach copper cables offer significant cost savings compared to optical transceivers with fiber, consume less power, require no external power source, and provide excellent reliability for short-distance connections. They are ideal for cost-effective 10G connectivity within racks.

Q: Does this cable support Fibre Channel applications?
A: Yes, the CAB-SFP-SFP-2.5 supports 8G Fibre Channel (FC) and 10G Fibre Channel over Ethernet (FCoE) applications in addition to 10 Gigabit Ethernet, making it versatile for converged network and storage environments.

Q: Is this a passive or active cable?
A: This is a passive copper cable, meaning it contains no active electronic components. Passive DAC cables are suitable for shorter distances (typically up to 7 meters) and consume minimal power, making them ideal for high-density deployments.
