Description

The Arista CAB-SFP-SFP-0.5M is a 0.5-metre passive Twinax Direct Attach Copper (DAC) cable delivering 10GBASE-CR connectivity for short-reach data centre interconnects. Designed for top-of-rack and in-rack server-to-switch cabling, this SFP+ to SFP+ cable operates at 10 Gbps with just 0.1W power consumption — making it an efficient, cost-effective alternative to optical transceivers in high-density environments. It is hot-swappable, RoHS compliant, and fully certified across all Arista platforms.

Compliant with SFP+ MSA industry standards and supported across all Arista EOS releases without minimum version requirements, this cable integrates seamlessly with Arista CloudVision for plug-and-play deployment. It also supports 8G Fibre Channel and FCoE applications alongside standard 10 Gigabit Ethernet. Order now at iptrading.com.au — trusted by Australian IT professionals.

FAQs

Q: What is the CAB-SFP-SFP-0.5M used for?
A: This 0.5-metre passive DAC cable is designed for short-reach 10 Gigabit Ethernet connections within data centre racks, such as connecting top-of-rack switches to servers or linking adjacent switches at speeds up to 10 Gbps. It is also compatible with 8G Fibre Channel and FCoE environments.

Q: Is this cable compatible with non-Arista switches?
A: The CAB-SFP-SFP-0.5M is SFP+ MSA compliant, which means it may be compatible with other vendors' SFP+ ports. However, it is officially certified for use with all Arista platforms and is fully supported under Arista EOS. Compatibility with third-party equipment should be verified before deployment.

Q: Does this DAC cable require any special software or licensing on Arista switches?
A: No. The cable is supported across all Arista EOS releases with no minimum EOS version requirement and operates as a plug-and-play device. No additional licensing is needed.

Q: What is the difference between a passive DAC cable and an active DAC cable?
A: A passive DAC cable, like this 0.5-metre Twinax, contains no active electronic components and consumes minimal power (0.1W). It is ideal for very short distances (typically up to 3 metres). Active DAC cables include signal amplification electronics for longer reach but consume more power. For sub-metre rack interconnects, passive is the preferred and most cost-effective choice.

Q: Can I purchase the Arista CAB-SFP-SFP-0.5M in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is a trusted Australian B2B IT hardware reseller supplying genuine Arista cables and transceivers to data centre operators, enterprise IT teams, and managed service providers across Australia. Order online or contact our team for volume pricing.

Q: What protocols does the CAB-SFP-SFP-0.5M support beyond 10GbE?
A: In addition to 10 Gigabit Ethernet (10GBase-CR), this cable supports 8G Fibre Channel and Fibre Channel over Ethernet (FCoE) — making it suitable for converged data centre environments where storage and network traffic share the same physical infrastructure.
