Description

The Arista CAB-SFP-SFP-1M is a 10GBASE-CR passive Direct Attach Copper (DAC) cable delivering 10 Gbps connectivity between SFP+ ports at a fraction of the cost of optical transceivers. Designed for data centre rack and adjacent-rack deployments, this 1-metre twin-ax cable eliminates active electronics for ultra-low latency and minimal power draw under 0.5W. It integrates natively with Arista EOS and CloudVision for true plug-and-play operation with no optic qualification cycles required.

Compliant with IEEE 802.3 and SFP+ MSA standards (SFF-8431/SFF-8432), the CAB-SFP-SFP-1M supports 10G Ethernet, 8G Fibre Channel, and 10G FCoE applications. Its hot-pluggable SFP+ form factor on both ends ensures straightforward deployment across Arista switches and compatible third-party infrastructure. RoHS compliant and fully backed by Arista's hardware warranty and support services. Order direct from iptrading.com.au — Australian-owned and operated since 2001.

FAQs

Q: What is the CAB-SFP-SFP-1M used for?
A: The CAB-SFP-SFP-1M is a 1-metre 10G passive DAC cable used to directly connect two SFP+ ports within the same rack or between adjacent racks in a data centre. It is ideal for server-to-switch and switch-to-switch connections where a low-cost, low-latency 10G interconnect is required.

Q: Is this cable compatible with non-Arista switches?
A: The CAB-SFP-SFP-1M conforms to IEEE 802.3 and SFP+ MSA standards (SFF-8431/SFF-8432), making it broadly compatible with SFP+ ports on many vendor platforms. However, native plug-and-play operation with full EOS/CloudVision integration is guaranteed on Arista switches. Compatibility with third-party equipment should be verified against that vendor's interop list.

Q: What is the difference between a DAC cable and a fibre transceiver?
A: A Direct Attach Copper (DAC) cable like the CAB-SFP-SFP-1M uses a passive copper twin-ax assembly with integrated SFP+ connectors, eliminating the need for separate optical transceivers and fibre patch leads. DAC cables are more cost-effective and consume less power (under 0.5W) for short-reach connections, whereas optical transceivers support longer distances using fibre.

Q: Does this cable require any drivers or licensing to operate with Arista EOS?
A: No. The CAB-SFP-SFP-1M is a fully plug-and-play passive cable that requires no additional drivers, firmware, or software licences. It is natively recognised by Arista EOS and CloudVision upon insertion.

Q: What protocols does the CAB-SFP-SFP-1M support beyond 10G Ethernet?
A: In addition to 10G Ethernet (10.3125 Gbps), the cable supports 8G Fibre Channel and 10G FCoE (Fibre Channel over Ethernet), making it suitable for converged storage and data networking environments.

Q: Can I purchase the Arista CAB-SFP-SFP-1M in Australia from IP Trading?
A: Yes. IP Trading (iptrading.com.au) is an Australian-owned and operated B2B IT hardware reseller that has been supplying networking and data centre infrastructure since 2001. You can order the CAB-SFP-SFP-1M directly through the website for fast fulfilment within Australia.
