FAQs

Q: What is the primary use case for the CAB-SFP-SFP-0.5 cable?
A: This cable is designed for short-reach 10 Gigabit Ethernet connections within a single rack or between adjacent racks in data centres. It's ideal for connecting switches, routers, servers, and network interface cards in top-of-rack and high-performance computing deployments.

Q: Is this cable compatible with non-Arista equipment?
A: Yes, the CAB-SFP-SFP-0.5 is compliant with industry-standard SFP+ MSA specifications and can be used with equipment from multiple vendors that support 10G SFP+ ports, including Cisco, Juniper, Dell, HPE, and others, provided they accept third-party cables.

Q: What is the difference between passive and active DAC cables?
A: Passive DAC cables like the CAB-SFP-SFP-0.5 use no electronic components and rely solely on copper conductors, making them lower cost and consuming less power. They are suitable for short distances up to 7 metres. Active cables include signal amplification for longer reaches but consume more power.

Q: Can this cable be used at speeds lower than 10G?
A: Yes, the cable can support lower data rates including 1G SFP connections in compatible equipment, though it is optimized for 10G performance. Check your equipment specifications for multi-rate support.

Q: Does this cable require any licensing or configuration?
A: No, direct attach copper cables are passive components that require no licensing or configuration. They are plug-and-play and automatically detected by compatible SFP+ ports once inserted.
