FAQs

Q: What is this cable used for?
A: The CAB-SFP-SFP-0.5M is a passive direct attach copper cable designed for short-reach 10G connections between switches, routers, servers, or storage devices with SFP+ ports, typically within a single rack or between adjacent racks in a data centre.

Q: Is this cable compatible with non-Arista equipment?
A: While designed and coded for Arista switches and routers, many third-party versions are available that support multi-vendor compatibility. Always verify compatibility with your specific equipment before deployment.

Q: What is the difference between passive and active DAC cables?
A: Passive DAC cables like this one contain no active electronics and rely on the host equipment's signal strength, making them suitable for shorter distances (typically up to 7m). They consume less power and are more cost-effective than active cables or optical transceivers.

Q: What data rates does this cable support?
A: This cable supports multi-gigabit data rates from 1.25Gbps to 10.5Gbps, making it suitable for Gigabit Ethernet, 10G Ethernet, Fibre Channel, and InfiniBand applications depending on the connected equipment capabilities.

Q: Does this cable require any special licensing or configuration?
A: No, this is a passive copper cable that requires no licensing. It is plug-and-play once inserted into compatible SFP+ ports on both ends. The cable EEPROM is pre-programmed for automatic recognition by Arista equipment.
