Arista 10GBASE-CR SFP+ Twinax Copper Cable, 3 m

With 3 m of copper, the Arista CAB-SFP-SFP-3M handles 10GbE links between neighboring racks. It is a 10GBASE-CR twinax cable, SFP+ at both ends.

The cable body is copper, so it works as a direct attach link with no separate transceivers. That keeps the part count low on the many 10G ports still found in server rooms, and it makes replacement quick when a cable needs swapping. Allow for strain relief at both ends.

Pick this length when a shorter cable would be too tight, and measure the path along the cable managers. Both devices need SFP+ ports. The cable is offered in all three conditions. New and refurbished units list 1 year or 3 years of warranty, and used units list 90 days.
