Arista 25GBASE-CR SFP Twinax Copper Cable, 3 m

Three meters gives the Arista CAB-S-S-25G-3M enough length for adjacent racks. It is a 25GBASE-CR twinax copper cable at 25GbE, terminated with SFP28 connectors at each end.

Choosing the right length avoids excess cable in the rack, so compare your layout against the cable before ordering. Copper twinax at this speed is a common choice for short server links, where a pair of optical modules would add cost without any benefit. Count the cable managers on the path, since a cable that runs through several of them needs a little more slack than the straight-line distance suggests.

The cable is a single piece, with connectors attached, and works only with SFP28 ports. It can be requested new, refurbished or used. Warranty is 1 year or 3 years on new and refurbished stock, and 90 days on used stock.
