Arista CAB-S-S-25G-1M 1m 25GB SFP28 Direct Attach Copper Cable

The Arista CAB-S-S-25G-1M is a 1-meter 25 Gigabit SFP28 to SFP28 direct attach copper cable. Arista's catalog describes it as a "25GBASE-CR SFP to SFP Twinax Copper Cable". It is a passive twinax copper cable. Arista notes that its 25G copper cables also run at 10G when the port is set to 10G.

It plugs into 25G SFP28 ports. Arista lists a minimum bend radius of 30mm, so leave room behind the rack for the cable to curve. Arista classes the 1-, 2-, and 3-meter lengths as CA-N cables that need no forward error correction. Arista lists EOS 4.18.0 as the minimum software release.

If you need a different length, the longer CAB-S-S-25G-2M 2m 25G SFP28 direct attach copper cable is also available. For longer runs, the AOC-S-S-25G-5M 5m 25G SFP28 active optical cable carries the same speed over fiber.

Label both ends when you install it so the run is easy to trace later, and keep the connectors capped until you are ready to plug them in.

Check that the ports at both ends of the link are set to the same speed before you connect it.

This seller refurbished CAB-S-S-25G-1M cable is tested, working, and covered by the NetworkTigers one-year warranty.
