Arista AOC-D-D-400G-10M 10m 400GB QSFP-DD Active Optical Cable

The Arista AOC-D-D-400G-10M is a 10-meter 400 Gigabit QSFP-DD to QSFP-DD active optical cable. Arista's catalog describes it as a "400GbE QSFP-DD to QSFP-DD Active Optical Cable". It runs over 850nm multimode fiber with the optics sealed into each connector, and Arista rates its maximum power at 12W.

Arista describes these cables as commonly used for leaf to spine links. QSFP-DD ports need QSFP-DD cables, so check that both ends of your link are QSFP-DD and not OSFP. Arista sells it in lengths from 1 to 30 meters. Arista lists EOS 4.23.0 as the minimum software release.

If you need a different length, the shorter AOC-D-D-400G-1M 1m 400G QSFP-DD active optical cable is also available. For short runs inside a rack, the passive copper CAB-D-D-400G-1M 1m 400G QSFP-DD direct attach copper cable is an alternative with no optics in the link. A new AOC-D-D-400G-10M 10m 400G QSFP-DD active optical cable is also available.

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 AOC-D-D-400G-10M cable is tested, working, and covered by the NetworkTigers one-year warranty.
