Arista AOC-Q-Q-40G-25M 25m 40GB QSFP+ Active Optical Cable

The Arista AOC-Q-Q-40G-25M is a 25-meter 40 Gigabit QSFP+ to QSFP+ active optical cable. Arista's catalog describes it as a "QSFP+ to QSFP+ 40GbE Active Optical Cable". It is built on 850nm multimode fiber with the optics sealed into each connector, and it reports digital optical monitoring data to the switch, apart from transmit optical power.

It runs between 40G QSFP+ ports, and Arista sells it in lengths from 3 to 100 meters, which makes it one of the longest-reach cable options in the range. Arista lists EOS 4.13.0 as the minimum software release.

If you need a different length, the shorter AOC-Q-Q-40G-20M 20m 40G QSFP+ active optical cable and the longer AOC-Q-Q-40G-75M 75m 40G QSFP+ active optical cable are also available. For short runs inside a rack, the passive copper CAB-Q-Q-3M 3m 40G QSFP+ direct attach copper cable is an alternative with no optics in the link.

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-Q-Q-40G-25M cable is tested, working, and covered by the NetworkTigers one-year warranty.
