Bought these cables for upgrading our data center to 400G. Initially, we were worried about whether these cables would work on our Arista switches. They even did a compatibility test on these cables and provided a report for us. These DACs worked and fitted perfectly on our devices. Very stable connection. Five stars!

Our new data center planned to upgrade to 400G. For our in-rack links, FS guys recommended the 400G to 2x 200G QSFP56 DAC cables. I did a test when I received them, the TX and RX powers were in spec. And the transmission was stable.

We are interested in the 400G breakout cables, but not sure if they can work with our Arista devices. The AM quickly replied and asked about our devices’ model, and ensured us the cable could work with my devices. Yeah, they did. My devices’ LED light turned on when I plugged the cables in them.
