DAC Question: Mellanox MCX314A-BCBT <-> Arista 7050QX-32

[TMtmTL]

Searched through the forums and can't find a definitive answer regarding a DAC for this setup. Hoping someone has first hand experience. If a gun was to my head I would buy this:

Arista Networks CAB-Q-Q-1M 40G QSFP+ DAC Cable | FS.COM

Just looking to make sure I get something that works since I need 16 of them.

Any passive DAC cables should work.
I have various IBM branded Mellanox and Broadcom cables (1-3m) and they work with the CX-3 and my Arista 7050Q-16.
