Spoke to their customer service team who recommended me the correct configuration for our case. Once the order was placed, they made the custom cable quick and got it shipped out the next day. High quality cable that worked perfect!

I know there are some people who are hesitant to use copper products like this but, it works just fine. I put this in my FS 3900 switch to another one, and it worked flawlessly. It is SHORT since my two switches are close to each other on my rack. There is no difference on the performance of DAC solution and the fiber cable plus transceivers, and the DAC cable was priced very competitively. All in all, I am extremely happy with this purchase and will consider buying from now on as needed for any projects.
