Question 1

Does this cable work with Dell switches? Specifically, a X1052?

Accepted Answer

This cable is Cisco compatible, so it will not work the Dell X1052 switch. For Dell X1052, we would recommend  that you purchase this Dell compatible DAC cable, please visit by https://www.amazon.com/dp/B088FNB7MR?ref=myi_title_dp

Question 2

Anyone know if these are compatible with the unifi 48-port switches (with sfp+ ports)?

Accepted Answer

Yes. I'm using several of the 5 meter cables to route through the CMA on each of my servers to a couple Unifi 16-Port Aggregation switches. I've also used them on my 48 port 750w switches' SFP+ ports before. It's a different model variation, however I'm still pretty certain it will work for yours. Also, I'd like to add, I'm using a bunch of different SFP+ cables for my Unifi equipment. I'm yet to run into an SFP+ compatibility issue across the different variations I've used. Including cables made for Cisco, Mellanox, Intel and brands from 10Gtek, Cable Matters, Wiitek, ipolex, QSFPTEK, to Ubiquiti's own SFP+ transceivers/DAC's.
TL;DR, honestly, Ubiquiti SFP+ ports seem to be compatible with just about every cable on the market. If it fits, it should work. Also, if it for some reason doesn't, you should be able to return the cable and get a refund.

Question 4

Can I connect two switch’s with a sfp and sfp+ port together with this?

Accepted Answer

10Gtek states that the 10G SFP+ is not backward compatible to SFP. 
SFP+ has a 10G spec and an SFP has a 1G spec and is incompatible. The main difference between SFP and SFP+ is the data rate. And due to different data rate, the applications and transmission distance is also different.
