Specifically, a X1052?** A: 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 If any questions, please contact us at the following link and we'll work offer you the best solution, https://www.amazon.com/hz/help/contact/AE2OZG2NN3099?marketplaceID=ATVPDKIKX0DER&ref_=v_sp_contact_seller&sellerID=AE2OZG2NN3099&_encoding=UTF8& **Q: Anyone know if these are compatible with the unifi 48-port switches (with sfp+ ports)?** A: 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. **Q: Does this work with Fortinet Fortigate's?** A: In our experience, Fortinet Fortigate's doesn't need special coding. We suggest that you can purchase a sample for testing first. If it doesn't work, we will provide you with 30 Days Free-returned. If any questions, please contact us at the following link and we'll work offer you the best solution, https://www.amazon.com/hz/help/contact/AE2OZG2NN3099?marketplaceID=ATVPDKIKX0DER&ref_=v_sp_contact_seller&sellerID=AE2OZG2NN3099&_encoding=UTF8& **Q: Can I connect two switch’s with a sfp and sfp+ port together with this?** A: 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. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Works good so far! *by T***L on February 14, 2026* Cable works as intended , happy with my purchase ### ⭐⭐⭐⭐⭐ Great alternative to Meraki qsfp cable *by C***L on July 19, 2021* I've used 10g tek stuff for a lot of installs.
