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 ### ⭐⭐⭐⭐⭐ Would purchase again without hesitation *by S***E on October 5, 2025* This cable was used to efficiently connect two UniFi switches. It’s been in service for a month and has had zero issues. ### ⭐⭐⭐⭐⭐ Cheape and Good option! *by K***R on December 11, 2025* Works flawlessly for a Topton/CWWK firewall ### ⭐⭐⭐⭐⭐ Works between Netgear GS316P and UniFi Dream Router 7. *by W***L on March 5, 2026* My main switch in my home network is a Netgear GS316P, which has an SFP+ port on it, so I used this cable to connect it to the SFP+ port on my UniFi Dream Router 7. It's honestly unnecessary because the PC's on my network will never get 10G, but it's nice to know the bandwidth is there and maximized. Plus, the SFP+ uplink frees up an Ethernet port on the Netgear, which is almost the better reason I got the cable. ## Frequently Bought Together - 10Gtek 40G QSFP+ DAC Cable - 40GBASE-CR4 Passive Direct Attach Copper Twinax QSFP Cable for Cisco QSFP-H40G-CU50CM, Meraki MA-CBL-40G-50CM, Mikrotik, Open Switch Devices, 0.5-Meter(1.6ft) - 10Gtek 10GBase-SR SFP+ LC Transceiver, 10G 850nm Multimode SFP Module, up to 300 Meters, for Cisco SFP-10G-SR, Meraki MA-SFP-10GB-SR, Ubiquiti UniFi UF-MM-10G, Fortinet, Mikrotik and More, Pack of 10 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.at/products/67437430-40g-qsfp-dac](https://www.desertcart.at/products/67437430-40g-qsfp-dac) --- *Product available on Desertcart Austria* *Store origin: AT* *Last updated: 2026-08-16*
