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

Works as advertised. No issues, plug and play on the Unifi USW AGGREGATION 10G switch. The other end is a UGREEN 6 port ethernet switch. It also works fine on a UNRAID server with a 10Gtek PCI-E BIC Network Card. No complaints and speed tests are meeting expectations.

Good value for money: Many users report that these modules work as expected for 10 Gbps fiber links and deliver full 10 G speeds with proper multimode fiber (OM3/OM4, LC) up to ≈300 m. They’re often praised for being plug-and-play and compatible with a broad range of switches and NICs (Cisco, Dell, Aruba, Ubiquiti, Mikrotik, etc.), though results can vary by brand and firmware. Especially for home labs, small business networks, and DIY deployments, they’re seen as a cost-effective alternative to OEM modules. Decent reliability: Some users who have used them for a year+ have reported no failures or speed issues. Physical build quality (metal housing, low power draw) is generally considered fine for frequent use.

When the 10Gtek arrived in the usual new "green" shipping package, I felt the "box" it wasn't the usual and I had to get this thing open and see what it is. The container it comes in is genius. It took the great deal I got and hope that it works to "Holy Crap this is So Cool!" and no doubts about it's operation. Upon opening the little metal box by sliding the top, there was the dongle. I had a bit of a problem taking it out of the plastic holder. But once out if it weren't for the way the device was presented I wouldn't have been as impressed. There's nothing initially special about any of these things, so it's not the only one that's "non-descript". Although it's a great value it doesn't seem cheap. I started to look for any specific instructions that if there were any special directions that needed to be considered. I took out the plastic holder insert the dongle came in and no little folded piece of paper with type so small you need a microscope to read it. But then noticed the instructions were painted on the under side of the lid which are simple, very readable and easy to understand. It fits like a glove when I plugged it in and is completely compatible with my UniFi UDM Pro and works without needing anything special. Pop it in and that's it. The system is showing it as if it were OEM. Make sure you use a minimum of a Cat6a cable, it does matter. The Heat Level, I haven't noticed anything more than warm. Speed wise, right now I only have a 1Gbps connection but I'm getting over the spec'd 940 Download/940 Upload speeds. This coming Saturday I'm having 10Gbps installed and I trust that I'll get darn near their spec'd maximum speeds. Can't wait.

I needed a way to fully utilize the 10G RJ45 uplink provided by my ISP gateway and only had an SFP+ port with that capacity on my UDR7. This module plugged in with no issues and was up and running in a couple minutes. It’s been doing its thing in the background since with no issues. It does run a bit hot so you’ll want to let it cool down if you have to move it, but I haven’t seen it be an issue while in use.

UPDATE 11/30/2025 - Received a replacement and plugged in and worked perfectly. There were no instructions with the device, but pretty straightforward to use. Just plug it in the SFP+ and it was up and running. Great transceiver at a good price. ------------------------------------- I was excited to try the SFP+ transceiver but when I opened the box it was empty with no transceiver inside. Looks like a return that sent it back. I sent it back for a replacement. I will update my review when I receive and actual transceiver.

These worked right away, I am happy with the price, the quality and the compatibility on my Unifi switches. I didn't have to really do anything other than plug them in and run the fiber optic cable. The LC connections were stable and it firmly connected. Hard to beat the price, its definitely less expensive than buying them from the manufacturer. They fit perfectly and the temp monitoring seems to be great.

These worked exactly as expected. As others have noted, they do run hot, but in an open area the heat dissipates without any real problems. My home network now operates with the bandwidth that was my goal.

Works as advertised. Gave my Qnap Nas 10g network speed. :)

Perfecto tanto en un Switch Zyxel como en el minisforum.

Well packaged in metal tins. Works with qnap QSW-2104-2S switch and Intel pcie 520 chipset running on freebsd. Very happy. :-).

bought 2 pcs for my zyxel xs1930 sfp+ uplink and working well. will monitor how well the quality is. ordering more for other sfp+ interfaces

Regardless of which combination of PCI-e slots and settings I used, I wasn't able to get this above 3gbps even using fibre cables and transceivers. Returned it and gave up.

Full speed with UI switch, no problemo.
