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, TP-Link and More, Pack of 2

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.

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

Got a 2-pack of SFP+ to fiber adapters so I could run a direct line up to a switch in my office from the basement where all the networking gear is. First of all, they did NOT have to go this hard on the packaging. The adapters come in a tin with custom artwork of an anime dude in a lab coat wielding a giant version of the connector that looks awesome. The printing is well made and the info on the package is clear. I actually wanna keep this tin for something now! The devices themselves work as advertised. They seem reliable, well made, and easy to use. No complaints about speed or fit. They just work. No compatibility issues connecting between a UniFi cloud gateway and an off-brand switch. All around worth it. 10Gtek is really making a name for themselves in this space with effort like this and I truly appreciate it.

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.

Used to connect a Ubiquiti Pro Max 16 switch along a 80 foot fiber run to a Ubiquiti Pro XG 8 port switch and it's run solid without generating too much heat, no signal loss, and maximum speeds. 45C at the 16 and 54C at the 8 port. Overall happy with it, but also not testing it to the full 300 meters. For my home network use, I've been happy with it. And might buy some more when I expand out the network.
