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.

These have worked with every unholy combination of Intel, Mellanox, IBM, TP-Link, Ubiquity, and Cisco hardware I have.

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

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.
