QNAP Thunderbolt 3 to 10GbE SFP+ Adapter, Bus Powered, 1.08 x 2.20 x 4.41 in

I'm using this to connect a Razer Blade 2019 Advanced laptop to my 10GbE network via the Thunderbolt port and it works perfectly. I've had no problems maxing out the 10GbE network connection using a 10Gtek 10Gbase-SR SFP+ transceiver in this QNAP QNA-T310G1S adapter and connecting it to a Mikrotik CRS309 10GbE switch.The packaging and product are really well made and screams quality. The QNAP QNA-T310G1S adapter is quite large compared to an SFP+ module and it also has some weight to it too.I downloaded the Marvell AQtion AQC107 drivers, which are required for the adapter, before installing the device and I had no problems getting it to work.It does run quite warm (but not hot) and I suspect the aluminium chassis is used as a heat sink. I'm not sure on battery drain on a laptop because I only use this adapter when the laptop is connected to the mains.There's not may 10GbE options for laptops at the moment but based on my experience I highly recommend this one.Pros:- Full 10GbE speeds over Thunderbolt- Compatible with 3rd party SFP+ transceivers (I'm using 10GTek)- Decent build quality and packaging- Easy installationCons:- Does run quite warm (but not hot)

I've been using this for nearly a year now with a 2018 MBP and macOS Mojave and Catalina. Works reliably out of the box (no extra drivers required) and pushes 10G with minimal fuss - using a fs.com 10GBASE-SR SFP+ and OM3 multimode fibre to a 10G switch.

For 16.04 or 18.04, the device needs to be authorised. The divers are already in the kernel. You can do this through GNOME or the command line:$sudo apt-get install -y bolt$boltctl listCopy the UUID to the copy buffer.$sudo boltctl enroll <UUID>Where <UUID> is the number obtained from the "boltctl list" command.

Bought April 23 - stopped working Jan 24 - not impressed

Plug it into my homeland, has been running non stop for the last weeks. And it actually delivers the 10gb/s, I tested ;)
