1.25/2.5/5/10G-T SFP+ to RJ45 CAT.6a Copper Transceiver, Auto-Negotiation SFP+ Ethernet Module, up to 30-Meter, for Cisco SFP-10G-T-S, Ubiquiti UniFi UF-RJ45-10G, Netgear AXM765 and More

Bought a used Intel X520-DA2 for one of my NAS devices on eBay, and until my new SFP+ switch comes I threw this RJ45 transceiver in. It was instantly detected by Synology and rated at 10Gbit using a CAT7 cable directly between my Mac Mini (with 10GbE) and the Synology. Once the switch comes, Ill move this transceiver into the switch and update this review if theres any compatibility between this 10GTek transceiver and the QNap SFP+ 10Gbit switch. Build constructions seems to be good quality, and a nice snug fit for the RJ45 connection. Inexpensive and easy to install. Cute packaging.

As soon as I plugged this into my switch, it became very hot. Hot enough to burn skin. And Im not exaggerating. And I can handle hot items with my hands. Too late to return these, so please dont waste your money on them.

I have Adtran switches with 10g sfp+ uplink ports. I was able to manually set the speed to 10gbps and these transceivers work great.

With UF-RJ45-10G you can use from 1GB to 10GB, this is just a expensive, but cheap copy that only allows 10GB.

No problems. Inexpensive replacement for coded SFP+ transceivers. Buying 10Gtech now whenever possible.

Plugged into a UniFi 10G switch, no issues and not too hot, perfect.

Performs as needed.

Works great. And when I plugged in a 1ge, it stepped it down so this unit will be very versatile

Works as ezpected, make sure you get a cat 6 or cat 7 cable with it as cat5 does not support 10 gig.

I upgraded to Spectrums Gig speed and bought my own Arris SF33 cable modem which has the 1Gbit and 2.5Gbit port. Before I got this SFP to connect to the Ubiquity Dream Machine Pro, I was getting around 800Mbit/s down. Afterwards I got around 1100Mbit/s. It was plug and play with the Dream Machine Pro into the WAN2 SFP+ port. I also purchased a new CAT6 cable to make sure I had a good quality cable. The Dream Machine Pro failed over to the SFP+ port once I disconnected WAN1 and it was up and running.
