6COM 10GBase-T SFP+ Transceiver, 10G SFP+ to RJ45 Copper Module, CAT.6a/7, up to 30 Meters, compatible for Cisco SFP-10G-T-S, Ubiquiti uacc-cm-rj45-mg, D-Link, Supermicro, MikroTik S+RJ10 and More

In my Mikrotik CRS305 switch it negotiates properly at 5GbE as advertised. A solid five stars for now but time will tell if it's really up to the job. These modules (in general, not this specific one) have a habit of getting really hot to the touch and stop working sometimes. What I will say is the construction of this module does look a lot better than some of the other modules I have.

Works perfectly in my switch. Only using at 1gbps currently

Installed on my Switch supporting my WiFi6e nodes. All ports are 2.5Gbps, with a 10GBaseE GBIC connected to the router. Very good price and easy to install.

Worked perfectly on my brocade switch when others would not.

Great item and works like a charm with Asus X89X router @10g. Both 10g ports run at 10g as advertised by Asus. Easy setup on the router.
