I was looking at the above for my home LAN as I transfer a lot of large files around, one of my system has an Aquantia AQN-107 built into the board and the other as an PCIe card, two other systems I have run Mellanox ConnectX2 SFP’s.

What I would like to know it what is the state of RJ45 to SFP converters at the moment which are compatible with the MicroTik switch, who should I get them from and will I strike any issues?

Thanks in advance.
