Review on 🔌 Wiitek 10GBase-T SFP+ to RJ45 Copper Modules: Compatible Transceiver for Cisco SFP-10G-T-S, Ubiquiti, D-Link, Supermicro, Netgear, Mikrotik, Unifi (Cat 6a/7, 30-Meter) by Jennifer Washington

At the time of writing this review I was a Comcast Gigabit plan user. They recently lowered the speed to 1200Mbps. Given the 20% redundancy that Comcast typically offers, that means I should theoretically be able to get around 1400Mbps with the right modem. I ended up buying a Motorola MB8611 as it has a 2.5Gb RJ45 port. Motorola MB8611 -> Cat6 patch cord -> Wiitek transceiver -> Chelsio NIC in my pfsense box. Went like clockwork. My pfsense box "sees" a 10GB connection even though there is a 2.5GB connection on the other end of the Wiitek transceiver. It's going to be hot, so you know you're in for it. Ventilate the room well if it bothers you.
