Review on 📡 Mini 1.25G Media Converter Kit #1 with SFP Slot & MMF SFP Module, 850-nm, 550m by Carl Mayes

It's designed to transfer 1.25GB, but actually much slower. My internet speed is 300 MB/s. I've tested it on 600 feet of single-mode duplex fiber optic cable, it's only moving at 75 MB/s. I thought it was my fiber then I went to an electronics store to buy a 9m fiber patch to test and I got the same reading. The speed was between 75 and 80 Mbit/s, exactly the same with 600 feet of fiber optic cable, so no cable but converter. it will help other buyers.
