Review on Converter SFP Transceiver 550M Ipolex by John Arrow

100m LWL laid for lightning protection, bought to connect them. Really lazy because I have sfp cells on both sides. They were working with fiber optics, which I've basically been trying to mess up for a few months. I recently took out the SFP transceivers and put them in two different brands of switches and everything works fine. I will be buying more SFP transceivers to replace so I can experiment with fiber. Basically, if you want a cheap way to test fiber optics that you can use for a long time, I think this is a good buy.
