Review on 🔌 TRENDnet Intelligent SC Fiber Media Converter (20KM, 12.4Miles), 1000Base-T to 1000Base-LX/SX, Fiber to Ethernet Converter, SC Type Fiber Port, RJ-45, Lifetime Protection, TFC-1000S20, Black by Cameron Aleman

I've been using these for years but for some reason I had trouble with them recently after a power outage. As others have reported, if power is lost at one or both ends of the link, sometimes (but not always) the link will not recover afterwards. The fix is an incredible annoyance, but at least it seems to work reliably: you have to disconnect both ends of the connection, *physically plug the ethernet cables into different ports on the ethernet switch at each end*, and then turn it back on. high. I have no idea what could happen, but apparently the switch's MAC address/port mapping tables are somehow encrypted and cannot be recovered. only lights up when a full fiber optic link is established. So you might think your ethernet cable or switch port is bad if you don't get a link indicator, although it might just be a problem on the fiber side. I bought another one of these to have a spare, any other gigabit fiber paths I have configured I will be using something else.
