Review on 🔌 Efficient UBIQUITI U Fiber Single-Mode SFP 1G for High-Speed Networking by Doug Virden

I have installed many of these things in switches and routers from EdgeWater, Ubiquiti and Mikrotik. I haven't had a single crash. Sometimes on Mikrotik you need to enable Ethernet auto-negotiation and leave it at 1Gbps/full duplex, but they still work and they're reliable. My longest line is 1.5 km long and I transmit -5.9 dBm and receive -7.8. dBm With attenuators I've tested them down to -22dBm with no issues, so I think they can go much further.
