Review on 💨 High-Performance QSFPTEK Gigabit SFP Module: 1000BASE-LX/LH 1310nm 10km DDM Single-Mode LC Mini-GBIC Transceiver for Cisco, Ubiquiti, Netgear, Mikrotik, and Open Switches by Aaron Collins

Really very easy to use. I bought it to use in ubiquiti udm pro because the WAN uplink was missing from time to time. This fitted the bill perfectly and solved the problem with configuring that second WAN port. Ubiquiti finally fixed the regular RJ45 WAN problem by updating the firmware. So I moved this module to a netgear poe switch with two sfp ports because I didn't want to use the poe port for the uplink. I have to say that it works great there too. I am planning to install another one again in Unifi as I will soon have redundant internet at home!
