I used this with my Actelis ML680DF switch. Plugged it in to the SFP port, the switched recognized it and I was able to easily pass data through it. I used this particular port for a HD PTZ camera and there were no issues. I'm sure I will be purchasing these in the future to expand the Ethernet port count on different switches.
I have bought and use this kind of device in a lot of switches, specially in Cisco switches 3750 and there haven't been any issue with them.
I totally recommend it.
Powered down the switch, pushed it in and powered the switch back up. Went into the unifi controller and verified it was working! Perfect for adding a rj-45 port to uplink to my other switch and freeing up a POE port.
