Review: Reliable, Fantastic Value - With my entire network being Ubiquiti, like many others I was hesitant to purchase an off-brand device. I need Four of these, but purchased one just to see how things went. Then I ran into a problem. Plugged it into my living room switch, then nothing happened. Lost Heartbeat on the switch. Rolled back the changes then went into the controller to find my SFP ports were disabled. (Duh!) I enabled the port, then waited for the switch to detect the new SFP before moving my uplink cable. Switch recognized the device, vendor name, serial and Part Numbers. Then i moved my uplink to this port and presto! I can't speak on the 10/100 devices, as this is going back to my primary Unifi Switch which is all Gigibit. But at least I freed up a PoE port for future use. Now I will purchase three more to complete the wiring. For those wondering what is sitting next to the switch: That is an "AC Infinity MULTIFAN S2" blower style fan. These switches are passively cooled. Currently the Fan is on Medium speed, but at MAX, it dropped the Switch Temps from 150f down to 98f. 52 degree drop from a super quiet $15 USB powered fan. === UPDATE (1/27/2021) === 6 month update: The original in my living room switch went bad after a power outage. Nothing else was affected. Then one on my main switch went bad a few months later, even though it was plugged up to battery backup. It was past 30 days so I couldn't return that one. Right now I am running 3 of these and its going okay so far. Hopefully they last a while longer than a few months each. Otherwise, I'm happy with them. === UPDATE (4/30/2024) === It has been a few years now, and no issues at all. Changing rating to 5 stars!
Review: Works well in my Cisco 52-port PoE switch. - Fit in my uplink port and provided ann extra gigabit Ethernet connection.

### ⭐⭐⭐⭐⭐ Cheap and functional gigabit SFP module!
*by D***E on June 4, 2024*

I'm using this in some older Ubiquiti gear that's not SFP+ and only supports SFP (until I swap it out later this year when I do another round of home network upgrades). Works absolutely fine to interconnect some SFP gear with short cables. Zero complaints.
