They just work

Amazing Product Great Seller

Works well, with NO issues.

Worked great for my Ubiquiti US-8-150 to US-24-500 switches. Recognized immediately when using 9/125 OM2 fiber.

Fair SFP units with their own chips and firmware. Not 10 or 40 Gigabit capable, like you would want in any new system, but they’re what we have on this marketplace, and have lasted for several months reliably, unlike some other multimode units I’ve used in the past. They are easy to slide and clip into device SFP sockets/ports, and are tight fitting yet loose enough for sheathed reinforced fiber optic lines, very easy to install. Heat level is 18.3 Fahrenheit over a 75F ambient environment with no data being transmitted, or about as much as a 3 decade old ceiling fan motor on medium.If the manufacturer wants to tell me how to update their firmware, if they offer updates, please send a message.

The media could not be loaded. I have a couple UniFi 8 port PoE switches that were running out of ports, by adding these SFP to RJ45 transceivers, I essentially added additional ports to my switches for $11 per port (I put one in my 48 port switch too!) In my case I use them for the uplink / downlink between switches, where I don’t need PoE, leaving the PoE+ ports open for cameras. They’re easy to install, but do read the little booklet, there’s a clip you must open to put them in or take them out. I quickly installed this 4 pack and was back up and running, I have 1Gbps, but if you have faster SFP+ (2.5Gbps) they have transceivers for those too. Good buy in my book (or switch).

I wanted to link my poe switches and figured this was the best way to do it.So far they are working as expected.

Used these on a pair of Netgear GC110 switches spanning ~360ft between 2 buildings. Works great, stable 1gbps connection.
