Works well, with NO issues.

Amazing Product Great Seller

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.

They just work

Works as intended. Great price for the two. I'm glad to hear that the product works as advertised for Unifi and that you found the price to be great! It's always nice to find products that not only meet your expectations but also come at a reasonable price.

5 stars. This item is for single mode fiber connections. It works flawlessly. 2 modules were purchased and just seem to be non functional but the other is working. I will be buying more. Over 50 devices are controlled by this itemInsert sfp module, connect power to switch, then insert fiber cable. That’s it
