ipolex 1G SFP Multimode LC Transceiver, 1000Base-SX Mini GBIC Module Compatible with Cisco GLC-SX-MMD, Meraki MA-SFP-1GB-SX, Ubiquiti UF-MM-1G, Mikrotik etc. (MMF, 850-nm, up to 550 meters) 10-Pack.

Perfect for multi gig internet.Using it to connect to isp fiber optic router. Works great and gets full 2.5gbs in udm pro

Replaced a high cost famous make and works fine in a home switch

Using these mostly with Unifi kit with no issues. If you are new to these, they do run very warm but absolutely normal.

They lasted longer that unifi branded sfp, so 5 stars for a very low budget

It works as advertises and for a month they did not even reset the port but unfortunately I have some concerns about its lifetime. It gets very hot. I mean "it gives you pain to touch" hot.

I had a single mode module just go down, these were cheap so I wasn't sure but they work fine and hadthem running longer than the last ones lasted and getting full speed.

I have used a number of these on BlackMagic SDI-Fibre miniconverters for professional applications. All have worked well. I have also used the Multimode version. Very good value.

This has saved me having to add another switch, I only needed one more ethernet port and this little bit of kit has done that for me. Works well.
