10GTEK 1.25G SFP 1000Base-SX Multimode LC Fiber Transceiver Module, 850nm MMF, 550m, for Cisco GLC-SX-MMD/GLC-SX-MM/SFP-GE-S, Meraki, Fortinet, Ubiquiti UniFi, Mikrotik, Fortinet, TP-Link, Netgear

I used two of these devices to connect an Unifi USW-24-PoE switch to UDM-Pro, also using a [0.5 Meter (1.6FT) Multimode Duplex Fiber Optic Cable (62.5/125) - LC to LC - Orange, Brand: Ultra Spec Cables]. The UDM-Pro can handle 10 GB or 1 GB, but the USW-24-PoE gen. 1 only has a 1GB port. The 10 GB devices will not work in the USW, and the same device needs to be at each end of the optic cable to work. Using this setup freed up two additional RJ45 ports at my Network rack. Also, since my internet is about 920 GB download, I don't need the 10GB devices anyhow, as only internet traffic is coming to a from the UDM (UNVR-4 does Protect video, not the UDM). It is all working great with this setup, nothing special had to be done, plug and play...

Had zero issues with the adapters, it linked right up and getting 1GB on my SFP connection.Connected between Cisco Switch and Ubiquity EdgeRouter 4.Seems too good to be true for the price, but it's working awesome!!

I have ordered loads of these transceivers. And so far, I have yet to come across a device that doesn't like them. Works in brands like ASUS, QNAP, Mikrotik, Sonore and too many media converters to list. I really like these due to their reliability (using my first pair since early May of 2021 and they just work right out of the box. Not 'plug and pray' like some others I've bought!

10Getek has never let me down. They work in what ever I have plugged them into.

The product just works and it is easy to install.

Muy buenos, ampliamente compatibles con equipos Cisco y algunos switchs Sodola en que los probé.

Installed 4 modules in 802.3ad between an Engenius EWS1200-28T and an Engenius EWS1200D-10T. It was plug and play and works great with 10 Gigabit Aqua Fiber Optic Cable, LC/LC, Multimode, Duplex (#B01735WPSE).

I have used these before to electrically isolate my outdoor security cameras from my network. This time I have done the same with my DVR's network connection with perfect results.
