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

Good quality, low price, functional.

Great value, work as described, functions with Meraki switches without issue. Perfect price for on hand emergency spares.

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.

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

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

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...

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 edgerouter4 and gs110tp, i bought two of those in the hope of connecting the router to the switch via sfp.Upon connection, nothing happened, no green light, nothing.I left them in their boxes thinking that i didn't do enough research to ensure compatability.As a last resort, i decided to contact 10gtek and ask for advice.I got a response within few hours stating some troubleshooting steps trying to pin down the problem.The first suggestion was to try another fiber cable which i didn't have and i had to buy it, once arrived, i connected it and the green lights came up on both the router and the switch, so far so good!Thanks a lot Freya from 10gtek for the quick response and the helpful suggestions.Soon i will buy two more to extend my network.
