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 didnt 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 didnt 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.

Weve been using these products for a while now, and each time I am pleased with the experience. No hassle, and much cheaper than the original GBICS. We will continue to use these products and would recommend them to everyone

You just like when you buy something and it works. Yep it does. Only been using it a few weeks but no errors or issues so far.

Work well

Device worked perfect with no issues.

I have ordered loads of these transceivers. And so far, I have yet to come across a device that doesnt 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 Ive bought!

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 dont 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...

This is not compatible with the Meraki MS210, although it says it is it will not work.

Bought them for our WiFi network, and it worked as intended. Didnt have any issues since then.

Its compatible with UNVR, works perfectly as expected!
