Works great in my Ubiquity switch, connected to an old 1000Base-SX transceiver.

### ⭐⭐⭐⭐⭐ They just work.
*by M***Y on January 2, 2026*

I used these to electrically isolate the ethernet cat6 line going outside in case of a lightening strike. Instead of a ethernet surge suppressor, I installed a short 3 ft length of fiber optic cable. They worked perfectly and we can't even tell they're in the line.
