[2 Pack] Gigabit Ethernet Media Converter with a 1Gb SFP LX LC Singlemode Module, 10/100/1000M RJ45 to 1000Base-LX, up to 20km, with a British Power Supply

I ordered 4 of these devices as I needed 2 fiber runs joining in the middle with a switch. I was trying to address a bandwidth issue with my existing powerline adapters trying to play Blueray movies from my NAS. All my issues were resolved, and from the furthest point, I am getting less than 0.5ms response to the router. Very much plug and play, highly recommended!

Got this to run fibre from my home office to the front room so the smart TV didn't keep buffering over wifi, so easy to use just plug and play with one at each of the fibre cable and all my buffering problems have gone.

Initially I couldn't get this to work when connected to my TP-link T2600G switch and LC multimode cable and Gtek module. The support I received was excellent and I managed to get full speed from the device. The network switch setting was changed to Auto Duplex.

Works well and much cheaper than other branded stuff does the job just as well.
