Sonore Rendu or similar

Have you looked at your Verizon FIOS router? It's copper (ethernet). Not fiber. Yes, there is fiber coming to your home, but that connects to your ONT (optical network terminal). Then Ethernet (copper) from the ONT to the Router. In other words, Ethernet (copper) into and out of your actual Verizon FIOS router. Take a look at your Verizon router: do you see any fiber in and out of it?

Telling me a lot I don't know about a topic I never thought about. Thank you.

@nglazer : I am not sure if your response was genuine "thank you" or not. Apologies for not understanding the meaning of your reply.

I have had Verizon FIOS for years now (residential FIOS, here in US), and have owned a range of their routers, including the most recent. And two of their ONTs. Unless there is a deployment somewhere that I am not familiar with, there is always an ONT and a Router combo with Verizon FIOS, same I explained in my first reply.

Easiest way to get a OpticalRendu hooked up is to get a Ethernet switch with Fibre output. The link below has such a device. Infact, that page has all the compatible pieces to get fibre into you USB DAC.

4-PORT GIGABIT SWITCH WITH FIBER PORT

Then get an OpticalRendu and take the fibre cable from the above switch to the OpticalRendu. Then take a USB cable and hook up to your DAC.

If you stereo system is far from the FIOS router and you do not have Ethernet into your room with the audio system, then there is an easy way to resolve this. In this situation, I use a PowerLine adapter to send the music bits via the copper electrical wiring of my house. It does not matter about noise BEFORE the fibre cable.

I have 3 of these OpticalRendu’s. Send me a DM if you want more help on setting this up.
