Ethet net to fiber optic to feed your streamer

I think many, many members here have one version or another of what you are asking about.  I have not tried the Sonore devices, but many on here have and have written about them.   I am very happy with the results of interposing 2 very basic FMC (StarTech via Amazon  https://www.amazon.com/StarTech-com-Gigabit-Ethernet-Fiber-Converter/dp/B011KH1O1U) with seemingly highly regarded Finsair SFP modules

https://www.amazon.com/Finisar-FTLF8519P3BNL-1000BASE-SX-Connector-Transceiver/dp/B00AM2ECU0

and Corning multimode fiber optic cable. (Make sure your fiber and SFP match — all either single mode or multi-mode .)

and then just get the shortest Ethernet cable you can manage to connect the FMC to your streamer. Lots of advice on here about whether you will benefit from a “fancy” Ethernet cable of just any well made and tested cable like this one https://www.amazon.com/Monoprice-Cat6A-Flexible-Patch-Cable/dp/B0CKYL17K1.

I have not tried a fancier one, but i am toying with the idea of testing out the ones made by Veritas Cables.

(and there are varied views on whether your Ethernet cable should be shielded or whether it shouldn’t be.)

i moved my audio off the WiFi and have it hardwired (ISP is Quantum Fiber, Now part of ATT) via a really nice Ubiquiti Router (with Ethernet RJ45 and SFP slots) and separate Ubiquity  switch with 1 SFP slot and a bunch of RJ45s that i don’t use), but it sounds like you are happy with the WiFi and just want to get some fiber optic isolation. The above will handle that for you, but there are many other “audiophile” devices that will also accomplish this for you; whether the resultant sound quality is better I can’t tell you.\

quite a few threads on here an elsewhere discuss various options and products; see e.g., WBF — FMCs and more

good luck!

high quality built units, often for hifi applications -- like ether regens, sonore optical units, using linear power supplies and better fmc modules like those by finisar all make a meaningful sonic difference in my experience

Thanks for the feedback!

My home is made motly of three foot thick walls of cement.  Routing cable is impractical and wifi gets very sketchy by all the rebar.  I think I’ll try the ethernet media converter first and if it works well move up to the 
Sonore. 

I’m using the Ultrarendu by Sonore and it is fantastic.

I can recommend the LHY FMC. Reasonably priced and does a great job. You can get excellent Fiber optic cable and SFP modules from Finisar. They are industry standard and great pricing. I run my setup into a hifi rose rs130 it has fibre module capabilities. Very clean. All told the Ethernet cable, Fibre cable the 2 Sfp modules and LHY FMC was around 600 bucks

Cheap way to give it a go

I have exactly your mesh system but my audio connections are hardwired to my base router unit.  I do also have a secondary system with the streamer hardwired to one of the router mesh satellites.

Small Green Computer (link) can economically set you up for fiber isolation, starting with their switch that has a fiber output and then, at your streamer/dAC end, their opticalModule deluxe with their 7V linear power supply.  If you wish, you can add a 5V LPS to the switch.  I use all of those and have had very good luck with SGC for my digital audio needs.
