Fiberoptic Ethernet and bits on the wire

[tw99]

When someone can show the output of a DAC being affected by anything happening in the Ethernet domain, please let me know.

Until then, it's just the usual artificial, invented problems, with "solutions" that happen to be for sale for £££.

Hospitals use ethernet isolators

Arnt those transformers?

Honestly if you aren't having an issue then you are all set... I see you have some Atmos and when distributed from an AV Amp all is good, but some systems are distributing via AES67/Ravenna and these want PTPv2 (e.g. Netgear AV series but also inexpensive Mikrotik etc) and these pro-grade switches are tyically SFP+ or SFP28 based so can handle both RJ-45 copper and fiberoptic... IEEE 802.1AS are a new set of networking standards for AVB etc ...

All atmos/surround speakers are active and fed by XLR.
Only RJ45 to the TV and the AVR. (and PC )

Lots of mentions of PoE... does any of you use it in their home network? I know why it's convenient in some places, but not sure why I'd use it at home... And I am not sure why anyone would think it could pose challenges that another device with a $1 wall wart doesn't...

Because any cable laying is a PITA especially for hard-to-reach spaces, and labor costs for laying usually far exceed material costs. I know this too well as part of my job.

It's the entire reason why POE was created.

I have used PoE. I powered an outdoor ubiquiti bullet client/access point/bridge & that was nowhere near mains!
Worked well, saved a mains point. PoE has no effect on audio, as said above - another $red $herring....

Certainly, and FWIW I wired my own house with singlemode fiber from my upstairs office down to the basement ... not for audio but to centralize by NAS ON 100GbE runs. Surround/Atmos could be hardwired to your TV/blu-ray players but I keep my media on my NAS as FLAC. Distribution then by AES3 or AES67 to powered speakers. AES67 allows/would allow the speaker to get both its power and signal via Ethernet.
