Ethernet cable for Streaming

You can also make the bulk of your run using fiber for a small cost.  Two converters like these and 45-50 feet of fiber with very short CAT 8 runs at either

end.

Reading this thread with interest. Especially the post quoted above. 

My listening room adjoins the room where my ISP router (modem) sits, feeding my TP Link Archer router. My router feeds a TP Link switch feeding a lot of items such as TV, Sonos speakers, Phillips Hue Bridge, Blu-ray player TV box. So, a few noisy walk warts, and other electrical noise potential. 

I've taken a direct feed/run of 15m of shielded Cat6a from my router, in to the adjoining listening room to feed my Bluesound Node; would it be beneficial to cut out any electric/RF noise from the TV room etc, by breaking the run of Cat6a, doing as suggested above and introduce a short length of Optic cable between 2 converters, and reintroducing a short run of regular ethernet cable, probably Cat8? 

Thanks for reading

That is how I started, with a short run of fiber at the end.  Consider the CAT cables are susceptible to picking up EMI/RFI and the fiber is not.  Why not just run the whole 15M as fiber with a very short CAT cable of your choosing from the second converter to your streamer/server?  That is how I ended up - with the long run in fiber.  Consider buying a LPS for (at least) the last converter instead of using the wall wart.  Some report benefits from using LPSs on both converters and the router, which is what I have done. Also, make sure you purchase the correct fiber cable that matches the connections on whichever converters you purchase.  Good luck.

Well, I decided to install the Monoprice CAT8 50' cable. Seems to be well constructed, having Al foil shield around each of the 4 wire pairs and a braided shield around these. Quality terminations.

 If any issues arise I will go the WiFi extender route.

Thanks for all the advice. 

@mitch2 thanks very much for the advice. I went with a short run of optical fibre between a pair of TP Link converters you linked in one of your previous posts above. My Cat6a feeding in to the first converter, and a short run of Supra Cat8 terminated in Telegartner connectors. 

I suspected there was some noise coming from the Cat6a as it is plugged in to my router, which lives with the TV etc as described previously, but this new set up surpassed my expectations. 

It feels like the stream to my Bluesound Node has been given a good clean on the way in 😊, everything sounds crystal clear. In comparison, I now realise the stream I was receiving was a tad grainy. I've swapped back and forth a few times, from Cat6a direct and the converters/Optic fibre/Cat8, and it's quite a significant improvement. 

Thanks again, a great improvement, for relatively little expense👍😊

Best 14.00 dollars I ever spent.. Cat 5 to Cat 8.
