Home network Fibre optic vs Ethernet

If I was going to rewire my house, I would go with cat6/7 cable for future needs. We don’t know what bandwidth will be needed in 5 or more years. How about streaming 4K/8k for example. 
Fibre has many advantages and some hurdles. Fibre is hard for an end user to terminate, so the end user will buy premade fibre cables which are expensive or the connectors for self termination are expensive. Hardware to use fibre is expensive and I don’t know any dac that features a fibre input.

Benefits to fibre: no noise, less jitter, no/reduced latency, speed. 

@mitch2 : +1 Agreed. Keep it simple. Good listening. Jeff

Massive thanks to everyone involved on this topic. There is a lot to get through. 
 

I will be keeping things as simple and within budget. Even looking beyond any potential sonic improvements, this will be interesting experiment and build…

thanks again. 
 

For short runs Quality Ethernet cables Are around $1k x 2  sonically better then fiber optic I have tried the best fiber optic and plug in modules 

fiber loses its naturalness compared ,I am referring to a quality setup 

and a good LPS power supply to the morer-router, if you have older separate units 

get rid of them I bought a Motorola 8702 superior in every way 1 less power cord ,1 less Ethernet cable . The Linear Tube Audio 12v  up to 8 amp  at our audio get together compared up to $1200 Paul Hines units ,the Linear tube audio at $750 is by far the best best internally as well as sonically with a excellent DC cable to the router that the competition charge $150 extra , I also put in a synergistic purple fuse, and use a decent Pangea awg14 sig mk2 power cord , and a much better switch Jays audio and Alvin at Denafrips teamed up with their SW-8 Ethernet switch which has a Tumora LPS ,low noise regulators and a over controlled clock ,for around $600 an excellent value and another step for very good streaming . Everything counts in the audio chain ,being a dedicated Audiophile doesnot come cheap around $4+k just to get here the next upgrade the T+A 200 dac which is a bargain at $7200 retail price we have compared pretty much everything up to $15k, the T+A is very balanced. Myself have to save for my 🎅 🎄 Xmas present my pockets are not that deep.

+1 @mitch2 !  Except for the fact that I have not run fiber, my digital front is quite similar to yours.  My modem has WiFi disabled, M12 switch w LPS, 30 feet of Supra cat 8, Net Isolator from NA, then their Muon System.   All of these upgrades I can hear.
