What for? Ethernet is what you ultimately need, because that is what devices such as PCs and WiFi access points use. I experimented with SFP for a while, but ultimately concluded that it isn't worth the effort to add SFP cards to PCs now that that low-power 10G Ethernet chips like the RTL8127 are available. High-end motherboards already have 10G Ethernet and soon lower-end models will too. 2.5G is practically standard already.

We are looking to the future. If you're putting stuff in the walls, then you should try to target something that will be adequate both today, and in 10 years from now.

Increasingly, prosumer stuff is including an SFP port. High end PCs will be shipping it in the near future, as well. And, while low-power chips are coming out, the simple fact is that physics are getting in the way.

I do think that the average home won't need more than 2.5gbps, pretty much indefinitely (an 8k video at "bluray quality" is about at most 5% of that bandwidth). But if you have any desire of going past 10gbps, Ethernet is not going to cut it.

And yes, before you ask, there is a 25gbase-t standard. Maximum distance: 30m (100ft). 100ft from panel to panel in a house? Oof.

Ever ran a single mode bidi fibre in a conduit? Push a wire puller, cleave and terminate ends, done. Zero effort unlike pulling a jacketed CAT7 cable, zero worries from electrical interference too, future proofing up to 40GBps. I ran double strands in my house so in case one breaks, there's another.

The floors where native fibre is not needed have a cheap ethernet media converter from fs.com, everything else (3 floor switches) are interconnected with 10Gbps SFP+ modules and 2.5G ethernet for the hosts.

All done thanks to the great https://michael.stapelberg.ch/posts/2020-08-09-fiber-link-ho...

(if you are reading this, I owe you several beers)

		The issue with this setup is that you need an extra switch with an SFP+ uplink or media converter in each room or place where Ethernet will be used. And then you still need Ethernet cables anyway for the end devices. I can't justify this complexity for 40Gbps when I can now get 10Gbps inexpensively and conveniently.

		If your walls are ripped open, then sure run some OS2 everywhere, but Cat 6A gets you 10GbE at 100m, but even 'only' Cat 5e or (plain) 6 gets you that speed up to 55m (per 802.3an): * https://en.wikipedia.org/wiki/10_Gigabit_Ethernet#10GBASE-T * https://en.wikipedia.org/wiki/Ethernet_over_twisted_pair#Var... Why the need for faffing about with media convertors, at least with-in your domicile? (Fibre outside / to the garage certainly makes sense.)

My APs are fiber now.
