To calibrate the discussion, you can get 10GB/s Wifi 7 these days spending less than $200 on a router. No need to drill a single hole in your house/apartment. Ethernet is dead for home usage. I wish companies gave a damn, but no, for the past 25 years we are stuck at 1GB/s. Only recently some laptops and motherboards started shipping with 2.5GB/s ethernet options.

You aren’t getting consistent 10gb out of wifi unless you’re sitting 2ft from the router and have nothing else on the network.

You couldn’t pay me to rip out my fiber and run strictly on wifi.

The correct solution to future proof has and probably always will be running some single mode fiber runs. The same cable would have taken you from 10mbit to 400gbit+.

The wireless standards you are using are ethernet my friend, ethernet is very alive :) and then there is backhaul, POE (30, 60, 90)

10gbps in wifi7 is great in theory but client hardware is normally 2 spacial streams, channel widths of 320 are impractical and cause me CCI even at home. Then a load of my stuff still uses 2.4. OT is a bit like that and isn't going to change. I have to share air time with my family other devicew, there are sometimes hidden nodes, DFS from the local airport.

500Mbps is more realistic.

If you want a 10GBASE-T SFP+ module that doesn't run hot, look for one with 802.3bz support. Any module that supports 2.5G and 5G speeds has newer silicon which runs cooler.

There is an old but still good list of transceivers with this feature here: https://www.servethehome.com/sfp-to-10gbase-t-adapter-module...

I feel like we have moved into the era now where if you were putting cabling in the walls for networking you should be choosing fibre now. Not necessarily because we are definitely at the stage where the home needs it, but because the off ramp is clearly happening for ethernet at 10gbit/s and its really high consumption and heat. Switching to fibre after 2.5gbit/s seems like the thing to do now and plenty of us now h…

I did just that relatively recently in a house we bought. OS2 single mode duplex throughout the house, all converging to a trunk which is available in three locations for equipment. It's basically future proof, but also has its own well, things. You can't really plug into a duplex (I wish though), you have to put a small switch to it with SFP+ or 28 or whatever the speed you want. Higher speed switches are also a tad…

Why not multi-mode? The transceivers are a lot cheaper, especially for 100G and above.

So tell me... how much did you spend? Is fiber doable without insane money.

I recently pulled OS2 fibre throughout my aparment and it was surprisingly inexpensive.

Four-fibre cable was about US$ 1.5/m (here in Switzerland, I am sure cheaper elsewhere).

I picked ONTi JT-S508CL-8S as the main 10G fibre switch (direct from Ali, for about 100 bucks).

For wired Ethernet and PoE, I have a couple of KeepLink KP-9000-9XHPML-X switches (I paid about 60 buck for each, they seem to cost around $85 now). I find that they work well and use them for 10/100/1000/2500 GbE switching and to power various devices (other switches, U7-Pro-XGS AP, Zigbee dongle, home automation server, rack fans etc).

The main splice box was about 60 bucks, 24 pigtails included.

From memory, 10G SFP+ fibre modules were about ten bucks apieces. (DAC cables are cheaper, 10G copper transceivers are more expensive.)

Plus various paraphenalia (wall face plates, keystone modules, more pigtails etc), all of which was pretty cheap.

Note that I was able to borrow a fusion splicer from a friend. Otherwise they seem to start at around 500 bucks; buying one would have been the single biggest expense.

I also run a 25G path from one point in my flat to my ISP. The cabling is exactly the same but 25G switching equipment and optics are considerably more expensive and less available than 10G.

To make it less hot, just use fiber optics.

Yes, but 10G really is the limit. I'll eat my boiled boots if 25GbE copper becomes anything you could remotely consider "common".

We are pushing multiple gigabits over 100 year old phone lines so never say never.

Not never, just not common. Why would you even want it when fibre already does better, cheaper?

I mean.. cat8 already exists but it will never be common because most people who dont make home networking a hobby just use wifi. Hell many many people now a days own only a tablet and phone and no desktop/laptop at all. Someone else in this thread mentioned motherboards with SFP ports on them and I cant believe that will ever be common because people can barely handle the many flavours of cables using USB C, how are…

Server boards typically use SFP, and for typical consumers you’re 100% correct that wifi is all that matters.

wow! that is way cheaper than what I would have expected. thanks china...

That, plus the existence of chipsets used in those switches, such as Realtek RTL8372/RTL8373 and RTL9303. Feature rich yet dirt cheap.

I particularly like per-pert PoE power monitoring on the RTL837x. I hooked that up to my netdata to get a full history of how much each device in my rack is drawing. Don't need a fancy PDU or separate power bricks for each device -- everything is powered by the $60 switch.

(This is a home network and I'm not at all bothered about single points of failure or lack of redundancy/failover.)
