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…

At 10g, sfp+ switches are cheaper and more available than 10gbase-T switches. Fiber transceivers seem reasonable, but I could be off; I've only looked a little at fiber prices, I already have cat5 in the wall, so I'm on DAC for nearby stuff and twisted pair for other rooms for the forseable future. I don't really need 10G, but it provides a bit of fun.

for shorter runs you might even get 10G on cat5.

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.

If the cabling was installed before the drywall, good chance it's stapled.

Thats hideous.

Cheap, low-heat 10G copper is already here. RTL8127 NIC is under $50, $200 nets you a quality 4x switch (CRS304-4XG-IN).

I wish multiple-port 10G PCIe cards with this chip were available. I would immediately upgrade by Debian router from 2.5G to 10G. At the very least I would need a dual NIC.
