Interesting observation about power use. How close do you think we are to it being practical to wire your whole home with fiber instead of CAT6 or whatever? If you're providing all your own equipment, are willing to purchase a high-end splicer for maintenance, etc.

For laptops I assume you need USB/Thunderbolt adapters. (Still no SFP+ or SFP28 module for Framework?)

For desktops you'd use an SFP28 card (taking up a PCIe slot).

For devices like Raspberry Pi's, etc. you'd use... local RJ45 switches with optical uplink ports?

You can just do a mix.

Most of my devices only need 1G or even 100Mbps. No reason to switch to fiber. 1G/2.5G copper ports don’t use that much power.

For 10G+ things, it’s fiber or DAC first if possible then RJ45 if it’s the only option.

Then my backhaul between rooms is just single mode fiber, good up to 800G. Plug in a small switch at the end and you go back to RJ45 and PoE.

I only have 10G though (to transfer large files/RAWs between my computer and my storage). Something faster would be nice because NVMe SSDs can go 50G+ but that equipment is pricey and power hungry.

If you need 1G or 10GB over copper you can just use a SFP or SFP+ media converter in a 25GB SFP28 switch port. If you have a POE requirement, say for video cameras you either use a dedicated 1GB POE switch or power injector. A 10GBASE-T (RJ-45 copper) switch consumes 3-12 watts per port and a 24 port switch will idle at 50 to 60 watts and run hot. SFP+ and SFP28 ports use under 1 watt per port. I would never recommend a 10GBASE-T copper switch for any use case in this day and age, home or enterprise.

Wiring ports for humans to use in a flexible and future proof manner (as in a single family home, for instance) gains a lot of utility with PoE.

The convenience and flexibility of PoE would always push me towards copper wiring.
