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 have access to internet speeds that can exceed 2.5gbit/s.

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 expensive. And then, there's the big one - PoE. That's why I also ran CAT6A next to each duplex to rooms and they're more or less for APs in the house. Overall it's definitely future proof and fantastic, but also a bit expensive if you wanna engage that fiber through the house. Pulling the cable itself isn't much of a cost at all and I recommend it.

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.

Totally agree, I went to fiber years ago, and the decrease in latency makes it _feel_ so much faster than 10G copper, it is not funny. Besides, if you put in the "good stuff" them moving to 40G and beyond is not a problem later on. Like others said, just add a copper line for POE devices, but for systems... its fiber all the way.

There are probably still a lot of cases where you would want PoE though right? Cameras, WAPs, etc.

I have ten gigabits throughout most of my house, and you're right: copper is not happy pushing ten gigs.

My 10 gigabit thunderbolt dongle weighs about a pound, and I think 90+% of that weight is just heatsink. If I've had it plugged in for awhile, if I accidentally touch that dongle it actually hurts because it's so hot. I cannot image that much heat is good for, well, anything.

I have another Thunderbolt dongle that has an SFP+ module, so I ran a fiber line from my switch to my computer, and that runs considerably cooler. That's what I use nowadays.

How many consumer devices have an ((Q)SFP(+)) optical cage?

If you're in their pulling stuff anyway, sure, do some OS2, but for most people, for most devices, Cat 5e/6 is more useful, especially since you can do POE(+(+)) over it as well. 5e/6 gets you 10GbE to 55m, and 6A to 100m.

I would be grateful and happy to have gigabit Ethernet with cat 6A in every room instead of this single landline phone jack and/or coaxial cable. The most important thing is a good conduit in place when the house is built.

you should be putting in conduit -- either smurf tube, emt, sch40, or similar. can pull whatever, and more importantly, if a cable is damaged by an overly zealous gorilla during installation, it can easily be fixed and replaced.

> ethernet at 10gbit/s and its really high consumption and heat

Do you mean Ethernet cables get hot? Or just the networking equipment pushing that data.

I ask because I’ve never heard of Ethernet cables getting hot.

You cannot do PoE over fiber.

> the off ramp is clearly happening for ethernet

You should be running both.

If you are being smart about it your planning distributed switching (fiber to media boxes with power).

From a pure networking stance, fiber is the way to go. But POE continues to have more and more uses (doorbells, cameras, sensors, lighting controls).

You still need to power things.

Often that will mean running both Cat6A and fiber.
