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…

For may be specific professionals? For Prosumers I don't see the need even if I have access to 25Gbps Internet.

For majority of home usage it will all be WiFi. WiFi 7 has gotten to the point where prosumers are happy with its performance. WiFi 8 and 9 will further improve in that direction for reliability and speed.

With PoE, router and everything else Ethernet is still clearly the easiest choice. And as mentioned we now have sub 2W 10Gbps Ethernet. What will likely happen is that 10Gbps becomes like 1Gbps Ethernet, it will stay here for 10-20 years until something happen in the future that needs extra bandwidth.

May be in 10 years time 10Gbps could be done under 1W.

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 standar…

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

25G is definitely a thing over copper, just not over Ethernet :)

> I do think that the average home won't need more than 2.5gbps, pretty much indefinitely Yeah I'm not seeing a need for fiber or anything more than CAT6. Most household devices use WiFi and I think that will continue. People don't like wires. They're unsightly, collect dust, get tripped over, etc. I already have coax cable and telephone wiring in my walls that's unused. One computer in my house has a wired network c…

That's fine.

In my house though, everything except printers, phones and laptops uses Ethernet. It just works and it's better.

I'd settle for 1 Gbps with a real IP address (UK)

I believe BT Fibre (FTTP) provides a real address (as in not CGNAT).

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…

Finishing up the same thing. 2x OS2 pairs with 2x CAT-6A to each drop, all coming together to the network closet. Gives me fiber for bandwidth and copper for PoE. Figured it was smarter to do both than compromise to either one, and surprisingly the fiber was cheaper than the copper to pull.

Fiber is much slimmer and takes less effort to pull.

> OS2 single mode duplex throughout the house, all converging to a trunk which is available in three locations for equipment. What do you mean by "trunk which is available in three locations"? Usually cabling is home-run to a single, central patch panel. A cable (fibre, copper) would usually have one end in a room's wall outlet, with the other end at a patch panel: how would you have a cable one end at three location…

that's exactly what I have. I have a hub in the attic with a small rack where all the wall runs end up at both rooms' fiber and CAT6A, there's a small 10G switch with PoE there for CAT6A (for APs and RJ45 outlets). There's also a fiber patch panel there where those rooms' ones connect to. Trunk starts there as well, in a fiber rack shelf which goes to the basement. In the attic I patch trunk to walls and the switch. In the basement trunk ends up in another patch panel (a cabinet on the wall) from which I run fibers to the rack with all the equipment. Thing is, that patch panel cabinet on the wall is also hosting another trunk which goes to the garage, where there's a third patch panel (in a cabinet on the wall) from which I'll soon connect to rack(s) there. Eventually, in the basement i'll just patch trunk to trunk so that way i'll just hoist all the network equipment to racks in the garage. By having three hubs like this though, I can do whatever.

In principle it sounds simple, but in practice I got lost in my own way too many times. Just glad that it's over, hahah.

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

Having debugged flaky 100GE links on multimode fibre: absolutely the f*ck not. Unless forced by compatibility needs, you install single mode, end of evaluation of benefits and drawbacks. SMF just works. MMF is dead for any and all greenfield fixed installation.

The sibling posts have already pointed out the pricing has mostly equalized at this point too, especially if you're more realistic and look at 10G or 25G. (Or just buy a pile of used 100G CWDM4 transceivers off eBay.)

PoE is extremely useful though. You can stick PoE wifi access points straight to the wall, no wires visible.

Please avoid the use of the term “hub” here as it already was defined elsewhere https://en.wikipedia.org/wiki/Ethernet_hub

A switch differs from a hub, a patch panel differs from a hub. Hopefully you haven’t touched one since affordable fast Ethernet switches hit the consumer market.
