Yeah, 10Gb ethernet runs hot. I just rewired the house with 10Gb (we have 8Gb FTTP) and it's kind of upsetting how hot my Thunderbolt dock gets.

- Gigachad 3mo agoI looked in to it and it seemed like 10gbit was much better over fiber. Ended up deciding that 2.5gbit is plenty. The 2.5 gear is significantly cheaper and runs cool.
- jfb 3mo agoYeah, I use DAC for the desktop and fibre between floors. It's just the Mac's desktop that uses RJ45 copper.

- drnick1 3mo ago> I looked in to it and it seemed like 10gbit was much better over fiber. Yes, except that most devices use Ethernet. So, at the end of the day, you still need Ethernet cables unless you want to deal with an additional switch or converter in every room.
- Gigachad 3mo agoIndeed, that's largely why I decided 10gbit at home isn't really worth it. The current 10gbit ethernet stuff is expensive and power hungry, the enterprise stuff is hard to use on consumer gear. And the only real use case is super fast access to a nas.
- kstrauser 3mo agoI got it solely because our ISP bumped our home fiber to 10Gb and it would’ve hurt my soul for the router to be slower than that. And hey, if you’ve already got a router with 10Gb ports available and ready to go…
- eqvinox 3mo agoFiber/10Gbase-*R is Ethernet too. Please say copper/RJ45/base-T when you mean copper/RJ45/base-T.
- sekh60 3mo agoThank you.
- antonvs 3mo agoExcuse me, I believe you mean GNU/copper/RJ45/base-T
- eqvinox 3mo agoMy copper/RJ45/base-T is running musl libc + busybox!
- fluoridation 3mo agoIf you want to ackshually, both fiber and copper are empty pipes that can carry any layer 2 protocol, and are not inherently Ethernet. They only become Ethernet cables when they're connected to terminals that pass that protocol through them. Unless we're defining some networking standard, "Ethernet cable" is a perfectly acceptable term. Everyone will understand what is meant. The added specificity you're asking for doesn't improve the quality of communication.
- eqvinox 3mo agoThat's why I added base-*R/base-T. And particularly for 10GE the heat and power problems are due to the copper transceiver DSPs. And people nerdy enough to run 10GE at home might well run fibre. So, no, the specifity is needed and useful.
- fluoridation 3mo ago>That's why I added base-*R/base-T. You're still talking about a cable. The cable may be compatible with those standards, but you can put anything through it. It's just a physical connection. >And people nerdy enough to run 10GE at home might well run fibre. So, no, the specifity is needed and useful. No, because if you say "which do you want? Ethernet or fiber?" no one will look at you like if you asked if they want salt or beef. It's technically incorrect, but everyone will understand what is being asked.
- Dylan16807 3mo ago> every room I disagree with that for two reasons. First, my central switch is probably capable of both copper and fiber. Second, how many wired devices do you have spread around your house? Let's say I have an above average number of devices: a router, a NAS, two access points, and three desktops. Router, NAS, and one access point can all be adjacent to the switch and avoid any conversion hassle. The desktops are using fiber so no conversion hassle there. That leaves one copper cable or converter needed for the other access point.
- krisroadruck 3mo agoI guess I have rather overestimated what a normal amount of wired devices is based on my own sample size. That or the opposite is happening with you. My house has a POE doorbell, several POE cameras, 2 TVs that each get a connection to their attached android TV boxes, Wife's office gets a pair of connections, ditto with mine, then you've got the APs for the wireless bits + a few servers in the rack with the networking equipment. Mind you I know I am on the high side, but I use that as the reference point. I'd figure a normal house would have 4-5 wired connections to my 20ish.
- Dylan16807 3mo agoIn that situation I'd basically consider the doorbell and cameras as a separate install. That mainly leaves the TVs, which I would just throw on the wireless but for wiring I'd still say you run it to your central switching spot that handles both copper and fiber.
- trumpdong 3mo agoIf you have a fixed computer or NAS, stop making excuses and install a 10G fiber card in it. If you have a laptop or TV it probably doesn't need 10G.
- bjt12345 3mo agoFibre requires conduit with specific radius bends, making it difficult to route through a house.
- mscdex 3mo agoYou'd be amazed what exists on the market these days. For example, the pre-terminated InvisiLight fiber cabling is 0.6mm in diameter and has a 2.5mm bend radius. I've personally installed this cabling while making many 90 degree (and sharper in some cases) bends without any issues. That makes it easy to hide and trivial to fit right through doorways and other tight spaces too.
- rescbr 3mo agoHaving cabled my apartment with Cat 6 definitely made me prefer fiber, it would have been a breeze instead of pulling thick cables from my office to other rooms. Cat 6 also shouldn’t be bent or you risk it going out of spec, and modern fiber nowadays have bend radius comparable to (or even smaller than) Cat 6. I see how sloppy some FTTH installs are and they all work fine, and this is for light that travels for long distances. The only advantage copper has is PoE.

- drnick1 3mo ago> If you have a fixed computer or NAS, stop making excuses and install a 10G fiber card in it. It's hard to justify when Ethernet is catching up. Most new motherboards have a 2.5G port. High-end motherboards have 10G Ethernet ports. SFP cards take space, are ugly, and need directed airflow to stay cool. They are not worth it for a 4x increase in bandwidth at best.
- DrPhish 3mo agoI redid everything that matters in my house/homelab with DAC cables for exactly that reason. Order of magnitude difference in watts and heat

- znpy 3mo ago> it's kind of upsetting how hot my Thunderbolt dock gets. I have seen the same with just usb-c multi-port dongles for macbooks (the ones they give you at work along with the macbooks). in fairness to the docs/dongles though, they have an incredible amount of features that would have been science-fiction twenty years ago.
- bartvk 3mo agoWhich dock (brand/model) did you get?
- bjt12345 3mo agoHopefully short-run 10GIGE-T might get cooler with better DSP, but for long runs I think it will remain fibre.
