Unfortunately the blog didn't link to the SFP+ module they're using, but everyone should know there's effectively 2 different generations of 10gbit sfp+ to ethernet^H10BASE-T modules. The old gen, labeled as 30 meters, draws ~3 W, and gets extremely hot (to the point it'll usually cause link flaps), and the newer gen, usually labeled as 100m or 80m, draws ~1.5 W, and runs much, much cooler. Example of the new gen: ht…

the AQC chips at least work with 1/10 only ports on older switches. And, it's not that hot, a single 1x1x0.5cm heatsink takes care of it. One large issue is that mikrotik's thermal design for SFP+ is a joke.

I don't understand the decisions to use RJ45 copper cable for anything higher than 1GbE, unless a) You like small computers and these only comes with RJ45 ports and 0 PCIe slots b) You enjoy fighting with super rigid cables, port flaps and hot modules I upgraded my home to full 10Gbps network at 2018. At that time: * 10Gbps SFP+ PCIe NICs (Mellanox CX3 and similar cards) are already dirt cheap ($15 for OCP adapted on…

Power usage is a good reason to stick with non-SFP ports. And you can use CAT5e with 10Gbps networks given the run is short enough. I run 2.5Gbps over CAT5e with no issues throughout my house (I don't need that much bandwidth except when downloading Steam games).

10Gbps fibre uses significantly less power than 10Gbps copper ethernet.

Any fs.com recommendations? (or, just look at the power numbers?) https://www.fs.com/c/10g-sfp-63?203=21772

I forget how I went about it, but I was able to get which chipsets their modules used. But honestly, unless they've sold out- 10GTek has been good for home use for me- at least for AOC and DAC. all my bidi stuff is second hand ciso off ebay

I'm extremely happy after upgrading my network to 10gbit copper ethernet. It was much more expensive than I thought it should be, but worth it even if I only max it occasionally. Now I can easily fully saturate my 10gbit ethernet doing a first Time Machine backup or transferring files to my M.2 SSD NAS which saves me waiting rime and is satisfying to watch. It's wild to me that 10gbit isn't the norm by now and tech p…

I honestly just don't need it. Part of that is my ISP options top out around 1200Mbps, certainly. But I also just don't need that kind of speed inside my home. Streaming video needs at most 20Mbps or so, and I don't do much in the way of large file transfers. And when I do large file transfers, it's usually from or to the internet, and my home network is not the bottleneck there.

I went a slightly different route. My switches are linked with 10Gbps SFP+ across the apartment, but it was way too late (and too much hassle) to pull proper in-wall fiber. Instead I used one of those ultra-thin (around 0.1mm), unshielded fiber cables, and just snaked it through door frames and taped it along the walls. I'm genuinely impressed this stuff exists, it makes retrofitting fiber into a finished space so mu…

And after getting 10Gbps working at home I was getting greedy, and looked at InfiniBand as well, 40Gbps and proper RDMA is very tempting compared to Ethernet. The catch for me was the practical side: IB needs PCIe slots and those chunky, inflexible cables. With most of my stuff being laptops, mini PCs and Macs, I just couldn’t see a clean way to route those or even plug cards in everywhere, so in the end the "door-frame‑friendly" skinny SFP+ fiber still won out for this apartment.

Yeah, 10GbE-over-copper switches are SO expensive. I bought a Ubiquiti enterprise switch for my home; 10Gb uplink and the copper ports are split between 2.5G and 1G. It's fine because only 1 or 2 clients can even talk 10G, and those are all across the house on Cat5 links anyway so they only negotiate to 2.5 even on a 10G port. As much as I wanted to "future proof" by having a 24 port 10GbE switch... why? I'll just wa…

> As much as I wanted to "future proof" by having a 24 port 10GbE switch... why? I'll just wait and buy one when I have a use for it. As much as I enjoy looking at those wiring cabinets where every cable is cut to exactly the right length to reach a single port on the switch, this is why I prefer to leave an amount of slack in the wiring: It's good to be able to pull different wires to different switches depending on…

This is what I ended up doing. A 2.5G switch for the few devices that can use it and a 1Gbit+PoE switch for all the other PoE and 1Gbit and less devices.

Has anyone tried the InvisiLight kits? They give you a 600 micron fiber optical link in the kit which you can hide down the side of carpet etc. I haven't tried it but a few YT vids made it look interesting. https://www.amazon.com/stores/InvisiLight/page/DFF3C042-0D2E...

Looks like a complicated and expensive way to avoid running copper. "Up to 1Gbps" is not confidence inspiring, if you really can't put holes in your walls I'd try a powerline kit first for 1/5th the price

This is the YT video I saw about it: https://www.youtube.com/watch?v=Z2FbzCyiNr4

He used different transceivers and got 10Gbs

Heh it's honestly wild to me anyone needs over a gig. My work has a one gig fiber line supporting hundreds of employees and usage generally remains below 10%. The high expense of 10gig is, in part, because it isn't widely necessary and the people buying it are willing to pay extra.

> The high expense of 10gig is, in part, because it isn't widely necessary and the people buying it are willing to pay extra. I think the price has more to do with where you live and how the market is structured than how necessary it is. In Japan where there is competition between ISPs, I pay about $40/mo for 10Gbps. Routers have also come down in price to where they are pretty affordable for consumers. I use a Ubiqu…

And if you don't need a router, you can get 10gbit ports for much cheaper than that. The Mikrotik CRS305-1G-4S gives you one copper 1gbit port, four 10gbit-capable SFP+ cages, and is ~150USD [0]. Their whole lineup of switches with SFP+ ports can seen here [1].

It's interesting how slow the uptake has been. 10GbE is from 2002, 24 years old. It's much worse than IPv6, at least we're up to 50% uptake there.

100 GbE is 15 years old too depending on which standard you think of. (The most common physical layer, SR4, is 11 yrs old)

Gigabit ethernet came much faster after 100 M.

> It's wild to me that 10gbit isn't the norm by now 10G was too big of a step up from 1G. The expense and power required made it unattractive. Only recently have the interfaces for 10G over twisted pair become reasonably low power. 2.5G and even 5G are in a much better spot. It's where I recommend most people start as a default.

expensive but not prohibitively so? https://www.aliexpress.us/item/3256807859212052.html https://www.servethehome.com/finally-a-cheap-8-port-10gbase-...

You can also get enterprise C3850 with 10G ports for ~100$, but they will be loud and power hungry.
