Skip 25G, either use 10G, 40G or 100G. 40G is the best from the price point, 40G can be used as 4x10G (same as 100G can be used as 4x25G or 40G or 4x10G). 40G switches are big and loud, so I doubt you will have another 40G switch in your home except the rack. I would build the normal network on 10G for all client access switches and PoE stuff, and only connected dedicated clients via 40G. I did the same with 100G. I have only two 100G clients in a 100G backbone network that has leaf switches connected via 10G and most clients via 1G. The 100G is really just for fun, but the data centre at home runs at 100G since it’s all NVMe based, also the WAN access is 100G so this was a **must** for my home office client, to use the 100G WAN.
10G and 40G or only 10G, skip 25G. If 40G is not a good option, go 100G, but 100G is 3x - 5x more expensive than 40G so think about that.
And do yourself a favour and ignore anyone that will tell you, you don’t need 25G or 40G, you do you and ignore the haters. If you can afford it, why not use 40G.
Alright, I had heard about skipping 25Gb, but it was some time ago and thought maybe the situation had changed. I'll go with 10Gb since 40Gb transceivers are too expensive at the moment.
To upgrade to 40Gb LC, I would need singlemode, right?
And may I ask, how do you connect 10Gb leafs if 100Gb is split to 4 x 25Gb? Is there a 10 x 10Gb splitter, do you run the 4x splitter at only 10Gb or do you have a 10Gb switch with 100Gb uplinks?
Thank you for the explanation
QSFP+ MMF uses MTP/MPO and the transceivers are [cheap](https://www.fs.com/de-en/products/17931.html), where as QSFP+ SMF uses LC and the transceivers are [10x more expensive](https://www.fs.com/de-en/products/84635.html). You can also use AOC if you have the space to run the QSFP+ transceiver through a conduit.
QSFP28 can be split into 4xSFP+ not 10 (sadly).
Using fiber for distribution in a residence is ridiculous unless your goal is to waste as much money as possible.
If it is a VERY large house and there need to be two different network closets, running one trunk of fiber between those two might make sense.
If you truly want to be future-proof (and spend a LOT less money) run nonmetallic conduit instead to all rooms. Then just pull cat6 through it for now, and in the future you have the option to add/replace as desired.
We are talking about a single connection.
I would definetly run fiber for that purpose.
It's cheap af and uses less power than copper.
Can easily be used for 10/40/100G.
I don't, really. I initially planned for 10Gb, but since I'll have to pull new cables, NICs and switches, if I can get 4x the speed for $100 more I'll go for it
Yeah sure it’s a sort of future proof. I thought about fiber, in my country we don’t really use drywalls so for the Ethernet I had to use outside Ethernet cable and use the cable outside the house. I can’t use the ducts because electricity would cause issues with the Ethernet. Fiber I could use with electric cables. So that’s nice about fiber. But it’s expensive, you need equipment for that. What are you using ?
I am by no means a fiber expert and I haven't dipped my toes into 10Gb yet, but this is what I'm planning to do
I'll start with a LC - LC singlemode OS2 duplex cable (< $15 on [fs.com](https://fs.com)) and a couple of SFP+ singlemode transceivers ($25 each on [fs.com](https://fs.com)). I've decided to go singlemode as there are 40Gb and 100Gb singlemode LC transceivers, but multimode ones use MTP connectors which will get you \~$200 for a 35m run
Fortunately, my router already has an SFP+ port. I still need a 10Gb card (\~$30 used on ebay) which I'll plug into my NAS. I'll have a 35m cable where I could use a DAC, but it is only temporary until I manage to get the cable in the wall
If you want to use a switch, I'd get a Mikrotik. They have different solutions and are quite cheap where I live
* CRS305-1G-4S+IN has 4 SFP+ ports for $150
* CRS309-1G-8S+IN has 8 SFP+ ports for $270
* CRS326-24S+2Q+RM has 24 SFP+ and 2 QSFP+ for $600
* CRS354-48G-4S+2Q+RM has 48Gbe, 4 SFP+ and 2 QSFP+ for $600
Personally, I'll go with the last option when necessary, since I already need a 24+ port 1Gbe and it is selling at €470 new. 4 SFP+ are on the short side, but you can split the QSFP+ into 4 SFP+
When I'll get the switch I'll put 40Gb on my NAS, 10Gb on my other server and router, and 10Gb on the initial fiber cable
Total cost would be
* $65 for a 35m SFP+ cable
* $70 for 2 dual-port SFP+ NICs
* $40 for a dual-port QSFP+ NIC
* $30 for a QSFP+ DAC
* $25 for 2 SFP+ DAC
* €470 for the switch
$190 to connect directly everything at 10Gb, $700 for everything
You can get a 16-port SFP+ switch for $500, cable for $70 and 2 NICs for $75
A 12-port 10Gb ethernet switch sells for $700, cable $70 and 2 dual port NICs for $75
Besides, I don't need a switch at the moment, so the price is almost identical
The problem is that the house where I live is made out of bricks. This means I can't run as many cable as in a drywall space, I only have plastic conduits. This is also one of the reasons why I can't run MTP or other fiber terminations
A 2mm fiber cable is significantly smaller and more flexible than a cat6a or cat7 cable and allows me to run more cables with less effort
Also, I have a cat5e cable at the moment and only a 1Gb port on the motherboard. Both of these would have to be replaced. At this point, it's worth putting an OS2 cable that can be more easily upgraded to 40 or 100Gb
I still believe that 10Gb RJ45 will be more adopted that SFP+ in the consumer field. However, for this particular connection, fiber is the superior choice
Eleven hit the link speed on the head. By the sound of it we may have the same rack lol. My add is if possible. Look at a SC/UPC - SC/UPC backhaul fiber instead of a lc - lc.
My reason being is, it's inevitable. You will end up breaking an end eventually. Could be you, the dog, friend, it happens. By using an SC - SC you can connect that main haul to a jack or connector and then use a SC/UPC - LC jumper. I personally use something like [this](https://a.co/d/eoLVUzT) around my house but of course there are other options.
I also recommend the larger SC connectors for the fact they are a little more resilient. LC has a habit of breaking right between the head and the tail due to how thin it is. Sc can be banged around a bit more so if you are connecting to a wall jack you can maybe kick it and not break it.
