I wonder what is use case for this network. At my home I only use optics for long run, more for galvanic isolation, as electric charge could destroy electronics. All servers are concentrated in single room. Clients use miniPCs. Rest of the house is wired with 2.5Gb ethernet and wifi6, anything faster and expenses grow exponentially.

I second this. ~$1375 vs under $200 for an Ethernet run. Expensive project just to be able to say "I did it".

This article is great overall, but there is some stuff you should do differently, if you're wanting to follow in the author's footsteps:

1. Just use UPC connectors everywhere unless you have really good reasons not to.

2. Use single mode fiber (SMF) everywhere, including internal wiring. SMF is infinitely scalable for future needs, multimode (MMF) is not. These days the cost differences for cabling and optics is negligible. In fact, SMF cabling is often cheaper than MMF. And no, you generally won’t have to worry about attenuating signal.

Also, in my extensive experience, FS.com optics modules are typically better manufactured and more reliable than OEM modules.

I resisted the "cheap chinese" modules for a long, long time, but then discovered that most of my uplink carriers used them.

It's been years now. I've had many Cisco OEM, Dell OEM, and a couple from another 3rd party manufacturer go bad, but I have yet for one FS.com SFP to go bad. I've got several hundred deployed in a wide variety of environments, from great (cool, clean areas) to bad (hot, dirty areas).

Not every hobby has to be cost optimized. I’ve spent thousands on climbing equipment that I never took full advantage of.

Sometimes people have money to burn and want to do something for the fun of it.

I think one major use case in this particular scenario is that the author has one 25 Gbit/s and one 10 Gbit/s internet service. If you want to make the most use of this fibre is the only way to go.

For those wondering, as the OP didn't mention it super-clearly imho - but his internet provider is able to do 25gbit [1] for CHF 69 a month (+ CHF ~340 set up cost)

CHF 1 ~= USD 1 these days

Question for OP:

Why did you build such an expensive "router" - you justify it by saying you also want to run PiHole, but you probably could have done this whole setup much cheaply

It's very likely "because he can".

25Gbps would be hard to saturate with an NVME SSD. Even if you like to mirror hard disks to remote locations all the time, you can just RSYNC, and then your needs are limited to the rate of change.

I'm getting a 10Gbps from the same provider, and even that is not likely to saturate, and I'll only have 1Gbps CAT6 links. The main benefit is that the clients are absolutely independent, i.e. downloading a Linux image can't affect someone's video conference, since each client can only pull 1Gbps of 10Gbps total.

The author's ISP delivers up to 25/25Gbps connections (and 10gbps connections for the same price as 1gbps connections, about $65 dollars per month converted) so if he is planning on using such a high bandwidth uplink, I don't think ethernet makes a lot of sense.

If I had a 10gbps uplink for that price, I'd certainly look into getting more out of my network than just standard ethernet. 10gbit ethernet at least, though fiber may be easier to install depending on the size and layout of the house.
