My Internet provider just installed a 2,5/1Gbps Internet connection and I’ve asked the guys to run a couple of their fiber to connect my router (HP Prodesk with OPNsense) to my server. I didn’t know that the fiber is single mode and all the SFP+ sold used now seems to be all for multi mode fiber (www.bargainhardware.co.ukfor example). The cable is about 30m, can I use a 810nm SFP+ or is it definitely better to use a 1310nm?
I’ve only looked briefly into APC/UPC adapters, although my intention was to do the opposite of your scenario. In my case, I already had LC/UPC terminated duplex fibre through the house, and I want to use it to move my ISP’s ONT closer to my networking closet. That requires me to convert the ISP’s SC/APC to LC/UPC at the current terminus, then convert it back in my wiring closet. I hadn’t gotten past the planning stage for that move, though.
Although your ISP was kind enough to run this fibre for you, the price of 30 meters LC/UPC terminated fibre isn’t terribly excessive (at least here in USA), so would it be possible to use their fibre as a pull-string to run new fibre instead? That would avoid all the adapters, although you’d have to be handy and careful with the pull forces allowed on a fibre.
But I digress. On the xcvr choice, I don’t have any recommendations, as I’m on mobile. But one avenue is to look at a reputable switch manufacturer and find their xcvr list. The big manufacturers (Cisco, HPE/Aruba, etc) will have detailed spec sheets, so you can find the branded one that works for you. And then you can cross-reference that to cheaper, generic, compatible xcvrs.

The problem is the installation of the connectors. They’ve welded the fiber the SC/APC pigtails, I wouldn’t be able to do that.

That would be very very generous of you; in the fiber section I’m pretty ignorant and I’m worried to purchase wrong items 🙈
I quickly looked up the HPE/Aruba transceiver document, and starting on page 61 is the table of SFP+ transceivers, specifically describing the frequency and mode. At least from their transceivers, J9151A, J9151E, JL749A, and JL783A would work for your single-mode, 1310 nm needs.
You will have to do additional research to find generic parts which are equivalent to those transceivers. Good luck in your endeavors!
Thanks a lot! It seems that this from fs.com in the non Aruba compatible brands costs 32€ Thanks again!
Edit: And I’ve even found the LC/UPC to SC/APC cable!
