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 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!
