Single mode fiber cable: which SFP module? (lemmy.world)

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?

Regarding future proofing, I would say that anyone laying single pairs of fibres is already going to constrain themselves when looking to the future.

It could be right, but it depends on what people can run in the conducts. I was lucky to be able to pull those 2 cables. On the other hand, this is a rent apartment that I will soon leave :D
