Your 10G SFP modules have a power budget of 6.2 dB https://www.fs.com/products/11603.html Assuming zero losses at the fusion-spliced pigtail connectors this would be enough for a ~12.4 km fiber link (~0.5 dB attenuation per km). With the connectors I linked, 0.2 dB loss at each end, the power budget is reduced to 5.8 dB which would be enough for a ~11.6 km fiber link.

As you see this makes no difference for a residence where all your links are much shorter than even 0.1 km ! All I'm saying is you had cheaper options than buying a fusion splicer. But I understand you for buying it — it's a cool tool to have fun with, and to get some experience. I would have probably done the same since fiber is also a hobby of mine (though I reiterate I have never built a cable myself) :)
