But why stop at 10 years? If the theoretical bandwidth limit of SM Fiber is above 100 Gbit/s then there is simply no way that a household will need more internal bandwidth than that. Even for the next 20-30 years, because other technologies (like SATA) will be the limiting factor.
I believe this could be a case of future proofing that will actually last 30-40 years, no?
10 years is the guideline because you can't predict most of the future, but, you can predict the physical wear fairly well. It's likely that the plastic terminations will be iffy by that point basically, which means reterminating, or, running new fiber, and most of the time you'll just run new fiber.
