    Japan’s current fiber-optic commercial internet connections use optical fiber transmission windows known as L and C multi-core fiber (MCF) bands to transport data long distances at record speeds. Meanwhile we (USA) have fiber back to copper and Cat3 for the last few hundred feet in most cities at best making the entire idea into a bottle neck.

        Yes, but nowhere compared to the Netherlands and Denmark

        Ofc the size of the countries makes it easier.

        No, the average internet download speed in the United State is about 171 Mbps. Though disclaimer, I’m not sure of the exact reliability of that number, different sources are reporting quite a range of speeds, though I don’t see any under 100 Mbps average and I see many reporting well above this. You’d also have to consider median vs average since people with fiber sitting at gigabit speeds may be dragging that number up, median may be lower.

        There are certainly some areas, especially rural, that struggle though. And upload speed is often much worse unless you have fiber. Major cities are definitely getting much better than 10 Mbps down though.

        Cat 3 isnt actually a thing, but people call house phone wiring that. Runs DSL quite well.

          Cat 3 is a thing and is basically unshielded twisted pair. You can abuse it quite a bit from its voice grade days to cram a few hundred megabits of VDSL over it if it’s only from your house to the curb.

      There are a lot of very good reasons to switch back to copper for the last portion of a run. I highly doubt that consumer internet in Japan is terminating fiber directly into peoples’ computers. Fiber is a lot more expensive both for the line, to run it, more prone to breakage, the network cards are more expensive, etc. It’s really not needed for most purposes.

      Also no one uses cat3 for data and it can’t be run for ‘hundreds of feet’. And LC fiber IS used in the US - that’s a kind of connector not the kind of fiber.
