    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.

      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.
