It is technically fiber optic, but the connection between the home and the distribution box still relies on copper cables.

It’s not technically fiber at all. Your connection is copper, it doesn’t matter how fast the internet downstream is, you will always be limited by the copper.

For those that aren’t sure if you have fiber, the fiber will literally run into your “modem” (your Optical Network Terminal or ONT) and it will be incredibly clear that you have fiber. The wire is incredibly thin and they will warn you about bending it too much. If you don’t have that then you don’t have fiber.

Edit: to be more clear, just because there’s a 50Tb connection between the US and Europe doesn’t mean that you have a 50Tb connection. Downstream speeds do not matter to your home connection.

And if the connector breaks, you can't simply fix it at home like you would do with copper. You'll spend an internet-less weekend until the technician fixes it.
