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.

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.
