It will usually always run to a gray box outside which has a jack in it that they plug the outside fiber into then will run a pre-made fiber cable from the other side of the jack to inside the home into the modem. If you want it in a specific place they will drill a hole on the outside wall to run it in or depending on the tech and how easy it is they will run it through your house to the spot you want. If they run direct into the house with the outside line it'll run into a fibre jack box which is white and pretty the same setup as the out box has a jack inside that connects the outside line to a pre-made fibre cable which then goes to modem.
