Fiber optic internet can be broadly classified into:
FTTH (Fiber to the Home): Direct fiber connection to residences.
FTTB (Fiber to the Building): Fiber reaches the building, with internal wiring distributing the connection.
FTTN (Fiber to the Node): Fiber extends to a central node, with the final connection using copper cables.
FTTC (Fiber to the Curb): Fiber reaches the curb near homes, and the connection from the curb to the home uses copper or coaxial cables.
