While fiber internet doesn't require a modem, you still need a router to distribute the connection across your network. Your router works hand-in-hand with the ONT, taking the internet signal and spreading it wirelessly or through Ethernet cables to all your connected devices. Routers designed for DSL (which uses phone line inputs) or cable (which uses coaxial inputs) won't work. Your ONT handles signal conversion, eliminating the need for a traditional modem altogether. Think of the ONT as a high-tech bridge between your ISP and your internal network – but engineered specifically for fiber's unique data. A standard router may be enough for small to medium homes, but larger homes or those with complex layouts (say, houses with thick walls or multiple floors) can benefit from fiber-ready routers.
