Does fiber optic cable no longer need a router
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. This technology change brings many benefits. Your ONT handles signal conversion, eliminating the need for a traditional modem altogether. The ONT is usually installed by your internet service provider (ISP) and is responsible for converting the light signals into electrical signals. The short answer to this question is that you do in fact still need a modem to work with fiber internet.
