The most significant difference is the hardware each router connects to. A fiber router is designed to interface with an Optical Network Terminal (ONT), which is the endpoint for your fiber-optic line. It acts as the central hub for distributing the high-speed internet that comes into your building via light signals traveling through fiber-optic cables. Its main function is to translate. A fiber router is designed to work specifically with fiber optic internet connections, providing faster and more reliable speeds compared to a normal router that typically works with traditional broadband connections. Fiber routers are able to handle higher bandwidth demands and offer lower. This guide breaks down everything you need to know about fiber routers, ONT fiber equipment, and other essential components to help you make informed decisions when you compare internet plans. ONTs are for fiber; modems are for traditional broadband.
