The answer is no; fiber internet doesn't need a traditional modem. A standard cable or DSL modem's job is to convert electrical signals into digital data that your devices can understand. But since fiber transmits data as light instead of electricity, there's no need for that type of. Instead, fiber relies on an Optical Network Terminal (ONT) to decode the signal from the fiber lines into something usable by your devices. In this way, an ONT serves the same basic function as a cable modem. However, ONTs tend to be much larger, so they are typically installed in closets, garages. The ONU connects directly to the fiber line entering the home. l It supports high speeds, often reaching 1 Gbps or more. l. While there are 137 residential internet providers in the state, most homes only have access to 1–2 options above 25 Mbps.
