Do I need a special modem for fiber optic internet?

Written by Editorial Team | Last Updated: August 2026

Fiber-optic internet infrastructure does not utilize a traditional telephone or cable modem; instead, it requires an Optical Network Terminal (ONT) provided directly by your internet service provider. Because fiber transmissions travel via light signals rather than electrical voltages carried over copper wires, the ONT is an essential piece of hardware that terminates the fiber line and converts optical pulses into standard Ethernet data packets. Most modern fiber providers supply this terminal as part of the standard installation package, which then connects directly to your personal Wi-Fi router.
