Techopedia explains Fiber-Optic Service (FiOS)
FiOS works through a point-to-multipoint network architecture. A single-mode fiber is stretched to the FiOS provider facility. From there, it is distributed to different subscribers through an optical splitter. An optical network terminal (ONT) is installed at the subscriber’s end to convert the fiber based light signal into equivalent signals for the copper based infrastructure found in most homes.
FiOS was initially designed for home users but is now available for commercial use.
