An optical network system for providing wireless broadband services is provided. The optical network system may include an optical line terminal (OLT); and at least one optical network unit (ONU), wherein the OLT broadcasts downlink data to the ONU with the aid of a light source and the ONU transmits data to the OLT through a predetermined optical wavelength. Therefore, it is possible to easily identify what terminal has transmitted an optical signal to a center based on the wavelength of the optical signal and to reduce the consumption of optical fibers between the center and a number of access points (APs). |
