Abstract: PURPOSE: An optical network system and a method which controls the optical network system are provided to make a symmetric terminal and an asymmetric terminal coexist. CONSTITUTION: An optical base station (110) controls a passive optical network in which one or more symmetric optical subscriber terminals (120) and one or more asymmetric terminals (130) coexist. The optical base station commonly uses one optical line terminal (OLT) as a transceiver of the one or more symmetric optical subscriber terminals and the one or more asymmetric terminals. In case one or more output signals which are outputted from a physical medium attachment (PMA) are an asymmetric structure, the optical base station uses at least one of the one or more output signals.

Abstract: PURPOSE: An ONU(Optical Network Unit) and a method of operating the ONU are provided to control an upstream optical signal strength based on a loss signal of downstream data and transmit upstream data generated based on the controlled upstream optical signal strength, so that an OLT(Optical Line Termination) may receive the upstream data at a constant optical signal strength. CONSTITUTION: A received data processor(201) includes an electrical signal converter(203), a power amplifier(205), and a limiting amplifier(207). The electrical signal converter converts, to a current signal, an optical signal of downstream data received from an OLT via an optical splitter. The power amplifier pre-amplifies, to a voltage signal, the current signal output from the electrical signal converter. The limiting amplifier outputs received data by converting, to a digital voltage signal, the voltage signal output from the power amplifier. A transmission data processor(209) includes a measurement unit(211), a determination unit, an E/O(Electric-to-Optic) conversion controller(215), and an E/O converter(217). The measurement unit measures a downstream optical signal strength of downstream data received from the OLT. The determination unit determines an upstream optical signal strength based on the measured downstream optical signal strength. Specifically, the determination unit compares the measured downstream optical signal strength with a predetermined downstream reference strength to calculate a loss signal of the downstream data, and to determine the upstream optical signal strength based on a predetermined upstream reference strength and the loss signal.

Abstract: A method for saving power of an ONT(Optical Network terminal) and an OLT(Optical Line Terminal) in an optical access network is provided to decrease the management cost of a network operator as well as save the power of a subscriber by operating an ONT(Optical Network terminal) and an OLT(Optical Line Terminal) in a software manner without using an additional physical device or machine. An ONT is switched to a power saving mode, and cuts off the power for all functions except a controller which monitors and controls external input(S304). It is judged whether or not a request condition for the switch into an active mode is satisfied at the power saving mode(S305). The ONT transmits a wake-up signal to an OLT(S306), and is switched to an active state. The ONT performs a normal operation.
