Abstract: A method and an apparatus for supporting a multi-transmission speed of a PON(Passive Optical Network) system are provided to reduce costs for replacing hardware and maximize the efficiency of a network operation. A PON MAC(Medium Access Control) unit(210) outputs parallel data having data repeated by the pre-set number of times via a transmission interface of a plurality of lanes according to a transmission speed desired to be generated for a PON, and in this case, the repeated data is disposed to be adjacent in the parallel data. A serialization unit(220) latches the parallel data provided via the transmission interface to a serial data clock to generate serial data having a different data width for each transmission speed. The PON MAC unit converts a general packet provided from a communication provider network or a subscriber network into a PON frame, and makes the PON frame the parallel data. An optical conversion unit(270) converts an electrical signal of serial data by transmission speed, which is to be generated, into an optical signal and outputs converted optical signal to PON network.

Abstract: A passive optical amplifying circuit and a bidirectional optical amplifying optical communication system including the same are provided to amplify a downlink signal or the downlink signal and an uplink signal optically without additional power supply, thereby realizing a miniaturized PON(Passive Optical Network) system by being integrated together with an optical distributor in a miniaturizing way. A first WDM(Wavelength Division Multiplexing) coupler(110) separates an uplink signal of second wavelength from an OLT(Optical Line Terminal) transceiving end signal consisting of a downlink signal of first wavelength and a pumping signal of third wavelength for amplifying the downlink signal. A partial WDM coupler(120) inputs the OLT transceiving end signal to divide the pumping signal into the same wavelength of the first and second pumping signals. An amplifying medium(130) inputs the first pumping signal and the downlink signal, and inputs the second pumping signal to amplify the downlink signal. A second WDM coupler(140) multiplexes the amplified downlink signal and the uplink signal.

Abstract: A wavelength division multiplexing passive optical network system is provided. A central office generates a multi-mode light having a mode interval equal to a period interval of a multiplexing filter of the remote node and the multi-mode light is used to control a wavelength of an uplink transmission optical signal of the optical network unit. A remote node multiplexes the multi-mode light with the multiplexing filter to transmit the multiplexed multi-mode light to the optical network unit and demultiplexes the uplink transmission optical signal to transmit the demultiplexed uplink transmission optical signal to the central office. An the optical network unit generates the uplink transmission optical signal by modulating a data signal with a Fabry-Perot laser which uses the multiplexed multi-mode light as an injection optical source. Accordingly, it is possible to control a wavelength of a transmitter of the optical network unit by using the injection optical source generated by the central office.
