摘要： A dynamic upstream bandwidth allocation scheme is disclosed, i.e., limited sharing with traffic prediction (LSTP), to improve the bandwidth efficiency of upstream transmission over PONs. LSTP adopts the PON MAC control messages, and dynamically allocates bandwidth according to the on-line traffic load. The ONU bandwidth requirement includes the already buffered data and a prediction of the incoming data, thus reducing the frame delay and alleviating the data loss. ONUs are served by the OLT in a fixed order in LSTP to facilitate the traffic prediction. Each optical network unit (ONU) classifies its local traffic into three classes with descending priorities: expedited forwarding (EF), assured forwarding (AF), and best effort (BE). Data with higher priority replace data with lower priority when the buffer is full. In order to alleviate uncontrolled delay and unfair drop of the lower priority data, the priority-based scheduling is employed to deliver the buffered data in a particular transmission timeslot. The bandwidth allocation incorporates the service level agreements (SLAs) and the on-line traffic dynamics. The basic limited sharing with traffic prediction (LSTP) scheme is extended to serve the classified network traffic.

摘要： A hybrid optical transceiver module and a passive optical network comprising the same are provided to package an LD portion in a TOSA structure and package an SOA, a PD, and a WDM coupler in a PLC structure to make two packages into one, thereby solving an optical alignment problem caused by a narrow optical emission angle. A hybrid optical transceiver module is comprised of a first package(100) of a TOSA(Transmitter Optical Sub-Assembly) structure and a second package(200) of a PLC(Planar Lightwave Circuit) platform structure. The first package includes an LD(Laser Diode)(110), a first MPD(Monitor Photo Diode)(130), and a lens(120) for concentrating a transmission optical signal outputted from the LD to emit the transmission optical signal to the outside of the first package. The second package includes an SOA(Semiconductor Optical Amplifier)(210), a second MPD(240), a PD(Photo Diode)(220), an optical waveguide(232), and a WDM(Wavelength Division Multiplex) coupler(230). The SOA receives the transmission optical signal emitted from the first package to emit a high-power transmission optical signal to the outside. The second MPD monitors the high-power transmission optical signal. The PD receives a reception optical signal inputted through an optical fiber(250). The optical waveguide transmits the high-power transmission optical signal emitted from the SOA to the optical fiber. The WDM coupler transmits the reception optical signal to the PD and divides the high-power transmission optical signal and the reception optical signal. The first package and the second package are coupled with each other through optical alignment. A PON(Passive Optical Network) system includes a splitter for transceiving signals to an ONT(Optical Network Terminal) separatedly. The signal is in a TDMA(Time Division Multiplexing Access) type.

摘要： A PON(Passive Optical Network) is provided to solve a problem that an installation cost of a subscriber increases because a high-priced analog distribution feedback laser should be used. A CO(Central Office)(210) generates downlink optical signals and receives multiplexed uplink optical signals. Plural subscriber units(240-1-240-M) receive a corresponding downlink optical signal and generate a sub-carrier channel including electric data of an allocated frequency. Converters(230-1-230-N) convert the sub-carrier channels into the uplink optical signals. A multiplexing/demultiplexing unit(221) demultiplexes the downlink optical signals which have been multiplexed in the CO(210) and outputs them to a corresponding converter, and multiplexes uplink optical signals received from the converters(230-1-230-N) and outputs them into the CO(210). Intensity separators(235-1-235-N) separate a downlink optical signal of a corresponding wavelength and output the same to corresponding linked subscriber units, and output sub-carrier channels received from the corresponding linked subscriber units to the converters(230-1-230-N).
