Outline of Final Research Achievements |
For the progress of the information society, the optical packet transmission system is important for constructing a flexible and efficient information network. To enlarge the transmission speed and distance of the optical packet transmission, the high-speed waveform shaping technique (electrical dispersion compensation: EDC) was proposed and verified. For the EDC enables to respond to the data packet with high-speed, we devised a new control technique that combines the accurate analog control with a high-speed waveform monitor circuit and high-speed digital control. We evaluated the proposed technique with the circuit simulation and the FPGA (field programmable gate array) and revealed the effectiveness to handle the packet data with quickly.

Academic Significance and Societal Importance of the Research Achievements |
光パケット伝送では、各ノードとの距離に応じて各パケット信号毎に信号振幅や波形劣化量の異なる信号を受信する必要がある。この課題を解決するために、複雑な制御が必要な高速波形整形をアナログ制御技術とディジタル制御技術を融合した新しい試みの検証に学術的な意義がある。本研究における高速波形整形技術により、例えば、光パケット伝送システムが使われている光加入者システムや、携帯電話の基地局システムの高速化・長距離化の可能性を示すことができた。
