Outline of Final Research Achievements

In high-speed optical communication systems, transmitting data management information such as transmission channel (number) information and signal monitoring information without modifying the data frame configuration, and performing high-speed routing and bandwidth control based on that information, will greatly contribute to "realizing a flexible and reliable high-speed communication system." In this study, with the aim of realizing a flexible and reliable communication system, we propose a PAM4 transmission method adopted as a bulk transmission method, and evaluate the relationship between the performance of the proposed method, which superimposes (adds on) and transmits data management information onto the data frame signal using frequency modulation technology, and the circuit configuration of the transmitting and receiving transceivers, with the aim of realizing a high-performance ultra-high-speed communication system.

Academic Significance and Societal Importance of the Research Achievements

本研究により，高速ネットワークのフレキシブル化・高信頼化に大きく寄与する．ここで，一括伝送しているチャネル信号の番号（組み合わせ）情報・信号監視情報等のデータ管理情報を，元のデータフレーム構成を改変することなく重畳（アドオン）して同時に伝送する技術が，プロセッサ不要で確立されれば，それら情報に基づくフレキシブルなルーティングと高信頼なネットワーク運用が低コストで実現可能となる．
