H. Chan 他\u002708]により,波長群番号に依らず定義されるグルーミング率の制約を想定する時,小さなグルーミング率であっても効率の良い波長群パス収容が実現できることが示されている.そこで本稿では,波長群番号に依らず定義されるグルーミング率の制約を実現するコンパクトな階層型光クロスコネクトノード構成と,波長群番号への依存性を解決する新たな波長合分波器デバイスを提案する.従来型1階層光クロスコネクトノード構成及び階層型光クロスコネクトノード構成と,提案ノード構成のスイッチ規模比較により,その優位性を示す.本稿では同時に,提案ノード構成のプロトタイプシステムを構築し,伝送実験を行い,良好な伝送特性を確認する.

It was shown that node switch scale of the hierarchical optical path network node (Hierarchical Optical Cross-Connect: HOXC) can significantly be reduced when the grooming ratio, the ratio of number of groomed waveband paths to that of all incoming/outgoing waveband paths, is restricted [S. Kakehashi et al., 2008]. A recent work [L. H. Chau et al., 2008] elucidates that network with colorless grooming ratio restriction, which defmes grooming ratio regardless of the waveband index, can offer high efficiency of path utilization by utilizing a new effective design algorithm. In this paper, we develop a novel matrix-switch-based HOXC architecture and wavelength MTJX/DMUX that implement the colorless grooming ratio restriction. Numerical evaluations demonstrate that our proposed HOXC can significantly reduce node switch scale compared not only to the single-layer optical path network node (single-layer OXC) but also the conventional HOXC node that offers the same restriction. We also developed a prototype system of the proposed HOXC node and performed transmission experiments to verify its good transmission characteristics.", "subitem_description_language": "en",
