次世代光ホームバックボーンネットワーク構成

Abstract

This paper first introduces the general physical network configurations with some features. It then evaluates the network feasibility of the double star (DS) configuration by the path loss evaluation method. The remaining path loss that is the permitted loss value for the given link is discussed by considering several actual device characteristics. It is clarified that the DS is feasible, however, the system with larger number of splitting port might also feasible when the splitter has lower excess loss or the network is relatively small. With some experimental results that were recently obtained by the authors and other, the network is feasible, however, requires further researches to advance device characteristics.
