Title:
光アクセスシステム
Document Type and Number:
Japanese Patent JP5704694
Kind Code:
B2
Abstract:
An optical access system is provided that enables subscriber terminals or termination devices to be interconnected via dedicated lines as needed, with respect to subscriber terminals or termination devices participating in an optical network. The optical network is a network connecting a plurality of accommodating stations, and in this network, the accommodating stations have a plurality of optical line termination devices and optical path selection means, the subscriber side optical terminals or optical line termination devices are connected in single star optical paths, and the optical line termination devices in the accommodating stations are connected with the above mentioned optical terminals or optical line termination devices via the optical path selection means. In this optical network, in the case of a subscriber side optical terminal or optical line termination device (A) connecting to an optical line termination device (B) in an accommodating station (X), a dedicated optical line is established via the optical path selection means in the accommodating station, and in the case of a subscriber side optical terminal or optical line termination device (A) connecting to an optical line termination device (C) in another accommodating station (Y), a dedicated optical line is established via the optical path selection means in the accommodating station (X), the optical network, and the optical path selection means in the other accommodating station (Y).
