摘要
A simply self-restored ring-based time-division-multiplexed passive optical network by a clockwise and counterclockwise circulating fiber against the fiber fault in an access system is proposed and experimentally investigated. The proposed optical line terminal and optical network unit modules can be used to prevent and protect the occurrence of fiber failure in the ring-based passive optical networks (PONs). Using the proposed self-healing access network, the ring-based PON can be revived promptly under fiber failure. The protection and restoration time of the access network is measured within 7 ms. In addition, the performance of data traffic in the access network is also discussed. (C) 2008 Optical Society of America.
