Abstract
A self-healing WDM-PON access ring architecture with high-reliable remote nodes is proposed and demonstrated in this paper. Four protecting modes are designed for protection of different fiber failures. The protecting fiber of the central ring can provide protection for working fiber. Optical line terminal and remote nodes can automatically switch to protecting fiber when working fiber fails. Network scale and system reliability are also analyzed at the end of this paper.
