Abstract: In this study, we propose and experimentally demonstrate a simple self-protection architecture for WDM passive optical network (PUN) by adding a novel 2x2 optical switch design in each optical networking unit (ONU). Two adjacent ONUs are interconnected into a group. By using the proposed protection architecture, the affected traffic can be restored immediately against fiber fault in the feeder and distributed fibers. Moreover, the performance of proposed self-protection WDM-PON is also discussed and analyzed. (C) 2011 Elsevier B.V. All rights reserved.
