ABSTRACT
Conventional optical code division multiple access (OCDMA) system for passive optical network (PON) has
limited applications in providing protection to network components. This increases the overall downtime of PON, and
reduce its feasibility for deployment at the access domain. Therefore, it is imperative to design an economical system
that should be able to provide fault detection and restoration at both feeder and the distribution level. This paper
focuses on design and analysis of a novel tree-based hybrid protection architecture for OCDMA system in order to
make it economical and reliable for deployment at the access domain. It is observed that the proposed protection
architecture provides desirable (5 nines) connection availability along with minimum cost as compared to existing
tree based protection architectures.
