Abstract :
Passive Optical Network (PON) is the promising technology in future broadband access networks. Protection is an important and imperative issue in PON system while protection of cascaded PON (with two-stage splitter or more) system has been ignored. This paper presents a comprehensive study on protection strategy for cascaded PON system. The reliability and protection issues of cascaded PON are studied using theoretical analysis and numerical simulations. A function called Reliability Cost Ratio (RCR) is presented to evaluate the performance of different protection strategies. Simulation shows the variation trend of RCR with different splitter schemes.
