Abstract :
The author studies reliability in the all-optical partitioned passive stars (POPS) topology. POPS is a physical architecture to scale the traditional optical passive star couplers and explore the advantages of high noise immunity and single-hop. The reliability and fault tolerance in POPS rely on its connectivity. The author analyzes the worst case for network partitions due to either node failures or link errors. For node connectivity, the author shows that the whole system remains connectivity no matter how many nodes don´t work. For link connectivity, the author analyzed some worst cases due to link errors and the lower bound for connectivity is demonstrated. Some sufficient approaches are proposed to detect and keep connectivity of the whole system
