Abstract—Resilience of a Passive Optical Network is the capacity to recover quickly from its failures and to resume back to its services soon after the failure condition. Resilience becomes a very important technique during the critical conditions of failure especially in the upcoming Next Generation-Optical Networks stage2 (ITU-T G. 989.2) when the network grows in high density, high speed and high data rate. Hence in this article, we have proposed a Fault Detection Module (FDM) and implemented in the NG-PON2 protection architecture for 2048 high-end subscribers using 2048 splitter for an extended reach of 100 Km Optical fiber distance. ITU-T G.984.1 outlines certain topologies for achieving redundancy.The proposed design is investigated and the simulation resultsshows that the protection architecture with proposed FDMexhibits low Total Round Trip Propagation Loss for ITU G.655.D corning LEAF fiber, low Network ConnectionAvailability of 0.9997 achieved for Type B protection which isexclusively required for business service providers whencompared with all other protection types without FDM.
