Restoration scheme issues in fiber to the home Ethernet passive optical network (FTTH-EPON)

The smart and intelligent system of FTTH is expected to be a key element which provides centralized monitoring, survivability and instantly maintenance of FTTH customer access network. A challenging task for network planners is to reduce network protection costs while maintaining an acceptable level of survivability. In this paper, we implement a cost effective restoration scheme for a novel tree-based EPON architecture for Intermediate Split Structure (ISS) in the drop region section. The protection mechanism for tree based optical switch will have capability to divert the signal onto protection line according to the types of failure condition and location of failures in access network. This will ensure the data flow continuously due to breakdown occur in the network and instantly repair operation before it cause any major problem later. We employ the dedicated and shared protection in our design. Four faulty conditions are considered in this article and OptiSystem, Inc. software is used to prove the solution feasibility.
