This paper highlights on online monitoring, protection switching and fast restoration approach for fiber to the home-passive optical network (FTTH-PON) using Access Control System (ACS). ACS is developed for downwardly monitoring and failure detection from central office (CO) towards customer premises. ACS also provides activation of switching in the restoration scheme at the drop region of FTTH-PON. Customer protection device (CPD) comprises of programmable optical switches will be employed at the customer premises which stationed just before the ONU to ensure high survivability. We proposed and experimentally demonstrated a new inline monitoring and testing system with the combination of passive in-line monitoring (PIM) device and Centralized Failure Detection System (CFDS) for transmission surveillance and failure detection without affecting the triple-play service delivery in fiber-to-the-home …
