Optical measurement and management system

This paper proposes an appreciate approach to alleviate the critical issues of using optical time domain reflectometer (OTDR) for monitoring and troubleshooting a conventional passive optical network (PON) equipped with passive branching device. In this enhancement, OTDR is located at central office (CO) and a tapper circuit is designed to allow the OTDR pulse bypassing the passive branching device in a conventional PON when emitted from CO towards customer sites in downstream direction. This provides a faster, simpler, and less complex way for surveillance applications. A simulation software named Smart Access Network _ Testing, Analyzing and Database (SANTAD) is developed for providing remote controlling, optical monitoring, fault detection, and centralized troubleshooting features to assist networks operators to manage PON more efficiency and deliver high quality of services (QoS) for end-users. SANTAD increases the workforce productivity and facilitates the network management of network through centralized monitoring and troubleshooting from CO.
