Executive Summary

This paper presents fiber fault monitoring approaches for Fiber-To-The Home (FTTH) with a Passive Optical Network (PON). Current fiber fault monitoring approaches are difficult to be implemented due to its complexity and high loss as the amount of branches increase. Approach: A fiber fault monitoring scheme is proposed whereas Fiber Bragg Grating (FBG) is placed on each branch of the Optical Network Unit (ONU). The advantages of the scheme are that it is simple, low cost and efficient in monitoring fiber fault in ONU. FTTH based network design is simulated using Opti-system 8.0 in order to investigate the feasibility of the proposed scheme.
