Detection Of Fiber Fault In FTTH Networking Using The Centralized Failure Detection System (CFDS)

Issues with fiber fault in fiber to the home (FTTH) customer access network often become a challenge to thenetwork service providers. The most important issues troubled the service providers and customer premisesare regarding the service reliability and safety. Conventionally, optical time domain reflectometer (OTDR) is used to detect the fiber fault and address the failure location in FTTH upwardly from customer sides towardcentral office (CO). However, OTDR can only display a measurement result of a testing line in a time and alsotime and cost misspend. By looking at the stated issues, a simple, attractive and user friendly graphical userinterface (GUI) is developed for Centralized Failure Detection System (CFDS) based on MATLAB programmingin this study. The developed program will be installed with optical line terminal (OLT) at the CO to centralizedmonitoring each optical fiber line’s status and identifying the failure location that occurs in the drop regionof FTTH downwardly from CO towards customer sides. CFDS is interfaced with OTDR to accumulate everynetwork testing result to be displayed on a single computer screen for further data analyzing. The analysisresults will be sent to field engineers or service providers for promptly actions.
