This paper focuses on developing a simple, attracting and user-friendly graphical user interface (GUI) for centralized failure detection system (CFDS) by using MATLAB software. The developed program will be installed with optical line terminal (OLT) at central office (CO) to centrally monitoring each optical fiber line's status and detecting the failure location that occurs in the drop region of fiber to the home (FTTH) access network downwardly from CO towards customer premises. Conventionally, the faulty fiber and failure location can be detected by using optical time domain reflectometer (OTDR) upwardly from customer premises towards CO. However, OTDR can only display a single result of a line in a time and also time and cost misspend. CFDS is interfaced with the OTDR to accumulate every network testing result to be displayed on a single computer screen for further analysis. The program will identify and present the parameters of optical line such as the line's status either in working or nonworking condition, magnitude of decreasing, failure location and other details as shown in the OTDR's screen. The analysis result will be sent to field engineers or service providers for promptly action.
