This paper presented a MATLAB-based system named Smart Access Network Testing, Analyzing and Database (SANTAD), purposely for in-service transmission surveillance and self restoration against fiber fault in tree-based structured optical access network. The developed program will be installed with optical line terminal (OLT) at central office (CO) to monitor the status and detect any fiber fault that occurs in the optical access network downwardly from CO towards customer premises. SANTAD is interfaced with optical time domain reflectometer (OTDR) to accumulate every network testing result to be displayed on a single computer screen and then specify the failure location in the network system. This approach has a bright prospect to improve the survivability and reliability as well as increase the efficiency and monitoring capability in a tree-based structured optical access network.
