Abstract

In this paper, we discussed the mechanism of optical fiber break in time division multiplexing passive optical network (TDM-PON) and the upwardly or downwardly monitoring issues with conventional fiber fault localization technique by using optical time domain reflectometer (OTDR). We also studied the previous fault localization technology that had been recommended. Finally, we proposed a centralized inline monitoring and network testing system named as centralized failure detection system (CFDS). CFDS will be installed with optical line terminal (OLT) at the central office (CO) or network operation center to centrally monitoring each optical fiber line´s status and detecting the failure location that occurs in the multi-line drop region of fiber-to-the-home (FTTH) access network downwardly from CO towards the customer premises to improve the service reliability and reduce the restoration time and maintenance cost.
