Abstract

This study highlights Centralized Failure Detection System (CFDS) that specially developed for centralized monitoring and degradation/failure detection in passive optical network (PON)-based Intelligent Fiber-To-the-Home (i-FTTH) from Central Office (CO) in the downstream direction. This simple and cost-effective technique detects and localizes the fiber failures in point-to-multipoint (P2MP) networks by monitoring the loss of a reflective event that indicates presence of component at the same location. The failures in drop fibers as well as feeder fiber can be localized by accessing a commercially available Optical Time Domain Reflectometry (OTDR) for conducting live testing and service monitoring from CO through Smart Access NetworkTesting, Analyzing and Database (SANTAD). SANTAD is successfully detecting a fault occurred at distance 11.4152 km from CO in PON-based i-FTTH network testbed composed of 19.4 km with system loss 20.85 dB within 15 min by setting the acquisition parameters in OTDR with operating wavelength and pulse width equal to 1625 nm and 1 usec, respectively. This method provides a distance deviation up to 65 m from the exact failure location in real scenario.
