Abstract :
We present a method to monitor single- and cascaded-splitter TDM-PON systems based on combined techniques of Optical Time-Domain Reflectometry (OTDR) and Optical Transceiver Monitoring (OTM). The method is non-invasive to data traffic flow and requires no additional functionality (hardware or software) at the Optical Network Terminals (ONT). The description of the Fiber Plant Manager (FPM) overall architecture and components is followed by measurement results proving the concept on a 25-km 1:32 PON testbed.
