Method for pinpointing a faulty network terminal in a Passive Optical Network (PON)

摘要

This method is used for pinpointing (identifying, diagnosing) a faulty network terminal in a passive optical network (PON) comprising an optical line termination, a splitter upwardly connected the optical line termination through a single fibre and network terminals connected to the splitter.;This method comprises the following steps consisting of subsequently:sending from the optical line termination on a one probed terminal basis a request to one network terminal for transmitting a testing signal,attempting from the requested network terminal to transmit the testing signal,analysing the signal received at the optical line termination issued from the splitter in order to detect the testing signal and provide a detection result ,determining whether the probed network terminal is a faulty terminal on the basis of the detection result.
