A METHOD FOR LOCATING FIBER EVENT POINT AND AN OPTICAL NETWORK AND NETWORK EQUIPMENT THEREOF

摘要

A method for locating fiber event point and an optical network and network equipment thereof are provided, the method comprises: determining the distance from the event point to the Optical Line Terminal (OLT); measuring the optical loss of the optical path from the OLT to the Optical Network Unit (ONU) or Optical Network Terminal (ONT) at the opposite terminal of the measured fiber link; determining whether the event point is on the measured fiber link based on the measured optical loss of the said optical path, if so, determining the event point's location on the measured optical link based on the distance from the event point to the OLT.
