Abstract
A method for locating fiber events and an optical network and network device are provided. The method for locating fiber events includes: determining the distance between an event and an OLT, measuring the optical loss of the optical channel between the OLT and an ONU or ONT at the peer end of the measured fiber link, and, according to the measured optical loss of the optical channel, judging whether the event occurs on the measured fiber link, and if so, determining the location of the event on the measured fiber link according to the distance between the event and the OLT.
