摘要
The present invention in a passive optical network failure detection method and a detection device , and with a detection device that the passive optical network is disclosed . ; in a passive optical network (PON) failure detection method according to the invention comprises: a) temporarily only when necessary while the PON is constantly in motion as may dongmang when supplied with power selectively configure the optical path of a remote node (RN); And b) is characterized in that incident to the monitor signal of the OTDR unit is located in a central office (CO) through the selectively configured optical path by a step of detecting a fault occurring on the selectively configured optical path .
